Is there a standard deadline to appeal a dental claim?

No. On the six routes verified here the published first-step window runs from Delta Dental's 90-day claim adjustment to Cigna's 365 days in California, and Guardian publishes no filing deadline at all on its provider surfaces. The deadline that binds you is the one in your participation contract; the published figure is the payer's public statement.

Can a reconsideration be filed through the payer's portal?

It depends on the payer, and it is not safe to assume. Aetna files appeals through Availity and waives the paper form for portal filings; Cigna takes coding-edit reconsiderations through CignaforHCP.com or Provider.Evernorth.com; Delta Dental runs adjustments and disputes through Provider Tools. Guardian's portal publishes no appeal-submission function, and Guardian's, MetLife's, and United Concordia's New Jersey routes are written submissions.

Does a standalone dental plan get an external review?

Not a federal one - limited-scope dental is an excepted benefit and sits outside the rules carrying federal external review. State routes differ sharply: Louisiana expressly reaches dental insurance plans for individual claims over $250, while Illinois excludes dental-only policies from its external-review Act and New Jersey's arbitration program excludes dental service corporations and dental plan organizations.

This office requests reconsideration of the dental claim identified above, which was denied or adjusted by notice dated [DATE OF DENIAL NOTICE]. This office submits this request as the treating practice, on its own behalf, under the payer's published provider dispute process. The determination states the service was not medically necessary or did not meet a clinical criterion.

Please treat this letter as a formal request for reconsideration of that determination and for reprocessing of the claim as submitted.

Please state the specific plan provision, processing policy, or clinical criterion applied to this claim, and provide a copy of it with the decision.

This determination turns on clinical judgment. Please have a licensed dentist review it and state the reviewer's credentials in the decision.

The supporting record is enclosed and listed below. Please confirm receipt of each item, and identify any additional document required before a decision, rather than closing the request for want of documentation.

Please reprocess the claim and issue payment, or state in writing the specific plan provision, processing policy, or clinical criterion the decision rests on and provide a copy of it. Please also confirm the date this request was received and the date a decision is due, and identify any further level of review available and the deadline for it.

Before sending: read this letter against the denial notice and the patient's plan documents, replace every bracketed placeholder, and confirm the filing deadline and address printed on the notice itself.

Not in this letter

Florida: the 60-day internal-review clock — applies only in Florida.
New York: the 45-day floor on the filing period — applies only in New York.
Louisiana: the dental external-review route — applies only in Louisiana.

A paragraph that does not apply is left out, never swapped for a weaker one.

A shared link carries the four selections only — never your words and never a patient detail. Every identifier stays a bracketed placeholder you fill inside your own practice-management system.

How this letter is assembled

Every paragraph is a fixed string in this repository, written against one cited provision and carrying that citation on the page. The generator chooses which paragraphs apply to your selections, orders them, and joins them — it writes nothing of its own, draws no conclusion about your claim, and never softens or substitutes a paragraph whose conditions are not met. Where a paragraph does not apply it is listed as withheld, with the reason.

Citations were verified 2026-08-31 against the regulation, statute, or payer document linked beside each element. Provider contracts and plan documents override published manuals, so confirm the deadline and address on the notice you actually received.

Nothing you type here leaves your browser — the results are computed locally on this page.

The letter generator runs entirely in your browser — enable JavaScript to use it. Every element it can carry, with its citation and its exact letter text, is listed below in plain HTML.

When to use this letter

A commercial dental payer denied or underpaid a claim and you are inside the payer's own published window.
You want the letter to name the payer's own route, form, and address rather than a generic one.
You need the specific plan provision or processing policy the payer applied, in writing.

When not to

The plan is a self-funded employer plan or a Medicaid managed-care plan - both have their own letters here, on different authority.
The dispute is about the interpretation of your participation agreement. Guardian, for one, sends those to binding arbitration rather than appeal.
The denial type is a member appeal, not a provider appeal. Read the notice first.

Every element this letter can carry, and the provision behind it

A paragraph with no citation is marked as a request rather than an entitlement, because that is what it is.

Element	What the rule gives	Authority and scope
What is disputed, and what is being asked forAlways included	The letter states the claim, the determination, and the outcome requested. A reconsideration that does not say what it wants gets read as correspondence.	No citation — a request, not an entitlementStructural, not an entitlement. Every payer route here reads a written dispute.
The plan provision or criterion applied	Ask the payer to state the specific plan provision, processing policy, or clinical criterion the decision rests on, and to send a copy.	No citation — a request, not an entitlementA request, not an entitlement, on a fully insured commercial claim. Under an ERISA group health plan the equivalent is a notice-content duty at 29 CFR 2560.503-1(g)(1)(v)(A).
Who reviewed it	Ask for the credentials of the reviewer on a clinical denial, and for a licensed dentist review where the determination turns on dental judgment.	No citation — a request, not an entitlementA request. Guardian, for example, publishes a re-review by a different dentist consultant and a Peer to Peer Request as courtesy routes rather than entitlements.

The contract overrides the manual, and every payer says so

Cigna: if there is conflict between its reference guide and your provider agreement or applicable law, the agreement or the law supersedes the guide, and processes may vary by state mandate or contract provision. Delta Dental points contracted dentists to the Dentist Handbook, which is behind the Provider Tools login - every Delta deadline published anywhere else is a restatement of a contract Dentovio cannot read. DentaQuest manuals open with a line telling providers to refer to the participation agreement for the plans they contract with. United Concordia routes benefit-access grievances to the appeal procedure in the member's certificate of insurance, and its per-plan provider deadlines live in state-specific Dental Reference Guides behind provider login. Aetna publishes exceptions to its own 180-day filing standard for members covered under fully insured plans. Treat every published window here as the payer's public statement, and the number in your participation contract as the one that controls.

Some denials are the member's appeal, not yours

Cigna routes precertification denials for services not yet rendered, benefit denials, and maximum-reimbursable-amount denials as customer appeals rather than provider appeals. United Concordia's New Jersey route publishes a list of determinations that cannot be appealed at all: utilization review determinations, member ineligibility, coordination of benefits, fraud investigations, the allowable-charge amount, and contract-year or orthodontic-lifetime maximum denials. Guardian treats a dispute over the interpretation of your dentist agreement as binding arbitration, not an appeal. Read the notice to see whose appeal it is before writing in the practice's name.

Where the Guardian Direct and DHMO addresses come from

Guardian's Direct/DTC, DHMO, and Lehigh Valley appeal addresses are published on its Change Healthcare cyber-incident business-continuity page, not on a standing appeals page - the mailing block is introduced as an alternative while electronic channels were down. Guardian's newer Dentist Manual, seven months later, routes group and PPO appeals to a different address entirely, the Grievance Department at P.O. Box 981573.

Delta Dental is 39 companies, and their deadlines conflict

Delta Dental publishes a roster of member companies with their own addresses, phone numbers, and payer IDs, footed by a line that those companies are financially responsible for their own products. Two enrollee grievance forms sitting on the same index page prove the divergence: California promises a written response within 30 days, Pennsylvania gives 180 days to appeal. Confirm which member company underwrites the plan before relying on any published deadline, and read the deadline printed on your own EOB.

Delta Dental, member companies contact information

The P.O. Box 14589 address is the Federal Dental Plan's

That address is verified from OPM's 2026 MetLife Federal Dental Plan brochure, which is the official statement of benefits for that plan. A MetLife commercial group certificate sends appeals to the address indicated on the claim form instead, allows two internal appeals, and requires the letter to state whether it is the first or second appeal. Do not use the federal box for a commercial group.

Name the United Concordia product or the deadline is wrong

The commercial business and the TRICARE Dental Program are different products with different ladders, and the TRICARE numbers are the ones most often published as if they were national. The commercial per-plan deadline lives in the state-specific Dental Reference Guide behind the Highmark provider login; the route published here is New Jersey's.

A standalone dental plan has no federal external review

Limited-scope dental benefits are excepted benefits: in the group market when they are provided under a separate policy or are otherwise not an integral part of the plan (45 CFR 146.145(b)(3)(i)), where limited scope means benefits substantially all of which are for treatment of the mouth (146.145(b)(3)(iii)(A)); in the individual market the test is separate-policy only and the wording differs (45 CFR 148.220(b)(1)). Excepted benefits sit outside the market reforms that carry the federal internal-claims-and-external-review rules at 45 CFR 147.136, so no letter should promise federal external review on a standalone dental denial. Dental embedded in an ACA-compliant, non-grandfathered plan is a different matter and keeps 147.136. A state external-review route may still exist - the federal exemption does not erase one.

Payer routes, as each payer publishes them

Every route names its product. A payer absent from this list was not verified this pass; that is a gap in our coverage, not a finding that the payer publishes nothing.

Cigna · Commercial dental, national route

Filing window:: 180 calendar days from the date of the initial payment or denial notice, or from the date of the last payment adjustment. California is longer: providers in California have 365 calendar days.
Decision clock:: Cigna's page states the review will be completed in 60 days, and separately states notification of the dispute resolution within 75 business days. Both figures are on the same page.
Form:: Request for Health Care Professional Payment Review (Cigna's page calls it the Provider version; the PDF's own title line says Professional, and the Related Resources rail calls it the Appeal Request and Billing Dispute Resolution Form)
Mail to: Cigna Healthcare Inc. National Appeals Unit (NAO) PO Box 188011 Chattanooga, TN 37422

If the ID card shows the GWH-Cigna or G indicator, the appeal goes to PO Box 188062, Chattanooga, TN 37422 instead.
Cigna reserves further rights conditionally: a denial letter will outline any additional appeal rights, if applicable. The words single-level process appear only on Cigna's California page, and only for Connecticut General Life Insurance Company and The Cigna Group Health and Life Insurance Company participants in California.
California providers get 365 calendar days from the initial payment or denial notice, not 180.
The linked form PDF has not been revised since 2015 and prints an older unit name and ZIP+4. Use the addresses on the live page.
Separate routes exist for EviCore (PO Box 5620, Hartford, CT 06102) and Express Scripts (PO Box 66588, St. Louis, MO 63166-6588).
Cigna's appeal-type taxonomy is not public - it sits in the National Reference Guide behind the CignaforHCP login.

Cigna, Appeals and Disputes Policy and Procedures Cigna, California provider dispute resolution

Aetna · Commercial dental, national route

Filing window:: Reconsideration: 180 calendar days from the initial claim decision. Appeal: 60 calendar days from the reconsideration decision, or 180 calendar days where the issue is medical need or experimental and investigational criteria.
Decision clock:: Reconsideration: an EOB or letter within 30 business days. Appeal: a decision by mail or fax within 60 business days. Post-service appeals are not eligible for expedited handling.
Form:: Practitioner and Provider Complaint and Appeal Request, form GR-69140 (3-17). The Medicare variant is GR-69608 (6-21) and mails to PO Box 14835.
Mail to: Aetna Provider Resolution Team PO Box 14020 Lexington, KY 40512

Reconsideration mail is state-routed, not one national address: PO Box 14079, Lexington, KY 40512-4079 for AL, AK, AR, AZ, CA, FL, GA, HI, ID, LA, MS, NC, NM, NV, OR, SC, UT, TN and WA, and PO Box 981106, El Paso, TX 79998-1106 for the remaining listed states and DC.
Aetna publishes exceptions to its own 180-day filing standard for members covered under fully insured plans, so the number needs a state-law and contract check.
Misrouting is self-correcting: Aetna states that a reconsideration that should have been an appeal gets routed to the right place.
Fax for commercial appeals: 1-859-455-8650.

Delta Dental · Provider claim adjustment and dispute, as published by Delta Dental

Filing window:: Claim adjustment: claims submitted within the past 90 days. Provider dispute: only after a claim-adjustment denial, and not for issues older than 365 days from Delta Dental's last action or inaction.
Decision clock:: An answer on an adjustment request within 30 days; a written response to a provider dispute within 45 working days. Receipt is acknowledged within 2 working days through the provider portal, or 15 working days by mail.
Form:: Provider Inquiry Form for escalation. The separate Provider Dispute Form is program-scoped - its mail block routes to the Washington DC HSCSN Medicaid Program. There is no Delta Dental form 1A.
Mail to: Delta Dental - resubmissions and provider disputes P.O. Box 997330 Sacramento, CA 95899-7330

Delta Dental is a federation of 39 member companies that are financially responsible for their own products, and the deadlines genuinely conflict between them: two enrollee grievance forms published on the same index page give California a 30-day written response and Pennsylvania 180 days to appeal.
The binding instrument is the Dentist Handbook, which sits behind the Provider Tools login. Every deadline here is a marketing-collateral restatement of a contract Dentovio cannot read.
The Provider Tools escalation guide carrying the 90-day figure is dated 12/22 - re-check it against the current guide before relying on it.
The claim-adjustment step is a prerequisite: disputes are processed only where the provider first attempted to resubmit the claim for adjustment.

MetLife (Federal Dental Plan) · MetLife Federal Dental Plan (FEDVIP), brochure 02AP-11, 2026

Filing window:: 180 days from the date of receipt of the decision. The commercial group certificate uses the same 180 days from receiving MetLife's decision.
Decision clock:: A written or electronic explanation of the benefit determination within 30 days of receipt of the request. Under the commercial certificate, MetLife notifies in writing within 30 days after receipt, with up to an additional 30 days in special circumstances.
Form:: None. The disputed-claims process names no form; a written request is what it asks for.
Mail to: MetLife Dental Claims Appeals P.O. Box 14589 Lexington, KY 40512

The P.O. Box 14589 address is verified for the Federal Dental Plan only. A MetLife commercial group certificate (GCERT2000) routes appeals to the address indicated on the claim form - a per-plan variable, not a fixed box.
The commercial certificate allows two appeals and requires the letter to state whether it is the first or the second appeal, along with the employee name, the plan name, a reference to the initial decision, and an explanation of why the determination is being appealed.
The claims address is not the appeals address: FEDVIP claims go to MetLife Dental Claims, P.O. Box 981282, El Paso, TX 79998-1282, with a 13-month claim filing deadline.
Arizona members are governed by MetLife's Arizona appeals packet, which allows two years from an adverse determination to begin the appeal process and states members are not required to use the state forms.

United Concordia (New Jersey commercial) · Commercial dental in New Jersey

Filing window:: 180 calendar days to file the appeal.
Decision clock:: Internal review decision within 30 calendar days.
Form:: Health Care Provider Application to Appeal a Claims Determination
Mail to: United Concordia Attn: Appeals Department PO Box 69420 Harrisburg, PA 17106-9420

New Jersey publishes a hard non-appealable list: utilization review determinations, member ineligibility, coordination of benefits, fraud investigations, the allowable-charge amount, and contract-year or orthodontic-lifetime maximum denials.
This is the New Jersey commercial route. United Concordia's per-plan commercial deadlines live in state-specific Dental Reference Guides behind the Highmark provider login; there is no single national United Concordia appeal deadline to publish.
The TRICARE Dental Program is a different product on a different ladder: reconsideration to United Concordia within 90 calendar days of the DEOB issue date at PO Box 69450, Harrisburg, PA 17106; then a Defense Health Agency formal review within 60 days where $50 or more remains in dispute; then a DHA hearing within 60 days where $300 or more remains in dispute, at 16401 E. Centretech Parkway, Aurora, CO 80011-9066.
The provider surface is called Provider Online Services, with tiles for My Patients' Benefits and Payments & EOBs. My Account is a member-side label on the TRICARE site, and the only "Provider Portal" on either domain belongs to a third-party remittance vendor.
New Jersey's PICPA arbitration does not hear claims against dental service corporations or dental plan organizations - see the state routes below.

Guardian · DentalGuard group and PPO, plus the Guardian Direct and DHMO routes

Filing window:: Guardian publishes no filing deadline on the surfaces read for this pass; the response time is what it commits to. Check the plan documents and the participation agreement for the filing window.
Decision clock:: A decision within 60 days after receipt of the request, 45 days for disability appeals, or less where the state requires a shorter response time.

State escalation routes, and whether they reach standalone dental

Two of these five do not reach a dental-only plan at all. Saying so is the point of the table.

Florida · Conditional

Statutory internal-appeal clock and prompt-pay duties

Yes for a policy the statute reaches. Section 627.6131 applies to a major medical expense health insurance policy and, expressly, to a group or individual insurance contract that only provides direct payments to dentists for enumerated dental services - cite subsection (15) whenever asserting the statute reaches a standalone dental policy.

Window: A health insurer's internal dispute resolution process on a denied claim not under active review by a mediator, arbitrator, or third-party dispute entity must be finalized within 60 days after receipt of the provider's request for review or appeal. Filed with: The insurer or HMO, under its own dispute-resolution process.

The statute may not be waived, voided, or nullified by contract - section 627.6131(10) and section 641.3155(9).
Payment clocks run alongside: pay or contest within 20 days of an electronic claim and 40 days of a paper claim; a claim must be paid or denied within 90 days, and failure to pay or deny within 120 days creates an uncontestable obligation to pay (120/140 days for paper).
A provider has 35 days to supply requested additional information, and the insurer's contest notice must be accompanied by an itemized list of what it needs and may not request duplicate documents.
12% simple interest accrues on late payment from the date the claim should have been paid, denied, or contested, and is payable with the claim.
One missed deadline is not automatically fineable: the statute establishes a permissible error ratio of 5 percent for claims payment violations.
Dentists are reached through the catch-all for any other noninstitutional provider, not by enumeration - chapter 466 is not named in either statute's claim definition.

Section 627.6131, Florida Statutes (2026)Section 641.3155, Florida Statutes (2026)

Illinois · Does not reach standalone dental

Health Carrier External Review Act, 215 ILCS 180

No. The Act expressly does not apply to a policy or certificate that provides coverage only for dental, among other limited benefits, and the Department of Insurance repeats the exclusion. Self-funded employer, union, church, and non-federal governmental plans are out as well.

Window: Four months from receipt of the notice of adverse determination or final adverse determination, for the policies the Act does reach. Filed with: The Director of the Illinois Department of Insurance, who randomly assigns an independent review organization from the approved list.

Internal appeal must be exhausted first, deemed exhausted at 30 days for concurrent or prospective review, 60 days for retrospective review, or 48 hours on an expedited internal review.
The external review decision is binding on the health carrier; it binds the covered person only to the extent no other remedy is available under federal or state law.
There is no cost to the consumer; the carrier is solely responsible for the cost.
One bite only - no second external review of the same determination.

Louisiana · Reaches standalone dental

Internal Claims and Appeals Process and External Review Act, R.S. 22:2391 et seq.

Yes, and Louisiana is unusual in this. Act 89 of 2021 added a notwithstanding override at R.S. 22:2392(26): notwithstanding excepted benefits as defined in R.S. 22:1061, a health benefit plan subject to Part III of the Chapter includes dental insurance plans. Dental remains an excepted benefit in Louisiana generally - the override is scoped to the external-review Part only.

Window: Four months after receipt of the notice of adverse determination or final adverse determination. Filed with: The health insurance issuer, not the Department of Insurance. The issuer then requests assignment of an independent review organization through the Department's website, and the commissioner randomly assigns one.

Dollar floor: for claims related to a dental insurance policy the Chapter applies only to individual claims in excess of $250 - strictly more than, so a claim of exactly $250.00 does not qualify.
Denial type: Part III reaches only medical necessity, appropriateness, health care setting, level of care, effectiveness, experimental or investigational treatment, or a rescission. A plain benefit-limit, frequency-limit, missing-tooth-clause, or not-a-covered-service denial is not externally reviewable.
The internal claims and appeals process must be exhausted under R.S. 22:2401 unless the covered person is excused from exhausting.
The Chapter binds health insurance issuers, so a self-funded employer dental plan is outside it.
On a favorable external review the issuer must immediately approve the coverage or payment at issue.

La. R.S. 22:2392 (Louisiana Legislature)La. R.S. 22:2393 (Louisiana Legislature)La. R.S. 22:2436 (Louisiana Legislature)Act No. 89 (2021 Regular Session), SB 82 enrolled

Utilization review appeals and the Department of Financial Services external appeal

Only through a DFS-regulated insurer or HMO, and only for the right denial type. The DFS external appeal covers medical necessity, experimental or investigational, and out-of-network denials; it is not a route for self-funded plans, Medicare, or Medicaid fee-for-service.

Window: A utilization review agent must allow no less than 45 days to file the internal appeal from a utilization review adverse determination. For the DFS external appeal: four months for the insured, 60 days for a provider filing on its own behalf. Filed with: The plan for the internal utilization review appeal; the Department of Financial Services for the external appeal.

A provider's own-behalf external appeal exists only in connection with concurrent and retrospective adverse determinations; the Department of Health describes the provider route as retrospective only.
Provider standing on a utilization review appeal likewise attaches in connection with retrospective adverse determinations.
Do not cite health.ny.gov's External Appeals page for the deadline - it still prints a superseded 45-day figure. The statute and DFS both say four months.

Program for Independent Claims Payment Arbitration (PICPA), administered by MAXIMUS for DOBI under HCAPPA

Not against a dental carrier. DOBI states that claim disputes submitted to a self-funded entity, the State Health Benefits Program, a dental service corporation, or a dental plan organization are not eligible for resolution through PICPA. A dental practice reaches PICPA only on a medical plan issued by an eligible carrier.

Window: 90 calendar days after receiving the carrier's determination on the provider's internal claims-payment appeal. Filed with: MAXIMUS, through DOBI's arbitration program, after the carrier's internal claims-payment appeal.

The threshold is $1,000 or more, not more than $1,000 - a dispute of exactly $1,000 qualifies. Claims may be aggregated by carrier and covered person, or by carrier and CPT code, to reach it.
The internal appeal must have been filed on DOBI's Health Care Provider Application to Appeal a Claims Determination form; a determination on an appeal filed any other way is not eligible for arbitration at all.
Where the carrier never responds, the 90 days runs from the date the determination was due, and the provider may proceed without waiting.
Services must have been rendered on or after July 11, 2006. Out-of-state-issued policies, Medicaid fee-for-service, PIP and bodily-injury, and workers' compensation are also excluded.

Common questions

Is there a standard deadline to appeal a dental claim?: No. On the six routes verified here the published first-step window runs from Delta Dental's 90-day claim adjustment to Cigna's 365 days in California, and Guardian publishes no filing deadline at all on its provider surfaces. The deadline that binds you is the one in your participation contract; the published figure is the payer's public statement.
Can a reconsideration be filed through the payer's portal?: It depends on the payer, and it is not safe to assume. Aetna files appeals through Availity and waives the paper form for portal filings; Cigna takes coding-edit reconsiderations through CignaforHCP.com or Provider.Evernorth.com; Delta Dental runs adjustments and disputes through Provider Tools. Guardian's portal publishes no appeal-submission function, and Guardian's, MetLife's, and United Concordia's New Jersey routes are written submissions.
Does a standalone dental plan get an external review?: Not a federal one - limited-scope dental is an excepted benefit and sits outside the rules carrying federal external review. State routes differ sharply: Louisiana expressly reaches dental insurance plans for individual claims over $250, while Illinois excludes dental-only policies from its external-review Act and New Jersey's arbitration program excludes dental service corporations and dental plan organizations.

What these generators will not do - on purpose

They do not give legal advice. These are document-assembly tools: they place text you select into a letter you review, sign, and send. They do not apply legal judgment to your situation, and nothing here is a legal opinion about your claim, your contract, or your rights.
They make no claim about whether an appeal will succeed. There is no success rate on this page, no estimate of recovery, and no promise that a letter changes an outcome. Anyone quoting one to you should be asked for the evidence behind it.
They never ask for patient information. Names, birth dates, member IDs, claim numbers, and dates render as bracketed placeholders you fill in inside your own practice-management system. Nothing you type here leaves your browser.
They will not promise a route that does not exist. Federal external review does not attach to a standalone dental plan; Illinois excludes dental-only policies from its external-review Act; New Jersey's arbitration program excludes dental service corporations and dental plan organizations. Where a route is closed, the page says so instead of filling the gap.
They will not tell you your contract loses to a manual. Every payer here says the opposite: the provider agreement or applicable law supersedes the published guide. Published windows are the payer's public statement; the number in your contract controls.
The boundary of legal practice is a state question. The ABA recommended in August 2003 that every state adopt its own definition of the practice of law, on the basic premise that practising law is the application of legal principles and judgment to the circumstances or objectives of another person or entity, and left to each state who may provide those services. Its report also notes that drafting and selecting legal documents inherently involves legal advice. That is why these tools assemble and cite rather than advise - and why a state-specific question belongs with a licensed attorney in that state.

This office requests reconsideration of the dental claim identified above, which was denied or adjusted by notice dated [DATE OF DENIAL NOTICE]. This office submits this request as the treating practice, on its own behalf, under the payer's published provider dispute process. The determination states the service was not medically necessary or did not meet a clinical criterion.

Please treat this letter as a formal request for reconsideration of that determination and for reprocessing of the claim as submitted.

Please state the specific plan provision, processing policy, or clinical criterion applied to this claim, and provide a copy of it with the decision.

This determination turns on clinical judgment. Please have a licensed dentist review it and state the reviewer's credentials in the decision.

The supporting record is enclosed and listed below. Please confirm receipt of each item, and identify any additional document required before a decision, rather than closing the request for want of documentation.

Please reprocess the claim and issue payment, or state in writing the specific plan provision, processing policy, or clinical criterion the decision rests on and provide a copy of it. Please also confirm the date this request was received and the date a decision is due, and identify any further level of review available and the deadline for it.

Enclosures:
- Copy of the denial notice or remittance dated [DATE OF DENIAL NOTICE]
- Copy of the claim as submitted, with attachments

How this letter is assembled

Nothing you type here leaves your browser — the results are computed locally on this page.

The letter generator runs entirely in your browser — enable JavaScript to use it. Every element it can carry, with its citation and its exact letter text, is listed below in plain HTML.

When to use this letter

A commercial dental payer denied or underpaid a claim and you are inside the payer's own published window.
You want the letter to name the payer's own route, form, and address rather than a generic one.
You need the specific plan provision or processing policy the payer applied, in writing.

When not to

The plan is a self-funded employer plan or a Medicaid managed-care plan - both have their own letters here, on different authority.
The dispute is about the interpretation of your participation agreement. Guardian, for one, sends those to binding arbitration rather than appeal.
The denial type is a member appeal, not a provider appeal. Read the notice first.

Every element this letter can carry, and the provision behind it

A paragraph with no citation is marked as a request rather than an entitlement, because that is what it is.

Element	What the rule gives	Authority and scope
What is disputed, and what is being asked forAlways included	The letter states the claim, the determination, and the outcome requested. A reconsideration that does not say what it wants gets read as correspondence.	No citation — a request, not an entitlementStructural, not an entitlement. Every payer route here reads a written dispute.
The plan provision or criterion applied	Ask the payer to state the specific plan provision, processing policy, or clinical criterion the decision rests on, and to send a copy.	No citation — a request, not an entitlementA request, not an entitlement, on a fully insured commercial claim. Under an ERISA group health plan the equivalent is a notice-content duty at 29 CFR 2560.503-1(g)(1)(v)(A).
Who reviewed it	Ask for the credentials of the reviewer on a clinical denial, and for a licensed dentist review where the determination turns on dental judgment.	No citation — a request, not an entitlementA request. Guardian, for example, publishes a re-review by a different dentist consultant and a Peer to Peer Request as courtesy routes rather than entitlements.
The record is enclosed	Name what is enclosed so the payer cannot close the dispute for want of documentation it already has.	No citation — a request, not an entitlementStructural.
Florida: the 60-day internal-review clock	Florida requires an insurer's or HMO's internal dispute resolution process on a denied claim to be finalized within 60 days after receipt of the provider's request for review or appeal, and the section may not be waived by contract.	s. 627.6131(8) and (10), Fla. Stat.; s. 641.3155(7) and (9)627.6131(8) and (10); 641.3155(7) and (9)Reaches a standalone dental contract through s. 627.6131(15), which names a contract that only provides direct payments to dentists for enumerated dental services.
New York: the 45-day floor on the filing period	A New York utilization review agent must establish a period of no less than forty-five days in which to file an appeal from a utilization review adverse determination.	N.Y. Public Health Law section 4904(3)section 4904(3); provider standing at 4904(1)Utilization review adverse determinations. A provider's own standing attaches in connection with retrospective adverse determinations.
Louisiana: the dental external-review route	Louisiana pulls dental insurance plans into the external-review Part of R.S. 22:2391 et seq. for individual claims in excess of $250, on a medical-necessity-type denial, after the internal process is exhausted, filed with the issuer within four months.

Payer routes, as each payer publishes them

Every route names its product. A payer absent from this list was not verified this pass; that is a gap in our coverage, not a finding that the payer publishes nothing.

Cigna · Commercial dental, national route

Filing window:: 180 calendar days from the date of the initial payment or denial notice, or from the date of the last payment adjustment. California is longer: providers in California have 365 calendar days.
Decision clock:: Cigna's page states the review will be completed in 60 days, and separately states notification of the dispute resolution within 75 business days. Both figures are on the same page.
Form:: Request for Health Care Professional Payment Review (Cigna's page calls it the Provider version; the PDF's own title line says Professional, and the Related Resources rail calls it the Appeal Request and Billing Dispute Resolution Form)
Mail to: Cigna Healthcare Inc. National Appeals Unit (NAO) PO Box 188011 Chattanooga, TN 37422

If the ID card shows the GWH-Cigna or G indicator, the appeal goes to PO Box 188062, Chattanooga, TN 37422 instead.
Cigna reserves further rights conditionally: a denial letter will outline any additional appeal rights, if applicable. The words single-level process appear only on Cigna's California page, and only for Connecticut General Life Insurance Company and The Cigna Group Health and Life Insurance Company participants in California.
California providers get 365 calendar days from the initial payment or denial notice, not 180.
The linked form PDF has not been revised since 2015 and prints an older unit name and ZIP+4. Use the addresses on the live page.
Separate routes exist for EviCore (PO Box 5620, Hartford, CT 06102) and Express Scripts (PO Box 66588, St. Louis, MO 63166-6588).
Cigna's appeal-type taxonomy is not public - it sits in the National Reference Guide behind the CignaforHCP login.

Cigna, Appeals and Disputes Policy and Procedures Cigna, California provider dispute resolution

Aetna · Commercial dental, national route

Filing window:: Reconsideration: 180 calendar days from the initial claim decision. Appeal: 60 calendar days from the reconsideration decision, or 180 calendar days where the issue is medical need or experimental and investigational criteria.
Decision clock:: Reconsideration: an EOB or letter within 30 business days. Appeal: a decision by mail or fax within 60 business days. Post-service appeals are not eligible for expedited handling.
Form:: Practitioner and Provider Complaint and Appeal Request, form GR-69140 (3-17). The Medicare variant is GR-69608 (6-21) and mails to PO Box 14835.
Mail to: Aetna Provider Resolution Team PO Box 14020 Lexington, KY 40512

Reconsideration mail is state-routed, not one national address: PO Box 14079, Lexington, KY 40512-4079 for AL, AK, AR, AZ, CA, FL, GA, HI, ID, LA, MS, NC, NM, NV, OR, SC, UT, TN and WA, and PO Box 981106, El Paso, TX 79998-1106 for the remaining listed states and DC.
Aetna publishes exceptions to its own 180-day filing standard for members covered under fully insured plans, so the number needs a state-law and contract check.
Misrouting is self-correcting: Aetna states that a reconsideration that should have been an appeal gets routed to the right place.
Fax for commercial appeals: 1-859-455-8650.

Aetna, Disputes and Appeals Overview Aetna, Practitioner and Provider Complaint and Appeal Request (GR-69140)

Delta Dental · Provider claim adjustment and dispute, as published by Delta Dental

Filing window:: Claim adjustment: claims submitted within the past 90 days. Provider dispute: only after a claim-adjustment denial, and not for issues older than 365 days from Delta Dental's last action or inaction.
Decision clock:: An answer on an adjustment request within 30 days; a written response to a provider dispute within 45 working days. Receipt is acknowledged within 2 working days through the provider portal, or 15 working days by mail.
Form:: Provider Inquiry Form for escalation. The separate Provider Dispute Form is program-scoped - its mail block routes to the Washington DC HSCSN Medicaid Program. There is no Delta Dental form 1A.
Mail to: Delta Dental - resubmissions and provider disputes P.O. Box 997330 Sacramento, CA 95899-7330

Delta Dental is a federation of 39 member companies that are financially responsible for their own products, and the deadlines genuinely conflict between them: two enrollee grievance forms published on the same index page give California a 30-day written response and Pennsylvania 180 days to appeal.
The binding instrument is the Dentist Handbook, which sits behind the Provider Tools login. Every deadline here is a marketing-collateral restatement of a contract Dentovio cannot read.
The Provider Tools escalation guide carrying the 90-day figure is dated 12/22 - re-check it against the current guide before relying on it.
The claim-adjustment step is a prerequisite: disputes are processed only where the provider first attempted to resubmit the claim for adjustment.

MetLife (Federal Dental Plan) · MetLife Federal Dental Plan (FEDVIP), brochure 02AP-11, 2026

Filing window:: 180 days from the date of receipt of the decision. The commercial group certificate uses the same 180 days from receiving MetLife's decision.
Decision clock:: A written or electronic explanation of the benefit determination within 30 days of receipt of the request. Under the commercial certificate, MetLife notifies in writing within 30 days after receipt, with up to an additional 30 days in special circumstances.
Form:: None. The disputed-claims process names no form; a written request is what it asks for.
Mail to: MetLife Dental Claims Appeals P.O. Box 14589 Lexington, KY 40512

The P.O. Box 14589 address is verified for the Federal Dental Plan only. A MetLife commercial group certificate (GCERT2000) routes appeals to the address indicated on the claim form - a per-plan variable, not a fixed box.
The commercial certificate allows two appeals and requires the letter to state whether it is the first or the second appeal, along with the employee name, the plan name, a reference to the initial decision, and an explanation of why the determination is being appealed.
The claims address is not the appeals address: FEDVIP claims go to MetLife Dental Claims, P.O. Box 981282, El Paso, TX 79998-1282, with a 13-month claim filing deadline.
Arizona members are governed by MetLife's Arizona appeals packet, which allows two years from an adverse determination to begin the appeal process and states members are not required to use the state forms.

United Concordia (New Jersey commercial) · Commercial dental in New Jersey

Filing window:: 180 calendar days to file the appeal.
Decision clock:: Internal review decision within 30 calendar days.
Form:: Health Care Provider Application to Appeal a Claims Determination
Mail to: United Concordia Attn: Appeals Department PO Box 69420 Harrisburg, PA 17106-9420

New Jersey publishes a hard non-appealable list: utilization review determinations, member ineligibility, coordination of benefits, fraud investigations, the allowable-charge amount, and contract-year or orthodontic-lifetime maximum denials.
This is the New Jersey commercial route. United Concordia's per-plan commercial deadlines live in state-specific Dental Reference Guides behind the Highmark provider login; there is no single national United Concordia appeal deadline to publish.
The TRICARE Dental Program is a different product on a different ladder: reconsideration to United Concordia within 90 calendar days of the DEOB issue date at PO Box 69450, Harrisburg, PA 17106; then a Defense Health Agency formal review within 60 days where $50 or more remains in dispute; then a DHA hearing within 60 days where $300 or more remains in dispute, at 16401 E. Centretech Parkway, Aurora, CO 80011-9066.
The provider surface is called Provider Online Services, with tiles for My Patients' Benefits and Payments & EOBs. My Account is a member-side label on the TRICARE site, and the only "Provider Portal" on either domain belongs to a third-party remittance vendor.
New Jersey's PICPA arbitration does not hear claims against dental service corporations or dental plan organizations - see the state routes below.

Guardian · DentalGuard group and PPO, plus the Guardian Direct and DHMO routes

Filing window:: Guardian publishes no filing deadline on the surfaces read for this pass; the response time is what it commits to. Check the plan documents and the participation agreement for the filing window.
Decision clock:: A decision within 60 days after receipt of the request, 45 days for disability appeals, or less where the state requires a shorter response time.
Form:: None. Guardian's published route is a written letter of appeal.
Mail to: Guardian Grievance Department P.O. Box 981573 El Paso, TX 79998-1573 Fax: 1-509-468-6399

The address above is the group and PPO route from Guardian's own Dentist Manual (footer 08.25.2025). The Guardian Direct and DHMO addresses come from a different kind of page - see the caveats below.
Guardian Direct / DTC appeals: PO Box 981587, El Paso, TX 79998, and the Attn: DTC Appeals line is essential - 981587 is otherwise Guardian's dental claims box. DHMO and Managed Dental Care: PO Box 981571, El Paso, TX 79998-1571. A Lehigh Valley box, P.O. Box 25256, Lehigh Valley, PA 18002-5256, is labelled DHMO Appeals on guardianlife.com and the grievance address on the Guardian Dental Exchange site.
Those three addresses are published on Guardian's Change Healthcare cyber-incident business-continuity page, not on a standing appeals page. Treat them as continuity routing and confirm before sending.
Guardian publishes no Level 1 / Level 2 appeal ladder and no appeal form; a search of its 267-form public library returns nothing for appeal, dispute, or grievance.

State escalation routes, and whether they reach standalone dental

Two of these five do not reach a dental-only plan at all. Saying so is the point of the table.

Florida · Conditional

Statutory internal-appeal clock and prompt-pay duties

The statute may not be waived, voided, or nullified by contract - section 627.6131(10) and section 641.3155(9).
Payment clocks run alongside: pay or contest within 20 days of an electronic claim and 40 days of a paper claim; a claim must be paid or denied within 90 days, and failure to pay or deny within 120 days creates an uncontestable obligation to pay (120/140 days for paper).
A provider has 35 days to supply requested additional information, and the insurer's contest notice must be accompanied by an itemized list of what it needs and may not request duplicate documents.
12% simple interest accrues on late payment from the date the claim should have been paid, denied, or contested, and is payable with the claim.
One missed deadline is not automatically fineable: the statute establishes a permissible error ratio of 5 percent for claims payment violations.
Dentists are reached through the catch-all for any other noninstitutional provider, not by enumeration - chapter 466 is not named in either statute's claim definition.

Section 627.6131, Florida Statutes (2026)Section 641.3155, Florida Statutes (2026)

Health Carrier External Review Act, 215 ILCS 180

Internal appeal must be exhausted first, deemed exhausted at 30 days for concurrent or prospective review, 60 days for retrospective review, or 48 hours on an expedited internal review.
The external review decision is binding on the health carrier; it binds the covered person only to the extent no other remedy is available under federal or state law.
There is no cost to the consumer; the carrier is solely responsible for the cost.
One bite only - no second external review of the same determination.

Louisiana · Reaches standalone dental

Internal Claims and Appeals Process and External Review Act, R.S. 22:2391 et seq.

Dollar floor: for claims related to a dental insurance policy the Chapter applies only to individual claims in excess of $250 - strictly more than, so a claim of exactly $250.00 does not qualify.
Denial type: Part III reaches only medical necessity, appropriateness, health care setting, level of care, effectiveness, experimental or investigational treatment, or a rescission. A plain benefit-limit, frequency-limit, missing-tooth-clause, or not-a-covered-service denial is not externally reviewable.
The internal claims and appeals process must be exhausted under R.S. 22:2401 unless the covered person is excused from exhausting.
The Chapter binds health insurance issuers, so a self-funded employer dental plan is outside it.
On a favorable external review the issuer must immediately approve the coverage or payment at issue.

Utilization review appeals and the Department of Financial Services external appeal

A provider's own-behalf external appeal exists only in connection with concurrent and retrospective adverse determinations; the Department of Health describes the provider route as retrospective only.
Provider standing on a utilization review appeal likewise attaches in connection with retrospective adverse determinations.
Do not cite health.ny.gov's External Appeals page for the deadline - it still prints a superseded 45-day figure. The statute and DFS both say four months.

New Jersey · Does not reach standalone dental

Program for Independent Claims Payment Arbitration (PICPA), administered by MAXIMUS for DOBI under HCAPPA

The threshold is $1,000 or more, not more than $1,000 - a dispute of exactly $1,000 qualifies. Claims may be aggregated by carrier and covered person, or by carrier and CPT code, to reach it.
The internal appeal must have been filed on DOBI's Health Care Provider Application to Appeal a Claims Determination form; a determination on an appeal filed any other way is not eligible for arbitration at all.
Where the carrier never responds, the 90 days runs from the date the determination was due, and the provider may proceed without waiting.
Services must have been rendered on or after July 11, 2006. Out-of-state-issued policies, Medicaid fee-for-service, PIP and bodily-injury, and workers' compensation are also excluded.

Common questions

Is there a standard deadline to appeal a dental claim?: No. On the six routes verified here the published first-step window runs from Delta Dental's 90-day claim adjustment to Cigna's 365 days in California, and Guardian publishes no filing deadline at all on its provider surfaces. The deadline that binds you is the one in your participation contract; the published figure is the payer's public statement.
Can a reconsideration be filed through the payer's portal?: It depends on the payer, and it is not safe to assume. Aetna files appeals through Availity and waives the paper form for portal filings; Cigna takes coding-edit reconsiderations through CignaforHCP.com or Provider.Evernorth.com; Delta Dental runs adjustments and disputes through Provider Tools. Guardian's portal publishes no appeal-submission function, and Guardian's, MetLife's, and United Concordia's New Jersey routes are written submissions.
Does a standalone dental plan get an external review?: Not a federal one - limited-scope dental is an excepted benefit and sits outside the rules carrying federal external review. State routes differ sharply: Louisiana expressly reaches dental insurance plans for individual claims over $250, while Illinois excludes dental-only policies from its external-review Act and New Jersey's arbitration program excludes dental service corporations and dental plan organizations.

What these generators will not do - on purpose

They do not give legal advice. These are document-assembly tools: they place text you select into a letter you review, sign, and send. They do not apply legal judgment to your situation, and nothing here is a legal opinion about your claim, your contract, or your rights.
They make no claim about whether an appeal will succeed. There is no success rate on this page, no estimate of recovery, and no promise that a letter changes an outcome. Anyone quoting one to you should be asked for the evidence behind it.
They never ask for patient information. Names, birth dates, member IDs, claim numbers, and dates render as bracketed placeholders you fill in inside your own practice-management system. Nothing you type here leaves your browser.
They will not promise a route that does not exist. Federal external review does not attach to a standalone dental plan; Illinois excludes dental-only policies from its external-review Act; New Jersey's arbitration program excludes dental service corporations and dental plan organizations. Where a route is closed, the page says so instead of filling the gap.
They will not tell you your contract loses to a manual. Every payer here says the opposite: the provider agreement or applicable law supersedes the published guide. Published windows are the payer's public statement; the number in your contract controls.
The boundary of legal practice is a state question. The ABA recommended in August 2003 that every state adopt its own definition of the practice of law, on the basic premise that practising law is the application of legal principles and judgment to the circumstances or objectives of another person or entity, and left to each state who may provide those services. Its report also notes that drafting and selecting legal documents inherently involves legal advice. That is why these tools assemble and cite rather than advise - and why a state-specific question belongs with a licensed attorney in that state.
