Dentovio is an independent publisher — not a dental payer, the American Dental Association, X12, a law firm, or any government agency, and it is unaffiliated with the insurers and plans named here. This page was drafted with AI assistance and verified against the primary sources linked here. It has not been reviewed by a credentialed dental billing specialist or an attorney. These generators assemble a letter from selections you make; they do not give legal advice, do not apply legal judgment to your situation, and make no claim about whether an appeal will succeed. Regulations and payer processes are stated as read in the cited documents on the last-verified date; provider contracts and plan documents override published manuals, payers revise their documents on their own schedules, and state routes differ. Educational reference only, not legal, billing, or clinical advice. CDT codes are referenced by number only; CDT codes and descriptors are the property of the American Dental Association, and this page does not reproduce ADA copyrighted descriptors.

## Direct answer

Which letter a dental denial calls for depends on who funds the plan, and the four routes do not share a deadline, an authority, or even a claimant. A self-funded employer dental plan is governed by 29 CFR 2560.503-1: the claimant may demand the claim file free of charge under (h)(2)(iii) with relevance defined at (m)(8), and must be given at least 180 days to appeal under (h)(3)(i), with a de novo review by an independent named fiduciary under (h)(3)(ii) and, on a medical judgment, a consult with a professional trained in the field involved under (h)(3)(iii). A fully insured commercial plan follows the payer's own published process, and those differ sharply — Cigna publishes 180 calendar days nationally and 365 in California, Aetna runs 180 days to reconsideration then 60 to appeal (180 where the issue is medical necessity or experimental criteria), Delta Dental publishes a 90-day claim adjustment before any dispute, and Guardian publishes no appeal form at all. A Medicaid managed care denial belongs to the enrollee: 42 CFR 438.402(c)(1)(ii) lets a provider appeal on the enrollee's behalf only where state law permits and with written consent, on a 60-day clock, and expressly not for continuation of benefits; a provider's own payment dispute is not a subpart F appeal and runs on the contract instead. One guardrail crosses all four: a standalone dental plan is an excepted benefit under 45 CFR 146.145, so no letter should promise federal external review on it, though a state route may exist — Louisiana reaches dental claims over $250, while Illinois excludes dental-only policies outright.

## The four letters

### [ERISA claim file and plan-criteria request](https://dentovio.com/dental-claim-appeal-letters/erisa-claim-file-request/index.html.md)

Plan type: Self-funded employer dental plan (ERISA group health plan)

A claimant under an ERISA group health plan - which includes employer dental benefits - may ask for reasonable access to and copies of all documents, records, and other information relevant to the claim, free of charge, under 29 CFR 2560.503-1(h)(2)(iii). Paragraph (m)(8) defines relevance in four parts: relied upon; submitted, considered, or generated in the course of the determination whether or not relied upon; demonstrating compliance with the administrative processes and safeguards required by (b)(5); and, for a group health plan, a statement of policy or guidance concerning the denied treatment for the claimant's diagnosis whether or not relied upon. Two further entitlements sit in the notice-content paragraphs rather than in (m)(8): the internal rule, guideline, protocol, or other similar criterion relied on, free of charge on request, at (g)(1)(v)(A) and (j)(5)(i), and an explanation of the scientific or clinical judgment for a medical-necessity or experimental denial at (g)(1)(v)(B) and (j)(5)(ii). A group health plan must also identify the medical or vocational experts whose advice it obtained, whether or not it relied on that advice, under (h)(3)(iv). A practice writing in the patient's name needs an authorized-representative designation, not an assignment of benefits: the DOL says an assignment is generally limited to the right to receive payment, and the regulation lets each plan set its own reasonable verification procedure. It prescribes no contents for the designation.

### [ERISA appeal of a self-funded dental plan denial](https://dentovio.com/dental-claim-appeal-letters/erisa-appeal/index.html.md)

Plan type: Self-funded employer dental plan (ERISA group health plan)

An ERISA group health plan - which includes employer dental benefits - must give a claimant at least 180 days after receiving an adverse benefit determination notice in which to appeal, under 29 CFR 2560.503-1(h)(3)(i). The review must be de novo: paragraph (h)(3)(ii) requires a review that affords no deference to the initial determination, conducted by an appropriate named fiduciary who is neither the individual who made that determination nor that individual's subordinate. Where the denial turns in whole or in part on a medical judgment, (h)(3)(iii) requires the fiduciary to consult a health care professional with appropriate training and experience in the field of medicine involved in the medical judgment, and (h)(3)(v) bars using the professional consulted on the initial denial or that person's subordinate. The claimant may submit written comments, documents, records, and other information under (h)(2)(ii), and may obtain the relevant claim documents free of charge under (h)(2)(iii) with relevance defined at (m)(8). The notice on review must state the internal rule relied on, or that a copy is available free on request, at (j)(5)(i), and must give the scientific or clinical judgment explanation for a necessity or experimental denial at (j)(5)(ii). Initial post-service decisions are due within 30 days with one 15-day extension under (f)(2)(iii)(B); pre-service decisions within 15 days with one 15-day extension under (f)(2)(iii)(A). If the plan fails to establish or follow procedures consistent with the regulation, (l)(1) deems the administrative remedies exhausted and the claimant may pursue remedies under ERISA section 502(a).

### [Commercial dental payer reconsideration](https://dentovio.com/dental-claim-appeal-letters/payer-reconsideration/index.html.md)

Plan type: Fully insured or commercial dental plan

A commercial dental reconsideration follows the payer's own published process, and the windows differ sharply. Cigna publishes 180 calendar days from the initial payment or denial notice, extended to 365 calendar days for providers in California, with mailed appeals to the National Appeals Unit at PO Box 188011, Chattanooga TN 37422, or PO Box 188062 for GWH-Cigna and G cards, and arbitration within one year of the final internal decision letter. Aetna runs a two-step ladder: reconsideration within 180 calendar days of the initial claim decision, then appeal within 60 calendar days of the reconsideration decision, extended to 180 days where the issue is medical need or experimental and investigational criteria, filed through Availity or on form GR-69140 to the Provider Resolution Team at PO Box 14020, Lexington KY 40512. Delta Dental publishes a claim adjustment within 90 days, a decision in 30 days, then a provider dispute only after that denial with a written response in 45 working days and a 365-day outer bound, mailed to P.O. Box 997330, Sacramento CA 95899-7330. MetLife's Federal Dental Plan takes a written request with no form, 180 days from receipt of the decision, to P.O. Box 14589, Lexington KY 40512. United Concordia's New Jersey commercial route allows 180 calendar days on the Health Care Provider Application to Appeal a Claims Determination, to PO Box 69420 Harrisburg PA. Guardian takes a written letter of appeal - it publishes no appeal form - and commits to a decision within 60 days, 45 for disability appeals, or less where state law requires. Every one of these payers states that the provider agreement or applicable law supersedes the published guide, so the contract number is the one that controls.

### [Medicaid managed care - enrollee appeal or provider dispute](https://dentovio.com/dental-claim-appeal-letters/medicaid-managed-care-appeal/index.html.md)

Plan type: State Medicaid dental managed care plan (MCO, PIHP, or PAHP)

Federal law gives the appeal to the enrollee, not to the provider. Under 42 CFR 438.402(c)(1)(ii) a provider may request an appeal on an enrollee's behalf only if state law permits and with the written consent of the enrollee, and the same paragraph bars a provider from requesting continuation of benefits. The enrollee has 60 calendar days from the date on the adverse benefit determination notice to file the plan appeal (438.402(c)(2)(ii)); the plan must resolve a standard appeal as expeditiously as the enrollee's health condition requires and no later than 30 calendar days (438.408(a), (b)(2)), extendable by up to 14 calendar days (438.408(c)(1)). A state fair hearing comes only after notice that the plan upheld the determination (438.408(f)(1); 438.402(c)(1)(i)), with a state-set window of no less than 90 and no more than 120 calendar days from the resolution notice (438.408(f)(2)). Where the plan fails the notice and timing requirements the appeal is deemed exhausted and the enrollee may go straight to the fair hearing (438.402(c)(1)(i)(A)). Continuation of benefits is a separate, non-automatic request the enrollee must make by the later of 10 calendar days after the plan sends the notice or the intended effective date, and it requires all five conditions in 438.420(b); if the final decision is adverse the plan may recover the cost of continued services, consistent with the state's usual recovery policy and the contract (438.420(d)). A practice's own payment, pricing, recoupment, or contract dispute is not a subpart F appeal: it follows the managed-care contract and state program rules, whose deadlines differ - Texas HHSC requires the dental contractor to resolve provider complaints within 30 calendar days, and Ohio gives a provider 30 calendar days after exhausting the plan's internal process to request an External Medical Review on a medical-necessity denial.


## Commercial payer routes

| Payer | Product | Published filing window | Decision clock |
| --- | --- | --- | --- |
| Cigna | Commercial dental, national route | 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. | 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. |
| Aetna | Commercial dental, national route | 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. | 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. |
| Delta Dental | Provider claim adjustment and dispute, as published by Delta Dental | 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. | 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. |
| MetLife (Federal Dental Plan) | MetLife Federal Dental Plan (FEDVIP), brochure 02AP-11, 2026 | 180 days from the date of receipt of the decision. The commercial group certificate uses the same 180 days from receiving MetLife's decision. | 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. |
| United Concordia (New Jersey commercial) | Commercial dental in New Jersey | 180 calendar days to file the appeal. | Internal review decision within 30 calendar days. |
| Guardian | DentalGuard group and PPO, plus the Guardian Direct and DHMO routes | 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. | 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. |

Each route is one payer's own published process for one named product. A payer's absence here means it was not verified this pass, not that it publishes nothing.

## State escalation routes, and whether they reach standalone dental

| State | Route | Reaches standalone dental | Window |
| --- | --- | --- | --- |
| Florida | Statutory internal-appeal clock and prompt-pay duties | Conditional | 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. |

| Louisiana | Internal Claims and Appeals Process and External Review Act, R.S. 22:2391 et seq. | Yes | Four months after receipt of the notice of adverse determination or final adverse determination. |
| New York | Utilization review appeals and the Department of Financial Services external appeal | Conditional | 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. |
| New Jersey | Program for Independent Claims Payment Arbitration (PICPA), administered by MAXIMUS for DOBI under HCAPPA | No | 90 calendar days after receiving the carrier's determination on the provider's internal claims-payment appeal. |

## 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.
