Dentovio is an independent publisher — not an insurance carrier, benefits administrator, the American Dental Association, or any government agency, and it is unaffiliated with the payers 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 attorney. Missing tooth clauses, downgrades, and frequency limits are contract terms: each rule here was read in the one named plan document, payer policy, or program manual cited beside it on the last-verified date, and none of them is a payer-wide standard — several of the payers say so in their own words. Plan documents govern, editions change, and a summary is not the contract. CDT codes appear by number only; plain-language names are Dentovio paraphrases and no ADA descriptor text is reproduced. Educational reference only, not legal, benefits, or billing advice; confirm the controlling term in the patient's certificate or policy before quoting a patient or submitting a claim.

## Direct answer

A dental downgrade is the payment of a lower allowance than the service performed, under a plan's alternate benefit provision: where more than one professionally acceptable treatment exists for a condition, the plan pays for the less costly one and the patient may owe the difference. Payers write it under different names — Aetna's Alternate Treatment Rule, Cigna's Alternate Benefit Provision, MetLife's Alternate Benefits, Delta Dental Insurance Company's Optional Services — and Aetna, Cigna, and Guardian all state that the provision varies by employer or plan. Named substitutions read for this page include posterior composite paid at the amalgam benefit (one Guardian Utah plan and one DentaQuest Ohio policy), inlays paid as an alternative benefit of amalgam, a crown paid at a four-surface filling allowance (United Concordia's FEDVIP brief), a fixed bridge paid at the removable partial denture rate (Aetna's published example), and a prefabricated restoration benefited under the composite code where it fails the crown guidelines (Delta Dental Insurance Company's clinical criteria). Two conditions decide most disputes and are missing from most summaries: the downgrade is rebuttable when evidence submitted with the claim explains why the less expensive treatment could not be done, and a participating dentist may bill the patient the difference only after documented advance notice of liability. Downcoding is a different act from a plan-driven alternate benefit — Aetna says so itself — and Medicaid programs generally deny rather than downgrade: Colorado's dental manual has no alternate benefit provision at all.

## What is payer-level here, and what is not

Three payers state an alternate benefit position as their own: Aetna publishes the provision most of its plans contain, United Concordia publishes one for its federal program, and Delta Dental Insurance Company publishes clinical criteria that decide when an alternate benefit may be elected across seven named affiliates. Everything below that level — which substitutions apply, at what allowance, with what patient liability — is written in the plan document, and Aetna, Cigna, and Guardian each say so.

## What the documents say

### The alternate benefit clause, as each document writes it

#### Aetna — Payer-stated policy

Aetna Dental's public claim-submission guidance on downcoding and bundling, which quotes the alternate benefit provision most Aetna plans contain. Document date: Undated web page; read 2026-08-31.

**Trigger:** Two treatments, one condition

Where more than one service can treat a condition, Aetna may authorize coverage only for the less costly one — but only if that service is an appropriate method of treatment in the profession's judgment and meets broadly accepted national standards of dental practice. Aetna's published worked example is a fixed bridge benefited at the removable partial denture rate when a partial would replace all the missing teeth in the arch.

> Alternate Treatment Rule — If more than one service can be used to treat a covered person's dental condition, Aetna may decide to authorize coverage only for a less costly covered service provided that both of the following terms are met: The service selected must be deemed by the dental profession to be an appropriate method of treatment; and The service selected must meet broadly accepted national standards of dental practice

Caveats that travel with this:

- Aetna calls this "the current, most common ABP provision" and says provisions "may vary among employers (and other plan sponsors, such as unions)". Write "the alternate benefit provision most Aetna plans contain", never "Aetna's rule".
- Aetna's own framing separates two things: applying a plan's alternate benefit is not downcoding. Its downcoding definition expressly excludes "the denial or adjustment of claims for covered services in accordance with the terms of a member's dental benefits plan".
- The page is undated — no effective date, revision date, or version number — so any citation needs an access date rather than an effective date.

#### Cigna (one self-funded group booklet) — One named plan

Cigna Dental Preferred Provider Insurance certificate booklet for one self-funded (administrative-services-only) group plan, effective July 1, 2018. Document date: Effective July 1, 2018 (printed June 2018); provision form HC-DEN1 04-10 V1.

**Rule:** Least costly service

Where more than one covered service will treat a condition, payment is limited to the least costly service, provided it is a professionally accepted, necessary, and appropriate treatment. If the member requests or accepts a more costly covered service, the member owes the excess over the least costly amount.

> If more than one covered service will treat a dental condition, payment is limited to the least costly service provided it is a professionally accepted, necessary and appropriate treatment. If the covered person requests or accepts a more costly covered service, he or she is responsible for expenses that exceed the amount covered for the least costly service.

Caveats that travel with this:

- This is one self-funded group's 2018 booklet administered by Cigna, not a Cigna standard. Cigna's own hedge on its employer pages is "Plans may vary" and "Plan benefits will vary based on plan type and what you discuss with your local Cigna Healthcare representative".
- The booklet contains zero CDT codes. Any code-level Cigna downgrade table circulating online is not sourced to a Cigna document.
- The Patient Charge Schedule is a Cigna Dental Care (DHMO) construct. The phrase never appears in this DPPO booklet, so a claim that "the PCS determines the downgrade mapping" conflates two products.

#### United Concordia FEDVIP — Payer-stated policy

United Concordia's FEDVIP benefit brief on the alternate benefit provision, written for federal agency benefits officers. Document date: Undated; server last-modified 2026-02-06. Retrieved 2026-08-31..

**In-network:** Member still owes the difference

Under this provision the plan covers the less expensive treatment available and member coinsurance may still apply. The published example is a cracked tooth that could be repaired with a four-surface filling: if the patient and dentist choose a crown, the plan pays the four-surface filling allowance and the patient pays the difference — even with an in-network provider.

> Should you and your dentist choose the more expensive treatment, you are responsible for the additional charges beyond the allowance for the alternate service, even if using an in-network provider.

Caveats that travel with this:

- The document is a FEDVIP brief end to end. It makes no cross-plan statement, and United Concordia publishes no alternate-benefit page for its commercial lines at all.
- The example says "four-surface filling". It does not say amalgam, and the page contains no inlay, composite, porcelain, or ceramic example.
- The brief's predetermination line is member-facing advice, not a provider submission rule: "If a proposed treatment plan is estimated to cost $300 or more, United Concordia encourages you to ask for a predetermination."
- Undated and unversioned, so the dollar threshold can change silently. Retrieved 2026-08-31.

#### MetLife (PPO plan-summary form) — One named plan

MetLife-authored group dental plan summary, form DN-ANY-PPO-STAND on policy form GPNP99. Document date: MetLife legal ID L0419514058[exp0620][xNM]; © 2018 MetLife Services and Solutions, LLC.

**Rule:** Least costly alternative

Where two or more professionally acceptable treatments exist for a condition, reimbursement is based on the least costly alternative, and a patient who agrees to a more costly treatment carries the additional payment responsibility.

> Alternate Benefits: Where two or more professionally acceptable dental treatments for a dental condition exist, reimbursement is based on the least costly treatment alternative. If you and your dentist have agreed on a treatment that is more costly than the treatment upon which the plan benefit is based, you will be responsible for any additional payment responsibility.

Caveats that travel with this:

- Typical MetLife plan-summary language subject to the group certificate — "In the event of a conflict with this summary, the terms of your insurance certificate will govern."
- MetLife's pre-treatment estimate is a member-facing recommendation, not a requirement: "We recommend that you request a pre-treatment estimate for services in excess of $300." No benefit is forfeited by skipping it, and MetLife's term is pre-treatment estimate, not predetermination.

#### Delta Dental Ins. Co. (one group PPO) — One named plan

Evidence of Coverage for Mississippi State University, Group No. 01125, effective January 1, 2024. Document date: Effective January 1, 2024.

**Term:** Optional Services

This plan's downgrade clause is called Optional Services and sits directly above its frequency limits: where the enrollee chooses a more expensive service, benefits are based on the lower cost of the customary service or standard practice, and the enrollee owes the difference. Its named examples include porcelain crowns on maxillary second and third molars or on any mandibular molar.

> We will base Benefits on the lower cost of the customary service or standard practice instead of on the higher cost of the Optional Service. The Enrollee will be responsible for the difference.

Caveats that travel with this:

- One 2024 group PPO plan for one employer. It is not a Delta Dental national rule, and Delta Dental Insurance Company is a different member company from Delta Dental of Michigan, New Jersey, or Washington.

#### FEDVIP program requirement — Program-wide rule

The 2026 FEDVIP dental brochures, which OPM publishes as each carrier's official statement of benefits. Document date: 2026 plan year.

**Program rule:** ABP required in every plan

In FEDVIP the alternate benefit provision is not optional plan design — the program requires it. Plans must provide an alternate benefit for treatment beyond the least expensive professionally accepted standard of care, with the patient paying the difference. MetLife's brochure adds the sentence that decides most disputes: the dentist may bill the patient the difference even when the service was performed in network.

> The plan must provide an alternate benefit provision for benefits beyond the least expensive professionally accepted standard of care, whereby the patient pays the difference between the covered benefit and the more expensive treatment option.

Caveats that travel with this:

- FEDVIP is an OPM-negotiated program and is not representative of the commercial group market.
- Two conditions travel with any FEDVIP alternate benefit: it is rebuttable with evidence at submission, and a participating dentist may bill the patient the difference only after documented advance notice of liability.

### Substitutions the documents actually name

#### Cigna (one self-funded group booklet) — One named plan

The same 2018 self-funded group booklet — its actual esthetic-crown mechanism. Document date: Effective July 1, 2018; provision form HC-DEX1 04-10 V1.

**Mechanism:** Exclusion, not a code map

On this booklet the esthetic downgrade on posterior crowns is a coverage exclusion rather than a code substitution. Covered crowns are listed only as porcelain fused to high noble metal, full cast high noble metal, and three-fourths cast metallic, and the plan excludes porcelain or acrylic veneers of crowns or pontics on — or replacing — the upper and lower first, second, and third molars.

> porcelain or acrylic veneers of crowns or pontics on, or replacing the upper and lower first, second and third molars

Caveats that travel with this:

- This is a defensible, sourced statement of how an esthetic posterior crown gets reduced on this plan. It is not evidence of any payer-wide code mapping.
- The booklet also documents a predetermination pathway recommended before major treatment and above $300 — the practical answer to a downgrade surprise.

#### MetLife FEDVIP — Program-wide rule

The MetLife Federal Dental Plan (FEDVIP) — MetLife's own FAQ for the program. Document date: Change effective January 1, 2023; FAQ read 2026-08-31.

**Posterior composite:** No amalgam downgrade since 2023

The posterior-composite-to-amalgam downgrade is not a standing MetLife rule. On MetLife's largest published book, it was removed: resin-based composite fillings on posterior teeth and molars no longer receive an alternate benefit of amalgam for dates of service on and after January 1, 2023.

> Note: Resin-based composite fillings on posterior teeth and molars, will no longer receive an alternate benefit of amalgam for dates of service on and after January 1, 2023 as a Class B service.

Caveats that travel with this:

- This is the FEDVIP program. Neither MetLife group plan summary read for these pages contains any composite-to-amalgam rule; on a commercial group plan a downgrade would flow from the general alternate benefit clause on a case-by-case determination.
- Check the date of service against the plan's current rule before quoting a patient. A downgrade rule that was true two plan years ago is not evidence about this claim.

#### Guardian (Utah EHB plan) — One named plan

Utah Essential Health Benefit — Guardian Preventive Plus, both the child (to age 19) and adult (19 and over) benefit sets. Document date: 2021 filing (form IP-DENF-SCH6-21-UT).

**Posterior composite:** Paid at the amalgam benefit

This plan carries three downgrade clauses. Replacing an existing partial denture, full denture, crown, or bridge with more costly units or a different type of unit is limited to the benefit for the unit being replaced. Composite restorations on posterior teeth are limited to the benefit for the corresponding amalgam restoration. On the child plan, that substitution comes with a consent condition.

> Resin (tooth colored) Restorations – Posterior (back) teeth ONLY — Limited to the benefit of the corresponding amalgam restoration; Prior to placement member must be informed and agree to pay the cost difference

Caveats that travel with this:

- The consent sentence is on the child benefit set. The adult set states the amalgam limit without it.
- A 2021 filing with no effective date in the body and no live Guardian page linking it — currency is not established.

#### DentaQuest (Ohio individual PPO) — One named plan

DentaQuest PPO for Individuals and Families, Ohio, Family High Plan policy, effective January 1, 2026. Document date: Effective January 1, 2026; renews annually on January 1.

**Posterior composite:** Amalgam allowance

This policy names its substitutions. Multi-surface synthetic restorations on posterior teeth are treated as an alternate benefit with an amalgam allowance, and the patient is responsible up to the dentist's charge. Inlays are paid as an alternative benefit of amalgam. A general least-costly clause sits behind both.

> If you and your dentist decide to use services that are more expensive than those customarily furnished by most dentists, benefits will be provided towards the service with the lower fee

Caveats that travel with this:

- This is an individual-market Ohio policy with two entirely separate benefit lists, one for covered individuals under 19 and one for 19 and over. State any rule with its age band.
- Periodontal benefits on this policy are "determined according to our administrative Periodontal Guidelines" — an unpublished administrative document that has not been read and must not be characterized.

### When the payer changes the submitted code

#### Aetna — Payer-stated policy

Aetna Dental's public downcoding and bundling guidance. Document date: Undated web page; read 2026-08-31.

**Condition:** Licensed-dentist review

Aetna states it does not automatically change a submitted code to a lower-cost one. A code may be changed when professional review of the charges and the supporting clinical information — radiographs, photographs, periodontal charting, narratives, treatment notes — indicates the original coding may have been inappropriate. A reduction in reimbursement must be based in significant part on review of the individual clinical record by a licensed dentist.

> A submitted code may be changed when a professional review of the submitted charges and supporting clinical information such as x-rays, photographs, periodontal charting, narratives, and treatment notes, indicates that the original coding may have been inappropriate

Caveats that travel with this:

- The licensed-dentist review condition is a quotable protection, and it is the practical hook for a documentation-led appeal.
- Aetna's published triggers are specific: a surgical extraction reduced to a routine extraction where the teeth are periodontally involved with excessive bone loss or exposed roots; fully erupted teeth removed for orthodontic reasons treated as routine removal; an indirect pulp cap on the same date as a permanent restoration bundled into the restoration.
- Procedures here are described in plain language rather than by ADA descriptor text, and Aetna's own definition of downcoding is keyed to the CDT — reduction to a lower-cost code "unless expressly provided for in the CDT Code".

### Reductions that are a fee benchmark, not a substitution

#### Cigna (Pennsylvania individual outline) — One named plan

Cigna Dental Vision 1000 Plan, Pennsylvania individual market, Outline of Coverage. Document date: Policy form INDDENPOL2024PA.DV1000; footer revision stamp DV001 04-2026.

**Benchmark:** Lowest contracted fee

The out-of-network reduction on this plan is a benchmark, not a code substitution: benefits are set against the Primary Schedule, which is the fee schedule with the lowest contracted fees currently accepted by a participating dentist in the area, and a non-participating dentist may charge more, leaving the member balance-billed for the difference.

> The Primary Schedule is the fee schedule with the lowest Contracted Fees currently being accepted by a Participating Dental Provider… Non-Participating Providers may charge You more than this Contracted Fee, which means you will be balanced billed for the difference.

Caveats that travel with this:

- Predetermination on this plan is voluntary and non-binding — "It is not preauthorization of service and is not required… not a guarantee of a set payment" — and is advised above $500.
- An Outline of Coverage expressly subordinates itself to the policy: "This is not the insurance contract and only the actual Policy provisions will control."

### What happens when clinical criteria are not met

#### Delta Dental Ins. Co. clinical criteria — Payer-stated policy

Clinical Criteria for utilization management, scoped on its cover to Delta Dental Premier, Delta Dental PPO (DPO in Texas) and Medicare Advantage for Delta Dental Insurance Company and Delta Dental of California, Delaware, the District of Columbia, New York, Pennsylvania (including Maryland), and West Virginia. Document date: Cover states effective January 1, 2025, pending state regulatory approval; file generated December 2025.

**On criteria failure:** "May elect" an alternate

Failing the clinical criteria does not dictate a downgrade. The governing formula is permissive and recurs at the head of section after section: where a procedure fails the criteria, Delta Dental may elect to benefit an alternate service consistent with the patient's clinical presentation. One code family states the substitution explicitly — a prefabricated restoration that does not meet the crown guidelines is benefited under the appropriate resin-based composite code by surfaces involved.

> A resin based composite restoration that does not meet the clinical guidelines for a crown will be benefited under the appropriate resin based composite code based on the surfaces involved.

Caveats that travel with this:

- That sentence is item 3 under the prefabricated-restorations guidelines for codes D2928–D2934. It is not a rule for laboratory-fabricated crowns.
- Crown eligibility here is not a bare percentage: an anterior tooth needs significant loss greater than 50% and involvement of one or both incisal angles (or the cusp tip on a cuspid); a posterior tooth needs greater than 50% loss including loss or undermining of one or more cusps and a compromised marginal ridge, plus at least one listed finding.
- The cover states the version is effective as of January 1, 2025, pending state regulatory approval, while the file itself was generated in December 2025. Confirm the edition with Delta before keying anything to a plan year.
- The document's own footer disclaims equivalence with the CDT: "There are important differences between Delta Dental's Processing Policies and Procedures and dental plan benefits and the processing policies and descriptors found in CDT."
- It is guidance, not benefits: "Specific care and treatment may vary depending on individual need and the benefits covered under individual contract."

#### Guardian (Michigan DIFS order) — One named plan

A Michigan Department of Insurance and Financial Services external-review Order, File No. 243066-001, adjudicating one member's group-plan crown denial and quoting Guardian's dental necessity criteria. Document date: Order issued February 6, 2026; underlying denial November 27, 2025.

**Outcome:** Denial upheld, no downgrade

When crown criteria fail, some plans pay an alternate benefit and some simply deny. This order is the second case: the regulator upheld Guardian's denial of a $1,204 porcelain crown outright. No alternate benefit, least-expensive-alternative, or downgrade provision appears anywhere in the record.

> In most instances, crowns are benefitted for: (1) Teeth with 50% or more of a cusp/incisal edge or overall tooth structure decayed and/or completely fractured (missing) (2) Endodontically treated posterior teeth, and/or (3) Teeth with a clinical diagnosis of Cracked Tooth Syndrome including documentation of clinical testing and/or symptoms.

Caveats that travel with this:

- The criteria are quoted as the regulator excerpted them. Guardian's own criteria document could not be located on any Guardian-controlled host and carries no version or effective date in the order, so this is never a nationwide Guardian policy we have read.
- The threshold is 50% of a cusp or incisal edge or of overall tooth structure — a per-cusp alternative — and the framing is "in most instances", not a hard gate.
- Guardian's injury definition in the same record excludes damage "which results solely from chewing or biting food or other substances", so a cusp fractured on a popcorn kernel has to rest on the decay or cracked-tooth prongs instead.
- The review was retrospective: the crown was already placed and billed, and the regulator refused expedited handling for that reason. The lesson is a pre-treatment estimate.

### Medicaid and CHIP programs

#### DentaQuest — Colorado Medicaid — Program-wide rule

Health First Colorado dental Office Reference Manual administered by DentaQuest. Document date: Running footer "DentaQuest, LLC July 1, 2026"; quarterly revision cycle.

**Mechanism:** Denial, not downgrade

Medicaid denies where commercial downgrades. This manual has no alternate benefit provision at all — the words downgrade, alternate benefit, least costly, and less expensive do not appear in it. Crown criteria fail where a lesser means of restoration is possible, and the consequence is denial rather than a reduced allowance. The program separately bars denying medically necessary treatment on cost alone, while allowing relative cost-effectiveness among equally effective options to be weighed in prior authorization.

Caveats that travel with this:

- Frequency and coverage exceptions run through EPSDT and stop at 21. For adults there is no prior-authorization exception route: over-limit care becomes member liability with written acknowledgment of financial responsibility.
- An approved prior authorization is not a guarantee of payment, and the manual lists the ways an approved request can still be denied.
- The manual self-stamps proprietary and confidential despite public linking, so it is paraphrased here with no extended reproduction.

#### MCNA (Texas Medicaid and CHIP) — Program-wide rule

MCNA Texas Provider Manual v1.31, effective March 1, 2026. Document date: Effective March 1, 2026 (v1.31).

**Aggregation:** Paid as a full-mouth series

MCNA aggregates radiographs rather than downgrading procedures. Where any combination of intraoral images submitted meets or exceeds the reimbursable value of the comprehensive intraoral series, the claim is processed at the comprehensive-series fee: the total for periapicals and other radiographs cannot exceed the payment for the comprehensive series.

> The fee for a comprehensive series of radiographic images (D0210) will be applied when an office submits any combination of x-ray imaging exceeding the reimbursable value of the comprehensive series (D0210) of radiographic images.

Caveats that travel with this:

- This is the one alternate-benefit-shaped rule in MCNA's Texas documents. The manual contains no general least-expensive-aggregate policy and nothing applying such a rule to specialty referrals.
- MCNA writes Medicaid and CHIP only; it has no commercial book of business.

## Questions that settle a specific plan

### Does the plan contain an alternate benefit provision, and what is it called in this document?

**Why it matters:** The same mechanism is written as Alternate Benefit Provision, Alternate Treatment Rule, Alternate Benefits, Optional Services, and least-costly-service language. Quoting the plan's own heading back at the payer shortens every call.

**Where the answer lives:** The limitations section of the certificate, and the payer's published claim guidance for its general form.

### Which substitutions does the plan actually name — posterior composite to amalgam, crown to a filling allowance, inlay to amalgam, bridge to a partial denture?

**Why it matters:** Plans that name substitutions can be checked in advance; plans with only a general clause decide case by case. Both were read for these pages, and they call for different treatment presentations.

**Where the answer lives:** The covered-services table and the alternate-benefit or optional-services clause immediately around it.

### Is the posterior composite downgrade in force on this plan for this date of service?

**Why it matters:** It is not a fixed rule of the industry. MetLife's federal program removed the amalgam alternate benefit on posterior composites for dates of service on and after January 1, 2023. A downgrade that applied two plan years ago is not evidence about today's claim.

**Where the answer lives:** The current plan year's benefit document, and the payer's own change list for the plan year.

### Is the alternate benefit automatic, or does the payer say it may elect one when criteria are not met?

**Why it matters:** Delta Dental Insurance Company's clinical criteria use the permissive "may elect" formula. Colorado Medicaid has no alternate benefit at all and denies instead. The difference decides whether you are appealing a reduction or a denial.

**Where the answer lives:** The payer's clinical criteria or utilization-management document, at the head of the relevant section.

### Will the payer accept evidence with the claim explaining why the less expensive treatment was not possible?

**Why it matters:** One federal carrier states it will allow the lower-cost alternative unless evidence is submitted with the bill explaining why the cheaper option could not be done. Where that applies, the narrative belongs on the original claim rather than the appeal.

**Where the answer lives:** The claims or dental-review section of the plan brochure or provider manual.

### Can the patient be billed the difference, and does the participating-provider agreement require documented advance notice first?

**Why it matters:** One federal carrier bars a participating dentist from billing the patient unless the patient was notified of the liability before treatment and the notice was documented — and treats the appeal right as forfeited without it. Getting this wrong breaches the provider agreement.

**Where the answer lives:** The general policies section of the plan document and the participation agreement itself.

### For an out-of-network claim, what fee benchmark sets the allowance?

**Why it matters:** One individual plan read for these pages benchmarks to the lowest contracted fee accepted by a participating provider in the area and leaves the member balance-billed. That is a reduction with no code substitution anywhere in it.

**Where the answer lives:** The definitions section — look for the fee schedule the plan calls primary — and the balance-billing paragraph.

### Is this a PPO, a DHMO or DMO, or a Medicaid program?

**Why it matters:** A patient charge schedule is a DHMO construct, not a PPO downgrade mechanism. Medicaid programs generally deny where commercial plans downgrade. Answering with the wrong product's rule is the most common error in this subject.

**Where the answer lives:** The plan name and product line on the front of the document.

### What is the predetermination or pre-treatment estimate threshold, and is the result binding?

**Why it matters:** Thresholds read for these pages sit at $300 and $500, and none of them binds the payer: one plan states in terms that predetermination is not preauthorization and not a guarantee of a set payment. Present it to the patient as an estimate.

**Where the answer lives:** The predetermination paragraph of the plan document, and the payer's provider channel for submitting one.

## Standing constraints

### The contract overrides the manual, the summary, and the payer policy

Every document behind these pages subordinates itself to an instrument we usually have not read. A Cigna outline of coverage states plainly that it is not the insurance contract and only the policy provisions control. An Aetna DMO evidence of coverage says the group agreement must be consulted for the exact terms. Aetna's clinical policy bulletins say they do not constitute a description of plan benefits. MetLife's plan summaries defer to the certificate of insurance. Read the number here as the default in a named document, then confirm it in the contract that governs the claim.

- [MetLife dental PPO plan benefits (association plan, broker summary page)](https://memberbenefits.com/individuals/dental-and-vision/aop-dental-plan-benefits/) — Disclaimer block: "Read your certificate of insurance for details on plan benefits, limitations, and exclusions."

### There is no payer-wide standard, and four payers say so themselves

Guardian states that plan documents are the final arbiter of coverage and publishes no frequency figure at all. Cigna hedges its own numbers with "Plans may vary" and says benefits vary by plan type. Aetna says most of its plans contain alternate benefit language but that provisions may vary among employers and other plan sponsors. Delta Dental of Michigan says that where a program sets its own criteria or other limitations, those apply — refer to the specific plan or office manual. Write "on the plan documented at this citation, the limit is N", never "this payer's standard is N".

### Member advice and provider rules are not the same instruction

United Concordia's alternate-benefit brief is written to members and federal benefits officers: it encourages the member to ask for a predetermination when a treatment plan is estimated at $300 or more. MetLife recommends that the member request a pre-treatment estimate above $300 — its term is pre-treatment estimate, not predetermination, and no benefit is forfeited by skipping it. Cigna's predetermination is expressly voluntary, is not preauthorization, and is not a guarantee of a set payment. None of the three is a claims-processing requirement, and none of them can be restated as a submission rule.

### A downgrade is rebuttable, and the patient is not automatically billable

Two conditions decide most alternate-benefit disputes and are missing from almost every summary of them. First, the downgrade is contestable at submission: one FEDVIP carrier states it will allow the lower-cost alternative benefit unless evidence is submitted with the bill explaining why the less expensive treatment could not be done. Second, billing the patient the difference is conditional: another states that services not meeting accepted standards are not billable to the patient by a participating dentist unless the dentist notified the patient of the liability before treatment and documented it, and that the appeal right is forfeited without that notice. Alternate-benefit determinations are also appealable, in that program, to a binding independent third party.
