# File appeals
> What's appealable in dental and what's benefit design, attachments and narratives as the appeal payload, per-payer appeal routes, deadlines, and tracking win rates by payer and reason.
An **appeal** contests a payer's adjudication decision. Use it when the claim was correct and you believe the payer's decision was not. Strong dental appeals rely on clinical evidence such as radiographs, periodontal charting, and narratives. First confirm that the issue is appealable rather than a rejection, downgrade, or benefit limitation.
## Prerequisites
* The denial is genuinely a denial rather than a 277CA rejection; see [Submit clean claims](/guides/billing/submit-clean-claims)
* The issue is not a downgrade or limitation; see [Denials vs downgrades](/concepts/payments/denials-vs-downgrades)
* The appeal deadline for this payer, recorded
* The 835 showing the denial
* The clinical documentation assembled
## Know what's appealable
This filter matters more in dental than anywhere else, because dental remittances are full of benefit-design reductions that look appealable and aren't:
| Situation | Appealable? |
| ----------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------- |
| **Necessity denial**, such as a crown denied for insufficient documented decay, SRP denied based on pocket depths, or a buildup denied as unnecessary | **Yes.** This is a common dental appeal and requires clinical evidence. |
| **Missing-attachment denial where you have the attachment** | Yes. You may be able to resolve it by supplying the documentation rather than filing a formal appeal. |
| **Timely filing where you filed on time** | Yes, with the acceptance report. See [Beat timely filing limits](/guides/billing/beat-timely-filing). |
| **Payer processing error**, such as a wrong fee schedule, missed COB, or misapplied history | Yes. Aggregate the issue if it is systematic. |
| **Missing tooth clause** where the extraction happened *during* this coverage | Sometimes. Prior records showing the extraction date may defeat the exclusion; verify the plan's clause wording. |
| **Downgrade / LEAT** | **No.** The claim was paid at the alternate benefit. Bill the patient where the contract permits |
| **Frequency limit or exhausted annual maximum** | **No.** Benefit design. Patient responsibility |
| **Waiting period, excluded service** | No, unless the payer applied its own plan terms incorrectly |
A team that appeals downgrades wastes its appeal capacity and trains payers to ignore its letters. Route benefit design to the patient ledger and save appeals for determinations that are actually wrong.
## Know which track you're on
| Type | Track |
| ----------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Commercial, fully-insured** | Payer's internal levels, then state external review |
| **Commercial, self-funded (ERISA)** | Payer's internal levels under ERISA claims procedure; **state external review generally unavailable** |
| **Delta Dental** | The member company that adjudicated the claim. Each of the 39 companies runs its own appeal process; there is no national Delta appeals desk. |
| **Medicaid dental** | The dental benefit administrator's appeal process, as described in its provider manual for your state, followed by the state fair-hearing process where available |
| **Medicare Advantage dental** | The plan's process, then the federal MA appeals track |
**Determine funding status before citing a state statute.** A prompt-pay or external-review argument may not apply to a self-funded ERISA plan. Employer dental benefits can be self-funded even when a carrier's logo appears on the card. See [Payers vs insurance companies](/concepts/payments/payers-vs-insurance-companies).
Traditional Medicare applies to a limited set of dental claims. If you bill crossover work under Part B or DMEPOS, those claims use Medicare's five-level appeals process. See [Bill medical plans for dental work](/guides/billing/bill-medical-for-dental-work) and the [MSO-PC Wiki's appeals guide](https://mso.getlemma.com/guides/billing/file-appeals).
Commercial deadlines are set by contract and vary widely. Some run only 60 or 90 days from the remittance date. Medicaid dental-benefit-administrator deadlines appear in the applicable provider manual and may also be short.
**Record every payer's appeal deadline in your tracking grid** when you sign the contract, not when you need it.
## The payload: attachments and narratives
Dental appeals are decided by dental consultants looking at images. The argument is the documentation:
* **Radiographs**: pre-op x-rays showing the decay, fracture, or bone loss that justified the work. Use diagnostic-quality images that are dated, oriented, and mounted.
* **Periodontal charting**: dated pocket depths and bleeding points for SRP and periodontal surgery
* **Intraoral photos**: fractures and failed restorations that x-rays may understate
* **The narrative**: a few factual sentences from the treating dentist connecting the findings to the treatment, including what was observed and why this procedure was selected
Send attachments through the payer's required channel. Many accept appeal documentation through the same attachment services used for claims. See [Dental attachments](/reference/edi/dental-attachments).
## Anatomy of an appeal letter
Four parts. Keep it to one or two pages.
### 1. Identification
Patient name, member ID, claim number, dates of service, tooth numbers and surfaces, billed amount, denial date, and the **specific CARC and RARC** being appealed. Make it trivially easy for the reviewer to locate the claim.
### 2. The facts
What was done, why, and by whom. Brief and factual. Two or three sentences.
### 3. The argument
Support the argument with a source that matches the issue:
| Denial type | Cite |
| -------------------- | --------------------------------------------------------------------------------------------------------------------- |
| Necessity | The clinical findings (radiographs, charting, photos) against the payer's own published processing or clinical policy |
| Preauthorization | The authorization number and date, or the payer's own retro-auth policy |
| Timely filing | The clearinghouse acceptance report showing the submission date |
| Coding | The CDT descriptor and why it fits the documented procedure |
| Eligibility | The **saved 271** showing active coverage on the date of service |
| Missing tooth clause | The record showing the extraction date fell within this plan's coverage |
Cite the payer's own policy and show how the patient's record satisfies its criteria. For example, identify four-millimeter pockets where the policy requires that depth. Find the current policy on the payer's provider site before drafting the appeal.
### 4. The ask
State it plainly: reprocess and pay the claim at the contracted rate. Include your contact information and any required forms.
### Attachments
Include only what supports the argument: relevant chart notes, images, the eligibility response, submission proof, and the policy excerpt. **Apply the minimum-necessary standard** and avoid sending the entire record when a smaller set proves the point.
## Steps
Consider the dollar amount, the likelihood of success, and whether it's systematic. A $40 denial may not justify the labor, but two hundred instances of the same $40 denial absolutely does, as one aggregated dispute.
Use the required portal, mail, or fax channel. For Medicaid, this is often the dental benefit administrator's portal rather than the state's. An appeal sent through the wrong channel may never be logged.
Portal confirmation, certified mail receipt, or fax confirmation.
Payer, claim, denial reason, appeal date, level, deadline for the next level, outcome, and days to resolution.
Record the next deadline immediately because it runs from the denial at the prior level.
## Track win rates
Appeal outcomes are management information:
| Metric | Tells you |
| ----------------------------------- | ----------------------------------------- |
| Overturn rate **by payer** | Which payers deny claims they shouldn't |
| Overturn rate **by denial reason** | Which appeals are worth filing |
| Average days to resolution by payer | Cash flow planning |
| Appeals filed vs denials eligible | Whether you're leaving money on the table |
A payer with a high overturn rate is denying claims it should have paid. That is a pattern worth raising in contract renegotiation, and in some states worth raising with the insurance regulator.
## Systematic denials get a different treatment
When the same denial recurs across many claims, consider one aggregate submission instead of dozens of individual appeals. Identify the pattern, list the claims, and describe the apparent cause, such as a payer configuration error, misloaded fee schedule, or policy misapplication. Ask the payer to correct the configuration and reprocess every affected claim.
## Verify it worked
* [ ] Downgrades and limitations screened out before anything is appealed
* [ ] Payer funding status determined before choosing the argument
* [ ] Appeal deadline recorded for every payer contract
* [ ] Letters cite payer policy or documentary evidence, with the clinical payload attached
* [ ] Correct form and channel used, including the dental benefit administrator's channel for Medicaid
* [ ] Submission proof retained
* [ ] Every appeal logged with outcome and days to resolution
* [ ] Win rates tracked by payer and reason
* [ ] Systematic denials aggregated rather than appealed individually
## Common failure modes
| Failure | Consequence |
| ------------------------------------------- | --------------------------------------------------------------------- |
| Appealing a downgrade or exhausted maximum | Nothing to overturn; labor wasted; the patient balance ages meanwhile |
| Appealing a 277CA rejection | Nothing to appeal; the claim was never adjudicated |
| Missing the deadline | Unrecoverable |
| Non-diagnostic radiographs | Winnable necessity appeals lost on image quality |
| No policy citation | Low overturn rate |
| Citing state law against a self-funded plan | Undermines the argument |
| Wrong form or channel | Appeal never logged |
| Sending the entire record | Over-disclosure of PHI |
| Not tracking outcomes | No idea which appeals are worth filing |
| Filing individually on systematic denials | Enormous labor for the same result |
