Dentovio is an independent publisher — not a payer, the American Dental Association, or any government agency, and it is unaffiliated with the insurers 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. These pages record filing, correction, appeal, records, and recoupment windows as read in each payer's published documents on the last-verified date — and record honestly where no public number exists. Provider contracts override published manuals, editions change, and several payers set different rules per state, network, or program. Educational reference only, not billing or legal advice; confirm the controlling number in your participation contract and the payer's current provider manual before relying on it.

## Direct answer

The initial dental filing window for Delta Dental (deltadentalins.com enterprise) is 12 months — “Generally, claims received more than 12 months after the date of treatment may not be paid” — some programs run shorter windows (the guidance names 90 days for the Texas CHIP program). Reevaluation (one per claim): Delta's public pages describe one reevaluation per claim (“Generally, Delta Dental claims support allows one reevaluation per claim”) with no stated deadline; the commercial appeal window lives in the login-gated Dentist Handbook. Provider contracts and plan documents override published manuals — the contract number controls. Last verified 2026-08-30.

## Filing windows

- **Initial claims:** 12 months — “Generally, claims received more than 12 months after the date of treatment may not be paid” — some programs run shorter windows (the guidance names 90 days for the Texas CHIP program) (Published openly)

## Appeals

- **Reevaluation (one per claim):** No public number — Delta's public pages describe one reevaluation per claim (“Generally, Delta Dental claims support allows one reevaluation per claim”) with no stated deadline; the commercial appeal window lives in the login-gated Dentist Handbook.
  - Route: Provider Tools at deltadentalins.com/dentists; reevaluations go to the original processing Delta Dental member company.

## Verified caveats

- Late-claim patient protection: when a claim is denied for late submission, “the patient is responsible for their coinsurance/copayment portion only” — the late-denied balance cannot be billed to the patient.
- “Delta Dental” is a network of 39 independent member companies. This page covers the deltadentalins.com enterprise — Delta Dental of California and its affiliates, including Delta Dental Insurance Company (AL, FL, GA, LA, MS, MT, NV, TX, UT) and the PA/NY/DC/DE/WV affiliates. Members such as Delta Dental of Michigan, Virginia, or North Carolina publish separate handbooks with their own windows.
- The commercial Dentist Handbook (updated for CDT 2026) is distributed only behind the Provider Tools login (name, TIN, ZIP, license, and NPI required) — no public commercial appeal-deadline number exists.
- Federal programs differ: the public Federal Government Programs Dental Office Handbook 2026 sets a written dispute window of 365 days of the action precipitating the dispute — FEDVIP/VADIP/OCC programs only, not commercial claims.
