How long do I have to appeal a dental claim denial?
Most published dental appeal ladders run a 180-day first level, a 30 to 60 day second level, then an external review. Aetna states one level.
A dental appeal is a ladder, not a letter, and the rungs have their own clocks. The common shape across published carrier and public-programme appeal procedures is a first-level appeal filed within roughly 180 days of the remittance, a second level within 30 to 60 days of the first decision, and then some form of external or independent review. Aetna is the national outlier and says so in one sentence: one level of appeal. Medicaid and Medicare products sit on their own rules — tighter filing windows, faster decisions, and a State Fair Hearing tier that commercial plans have no equivalent of. This article states no appeal success rate for any carrier: none of the published carrier or programme documents states one, and we have not measured it, so there is no measured table in this article.

Two sentences from those documents deserve reading in full. Aetna's, on structure, from its Provider and Behavioral Health Manual, January 2026:
"The complaint and appeal process has one level of appeal"
And Liberty's, on what an incomplete appeal costs, from the Liberty Dental Plan National (All States) Provider Reference Guide 2025:
"In the event an amended provider dispute with the missing information is not received, Liberty will uphold the initial decision and consider the provider dispute process completed."
Why it depends on the contract
The product, not the carrier, sets the window. One insurer commonly runs several different ladders — commercial, Medicare Advantage, Medicaid, federal — with different clocks and different addresses. Delta Dental's New Jersey book gives 30 days for an informal re-review, its Colorado Medicare Advantage manual 60 calendar days for a reconsideration, its federal programmes handbook 365 days for a provider dispute, and its Healthy Michigan Medicaid book 60 days from the EOB.
State law rewrites the national default. Cigna's own guide runs a national default and then carves out Arizona at 365 days with two levels, California at 180 days with one, and New Jersey at 90.
Some rungs cost money to climb. Delta Dental of New Jersey's third tier is external arbitration with the dentist paying half the fee, and TennCare Adult's independent review costs $750, refunded only on a win. Both belong in the decision about whether the claim is worth the climb.
Grievance and appeal are different filings. Liberty separates a grievance — dissatisfaction about service, operations or network matters — from a payment dispute, which is the one that can change money. Filing the first when you meant the second loses the window on the second.
What to do
- Read the deadline off the remittance and the provider agreement for that specific product, not off the carrier's name.
- Diary the first-level deadline the day the denial arrives, and the second-level deadline the day the first decision arrives. The second clock is usually much shorter.
- File the complete packet at the first level. Several carriers close the dispute rather than return it when something is missing.
- Ask for the expedited track when treatment cannot wait — several plans decide urgent appeals in 72 hours.
- On a public programme, remember the tier commercial plans do not have: a State Fair Hearing, usually filed 90 to 120 days after the plan's final decision.
- Check whether the denial belongs in a dispute lane rather than an appeal lane before filing. Timely-filing denials are the usual case.
