ADA fee schedule
The annual benchmark that carriers use to judge whether your dentist's fees are 'reasonable.'
What is the ADA fee schedule?
The ADA fee schedule is a set of benchmark prices published annually by the American Dental Association, derived from a national survey of dentists' actual submitted fees for each CDT procedure code. The survey aggregates fee data by geographic market. PPO carriers use this data as a reference point, anchoring their UCR (usual, customary, and reasonable) calculations to a specific percentile of the ADA survey. A carrier anchoring at the 80th ADA percentile will set its UCR at a level where 80% of surveyed dentists in that market charge that amount or less, meaning 20% of dentists charge more and out-of-network patients face balance billing.
| Carrier anchor | What it means | Effect on you (out of network) |
|---|---|---|
| 50th percentile | UCR set at the market median fee | Lowest allowed amount, highest balance-bill risk |
| 80th percentile | UCR covers 80% of surveyed fees | Moderate allowed amount, common anchor |
| 90th percentile | UCR covers 90% of surveyed fees | Highest allowed amount, lowest balance-bill risk |
How it works
The ADA publishes updated fee survey data periodically. Carriers license this data and blend it with their own claims data to build the UCR tables they apply to out-of-network claims. For in-network claims, the negotiated fee schedule, which may be discounted well below even the ADA survey median, governs instead. The ADA fee schedule is not publicly available without a paid license, and carriers do not disclose which percentile they anchor to.
CDT D2740 (crown). ADA's 2024 survey for your metro area shows: 50th percentile = $1,000, 80th percentile = $1,400, 90th percentile = $1,650. If your carrier anchors at the 80th percentile, the UCR is $1,400. Your dentist charges $1,600, you face a $200 balance bill plus your coinsurance. Your carrier's in-network negotiated rate may be $950, saving $650 vs. the dentist's full charge.
What to watch out for
- The ADA fee schedule is not the same as a carrier's UCR. Carriers use ADA data as an input, then apply their own adjustments and choose their own percentile. Two carriers may use the same ADA data but set very different UCRs, ask your carrier directly what percentile it uses.
- Fee schedules lag the market. ADA surveys are conducted periodically; during inflationary periods, actual dental fees rise faster than survey updates. This means UCRs may be based on dated data, systematically under-compensating providers and increasing patient balance-bill exposure.
Frequently asked questions about the ADA fee schedule
Carriers license ADA survey data and use it, combined with their own regional claims data, to set UCR (allowed amount) tables for out-of-network claims. They select a geographic market and a percentile (typically 80th or 90th) as the UCR anchor. The same procedure may have different UCRs with different carriers even in the same zip code.
The full ADA fee schedule data requires a paid license. However, Fair Health (fairhealthconsumer.org) publishes a free consumer cost estimator that draws on independent claims data and approximates regional UCR benchmarks. Use it to estimate your out-of-network exposure before major procedures.
Yes. In-network fees are contractually negotiated directly between your carrier and the dentist, independent of ADA benchmarks. In-network, the allowed amount is the contracted negotiated rate, a fixed number you can know in advance. ADA UCR concerns only apply when you go out-of-network.
Specialty procedures, implants, complex bone grafts, full-mouth restorations, advanced periodontal surgery, and sedation, most often exceed UCR because specialists' fees outpace general-practice survey data used to set benchmarks. Always get a pre-determination for any specialty procedure.
