Claim denials

Claim denial rates and rework cost

Denials are the biggest single leak in dental revenue, and the most misreported number in the industry. Here is what the primary data actually says.

There is no authoritative "dental claim denial rate"

No primary body publishes a dental-specific denial rate. Vendor blogs cite 15%, 19.3%, and 20% interchangeably with no source. The defensible anchors are the ACA marketplace data (about 19% of in-network claims denied in 2023, per KFF) and the healthcare-wide first-pass estimate of about 9% (Change Healthcare). Treat any exact "dental denial rate" as an estimate.

Days in AR and aging benchmarks

The honest caveat up front: no primary body publishes a dental-specific days-in-AR figure. The credible anchor is MGMA's medical group data; dental targets below are widely used industry rules of thumb.

Note: the "dental" AR figures above are vendor-supplied rules of thumb, not primary research. We flag them as estimates rather than pass them off as measured data, because most sources that rank for this term quote MGMA's medical numbers as if they were dental.

Insurance verification

Eligibility and benefit verification

This is the strongest dental-specific data in the report, and the least surfaced. The CAQH Index tracks dental administrative transactions directly.

Credentialing figures are all industry estimates, no association or government body publishes a standard timeline, so every number here is labeled as an estimate.

Patients & industry context

Patient payments and the dental market

Where the money comes from is shifting toward the patient, while the industry consolidates. Both change how billing has to be run.

How to read this

Methodology and honesty notes

We would rather cite a real number with a caveat than a clean number with no source. Three things worth knowing:

Primary vs estimate

Figures marked Primary come from KFF, the CAQH Index, ADA Health Policy Institute, CMS, MGMA, or Change Healthcare's claims analysis. Figures marked Estimate come from RCM vendors or surveys and should be read as directional.

The dental data gap

Dentistry lacks a primary-sourced denial rate and days-in-AR benchmark. Where only medical data exists (MGMA), we say so rather than relabel it as dental. Anyone quoting an exact "dental denial rate" or "dental days in AR" from a primary body is almost certainly citing a vendor estimate.

We dropped two figures that circulate widely but do not hold up: the claim that "86–90% of denials are preventable per KFF" (KFF does not publish it), and hard counts of "US dental practices" that trace to no verifiable source.

FAQ

Dental billing statistics, answered

What is the dental claim denial rate?

There is no authoritative dental-specific denial rate. The most credible anchors are the ACA marketplace data, where insurers denied about 19% of in-network claims in 2023 (KFF), and healthcare-wide first-pass denial estimates of roughly 9% (Change Healthcare). Vendor figures of 15–20% for dental are unsourced estimates.

What is a good days-in-AR benchmark for a dental practice?

No primary body publishes a dental-specific figure. The closest benchmark is MGMA's medical group data, median around 47 days with top performers under 30. Most dental billing teams aim to keep AR over 90 days below 5–10% of total AR.

How much does dental insurance verification cost the industry?

Dental eligibility and benefit verification spending rose 15% to $2.1 billion in 2023, the single largest category of dental administrative spend, per the CAQH Index 2024. An estimated $580 million in savings is available from automating manual verification.

How long does dental provider credentialing take?

Commercial payer credentialing typically takes 90–120 days and Medicare roughly 60–90 days, per credentialing industry estimates. Most payers offer no retroactive billing window, so revenue lost during the gap is usually unrecoverable.

How large is the US dental market?

US spending on dental services reached $189 billion in 2024, about 3.6% of total national health spending, per ADA Health Policy Institute analysis of CMS National Health Expenditure data.
