The state of dental billing in real numbers, claim denials, days in AR, insurance verification, credentialing and patient payments. Every figure below is linked to its original source, and we label what comes from a primary body versus an industry estimate.
The short version first, so you can quote it. Each card names its source; the detail and full source list follow below.
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.
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.
| Metric | Figure | Source |
|---|---|---|
| In-network claims denied (ACA marketplace, 2023) | ~19% (range 1%–54% across insurers) | KFF, 2025 |
| Out-of-network claims denied (2023) | 37% | KFF, 2025 |
| Claims appealed by consumers | ~1%; 56% of appeals upheld the denial | KFF, 2025 |
| Claims initially denied, one year | $262B of ~$3T submitted (~9% first-pass) | Change Healthcare, 2017 |
| Denied claims that are recoverable | 63%, at ~$118 to rework each | Change Healthcare, 2017 |
| Denials originating at the front end | ~50% (eligibility / registration) | Change Healthcare Index |
| Dental offices reporting more denials in the last 12 months | 78% Estimate | Zentist 2026 survey |
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.
| Benchmark | Figure | Source |
|---|---|---|
| Median days in AR (medical group practices) | 47 days; top performers ~36 or under 30 | MGMA 2024 |
| AR older than 90 days (medical benchmark) | ~13.5%; over 20% signals a problem | MGMA, via industry |
| Dental target for AR over 90 days | Below 5–10% of total AR Estimate | Dental RCM industry |
| Recovery on dental AR past 90 days | ~15–25%; under 50% collection probability Estimate | Dental RCM industry |
| Dental practices reporting 90%+ net collection | 63% Estimate | Zentist 2026 survey |
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.
This is the strongest dental-specific data in the report, and the least surfaced. The CAQH Index tracks dental administrative transactions directly.
| Metric | Figure | Source |
|---|---|---|
| Dental eligibility & benefit verification spend (2023) | $2.1B, up 15%, largest dental admin category | CAQH Index 2024, via ADA |
| Savings available from automating verification | $580M (up 7%) | CAQH Index 2024, via ADA |
| Automation avoided in US healthcare admin spend | ~$222B in the year measured (+15%) | CAQH Index 2024 |
| Automation posture: dental vs medical | Dental lags medical on every electronic transaction CAQH tracks | CAQH Index 2024 |
| Denials tied to eligibility / authorization (healthcare range) | 35–60% Estimate | RCM industry |
Credentialing figures are all industry estimates, no association or government body publishes a standard timeline, so every number here is labeled as an estimate.
| Metric | Figure | Source |
|---|---|---|
| Commercial payer credentialing time | 90–120 days (Medicare ~60–90) Estimate | Credentialing industry |
| Enrollment applications with errors / omissions | Over 85% Estimate | Credentialing industry |
| Revenue lost to a 120-day credentialing delay | ~$30k–$122k per provider, usually unrecoverable Estimate | Credentialing industry |
| Revenue lost to billing inefficiencies (denials, AR, verification) | 10–15% of annual revenue Estimate | Dental RCM industry |
| Typical outsourced dental billing cost | 4–10% of collections, or ~$4–$12 per claim Estimate | Dental RCM industry |
Where the money comes from is shifting toward the patient, while the industry consolidates. Both change how billing has to be run.
| Metric | Figure | Source |
|---|---|---|
| US dental services spending (2024) | $189B, +4% real, 3.6% of health spending | ADA HPI / CMS NHE, 2026 |
| Dental spend growth by payer (2023→2024) | Out-of-pocket +3.3%, private insurance +2.3%, government +9% | ADA HPI / CMS NHE |
| Average family deductible (2024) | $4,063, up from $2,640 in 2014 | KFF EHBS |
| Self-pay-after-insurance share of bad debt (2021) | ~58%, up from ~11% in 2018 | Kodiak / Crowe |
| Dentists working in the US (2024) | 202,485 | ADA HPI |
| DSO-affiliated dentists (2024) | 16.1% (27% of new dentists), up from 7.4% in 2015 | ADA HPI, 2025 |
| Dentists who are practice owners (2023) | 72.5%, down from 84.7% in 2005 | ADA HPI |
We would rather cite a real number with a caveat than a clean number with no source. Three things worth knowing:
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.
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.
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.
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.
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.
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.
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.
