What Is a Dental Billing Audit?
A dental billing audit is a structured review of how your practice codes, bills and collects for the treatment it provides. It compares what was documented in the clinical record with what was billed, looks at what happened to those claims after submission and examines the reports that show where money is being lost: denials, write-offs, adjustments and aging A/R.
Most practices know that something isn't right — collections feel low compared to production, or the same denials keep returning — but don't know where to start. Provider Concerns' dental billing audit answers that question with specifics: which procedures, which payers, which steps in the process and roughly how much each issue is worth.
What Our Dental Billing Audit Reviews
Coding accuracy and missed charges
We review a sample of patient visits, comparing clinical notes, charting and radiographs with the procedures that were billed. Common findings include:
- Procedures performed but never charted or billed, such as fluoride varnish (
D1206) or core buildups (D2950) - Periodontal patients billed with adult prophylaxis (
D1110) instead of periodontal maintenance (D4910), or the reverse - Evaluations and radiographs coded at a lower level than documented
- Missing surfaces, tooth numbers or quadrants that cause underpayment or denial
- Documentation that doesn't support the code billed — a compliance risk as well as a revenue one
Denial patterns
We categorize denials by payer, procedure and reason over a recent period to show which denials repeat and which step of the process causes them.
Fee schedules and write-offs
We compare your office fees and contracted PPO fee schedules, review whether payers are paying the agreed rate and break down write-offs and adjustments by type to separate legitimate contractual write-offs from avoidable losses.
Front-desk and A/R processes
- How and when insurance is verified
- How long completed procedures wait before claims are sent (claim lag)
- How attachments and narratives are handled
- How quickly payments are posted and denials followed up
- How old the insurance and patient A/R is
Common Findings and Their Fixes
| Finding | Typical cause | Fix in the action plan |
|---|---|---|
| Recurring frequency denials | Benefit history not checked before the visit | Full breakdown verification for every scheduled patient |
| Crowns and SRPs pending for weeks | Missing narratives, x-rays or perio charts | Attachment checklist per procedure type |
| Write-offs higher than expected | Underpayments posted as contractual adjustments | Allowed-amount review during payment posting |
| Large 90+ day A/R | No consistent follow-up schedule | Weekly aging workflow with documented next steps |
| Fees below most PPO allowances | Office fee schedule not updated in years | Fee schedule review and update |
| Claims paid to the wrong provider | Credentialing or NPI mismatches | Credentialing cleanup and NPPES/CAQH alignment |
What You Receive
The audit ends with a written report and a walkthrough call with your team. The report is designed to be used, not filed away.
- Executive summary — the most important findings on one page
- Detailed findings — each issue with examples, the cause and an estimated revenue impact
- Compliance notes — documentation and coding risks that should be addressed
- Prioritized action plan — fixes ranked by impact and effort, with who should own each one
- Recoverable revenue list — claims that may still be correctable or appealable within payer deadlines
When Should a Dental Practice Get a Billing Audit?
- Collections are noticeably lower than production after adjustments
- Denials or "pending" claims are increasing
- Insurance A/R over 90 days keeps growing
- There's been turnover on the billing or front-desk team
- You're switching billing companies or practice management systems
- You're buying, selling or merging a practice and need to understand its revenue cycle
- It has been more than a year since anyone reviewed coding against documentation
An audit is also a good starting point before outsourcing. It gives you and your billing partner a clear baseline, so improvement can be measured.
