Understanding Billing Audit
What is a Medical
Billing Audit?
A billing audit is a systematic review of your practice's claims, coding, and documentation to identify errors, compliance issues, and revenue leakage — before payers or regulators find them first.
Why Every Practice Needs an Audit
Most healthcare providers lose 5–15% of their annual revenue due to undetected billing errors. A professional audit catches these issues and turns lost revenue into recovered dollars.
- Undetected coding errors lead to claim denials and underpayments
- Compliance gaps expose your practice to audits and penalties
- Revenue leakage silently costs practices thousands monthly
- Upcoding or downcoding risks OIG and payer scrutiny
- Regular audits improve first-pass claim acceptance rates

What Audits Reveal
Where Your Practice is Losing Money
Most providers don't know they're losing revenue every month. HNA's billing audit finds exactly where your money is going — and stops the bleeding permanently.
Most Practices Lose 15–25% of Annual Revenue to Billing Errors
Coding mistakes, compliance gaps, and missed charges silently drain revenue — most providers never realize it until an audit uncovers the truth.
