Protect Your Practice From RAC Audits and Compliance Risk
Recovery Audit Contractors and private payers are increasing scrutiny on provider billing every year. If your documentation does not fully support the codes you billed, your practice is exposed to clawbacks, repayment demands, and penalties that can show up years after the original claim was paid.
A proactive medical billing audit is the best defense against this. Rather than waiting for a payer to flag your practice, we review your charts and coding internally to catch problems before they become a liability.
Astral Medical Billing provides medical billing audit services performed by Certified Professional Medical Auditors. We look at both compliance risk and revenue opportunity, because most practices we audit are not just under documented in some areas, they are also leaving money on the table in others.
What Our Medical Coding Audit Services Cover
Compliance Review
We verify that your documentation actually supports the codes that were billed. This includes checking for medical necessity, proper provider signatures, and complete documentation that would hold up under a payer audit.
Coding Accuracy Analysis
Many practices under-code out of caution, billing a lower level visit than what the documentation supports because they are worried about scrutiny. Others over-code without realizing it. We find where your coding sits relative to what your documentation justifies and correct it in both directions.
Evaluation and Management Audits
E/M coding is one of the most commonly audited and most frequently miscoded areas in medical billing. We review your E/M visit levels against the 2026 documentation guidelines to confirm accuracy.
Provider Education and Training
Finding errors is only half the job. We provide detailed reports broken down by provider along with one-on-one feedback sessions so your physicians understand exactly what needs to change in their documentation going forward.
Types of Medical Billing Audits We Perform
- Prospective or Pre-Bill Audits. We review charts before claims are submitted, catching documentation gaps and coding issues before they ever reach a payer.
- Retrospective or Post-Bill Audits. We review claims that have already been submitted and paid, identifying patterns of under-coding or compliance risk across a broader sample of your billing history.
- Focused Audits. When you have a specific concern about a particular code, provider, or payer, we run a targeted audit on that specific area rather than a full practice review.

Frequently Asked Questions About Medical Billing Audit Services
Most practices benefit from an annual comprehensive audit, with focused audits performed more frequently for high-risk areas or after onboarding new providers. Practices in specialties with higher audit scrutiny from payers may want to audit twice a year.
Under-coding means billing a lower level of service than the documentation actually supports, which means the practice is leaving revenue uncollected. Over-coding means billing a higher level than what is documented, which creates compliance risk and potential repayment liability if caught in a payer audit.
In many cases, yes. We commonly find that practices are under-coding visits out of caution, and correcting that brings in revenue that was already earned but never billed for. The exact impact depends on your current documentation and coding patterns.
We document the issue, explain why it is a risk, and provide specific guidance on how to correct documentation going forward. For retrospective findings involving overpayments, we help you understand your obligations for self-disclosure and repayment.
A focused audit on a specific code or provider typically takes one to two weeks. A comprehensive practice-wide audit usually takes three to four weeks depending on chart volume.
Yes. Every audit includes a detailed report and one-on-one feedback sessions with your providers so the findings translate into actual changes in documentation practices.
