Understanding the Threat

What Is a RAC Audit — and Why Your Practice Is at Risk

A Recovery Audit Contractor (RAC) is a CMS-authorized program that reviews paid Medicare and Medicaid claims for billing errors, coding inaccuracies, and overpayments — then demands repayment with penalties.

RAC auditors work on contingency — they earn a percentage of every dollar they recover. That creates aggressive, targeted audits even when your practice did nothing intentionally wrong. Incorrect ICD-10 coding, missing medical necessity documentation, and prior authorization gaps are the most common triggers in 2025.

⚠️
Automatic Overpayment Demands
When a RAC identifies a billing error, CMS issues an overpayment demand with a strict 120-day repayment window. Without a formal appeal, the amount is auto-deducted from your future Medicare payments.
🛡️
MD Audit Shield: Proactive Defense
We strengthen your documentation, ICD-10 coding accuracy, and compliance posture before federal auditors look — and fight every overpayment demand that arrives.
How a RAC Audit Unfolds
1
Automated Claim Screening
RAC uses data mining algorithms to flag claims with billing patterns, high-dollar codes, or outlier frequencies compared to peers in your specialty.
2
Medical Record Request (ADR)
You receive an Additional Documentation Request for supporting medical records within 45 days — failure to respond triggers automatic denial.
3
Overpayment Determination
If records are missing or don't support the billing code, an overpayment demand is issued. CMS begins recoupment after 120 days.
MD Audit Shield Appeal
We compile your complete defense package and file formal appeals through all five Medicare levels — recovering the majority of challenged demands.

Common Questions

RAC Audit Defense — Frequently Asked Questions

What is a RAC audit and how does it work?
+
A Recovery Audit Contractor (RAC) is a CMS-authorized program that reviews paid Medicare and Medicaid claims for billing errors, incorrect ICD-10 coding, and overpayments. RACs work on contingency — they keep a percentage of every overpayment they recover, which drives aggressive auditing. When an error is found, CMS issues an overpayment demand with a 120-day repayment window. Start your free RAC audit assessment →
What is the difference between a RAC, MAC, ZPIC, and OIG audit?
+
RAC (Recovery Audit Contractor) focuses on retrospective overpayment recovery from paid Medicare claims. MAC (Medicare Administrative Contractor) handles ongoing claims processing and medical necessity reviews. ZPIC/UPIC investigates suspected fraud, waste, and abuse — often triggering payment suspension. OIG handles criminal and civil compliance matters. MD Audit Shield provides defense against all four audit types.
How long do I have to appeal a RAC overpayment demand?
+
You have 120 days from the initial overpayment determination to file a Redetermination (Level 1 appeal). The full Medicare appeals process has five levels: Redetermination, Reconsideration by a Qualified Independent Contractor, ALJ Hearing, Medicare Appeals Council, and Federal District Court. As of FY2024, average ALJ hearing wait times have decreased to approximately 71 days. Our team manages all five appeal levels and can request recoupment suspension to pause auto-deduction from Medicare payments during the process.
What triggers a RAC audit for my practice?
+
Common RAC audit triggers include: high-frequency use of specific CPT codes compared to peer practices, ICD-10 coding inconsistencies, missing or incomplete medical necessity documentation, unbundling of CPT codes, upcoded E/M levels, expired physician credentialing, high rates of certain procedures in your specialty, and telehealth billing compliance issues — a growing focus area in 2025. Our free audit risk assessment identifies your specific exposure before auditors do.
Do you provide RAC audit defense in Georgia?
+
Yes. Pro Health Care Advisors is headquartered in Cumming, Georgia and provides full RAC audit defense, Medicare compliance, and medical billing services throughout Georgia — including Atlanta, Alpharetta, and Roswell — and we serve healthcare practices across all 50 US states.
Is the MD Audit Shield process HIPAA-compliant?
+
Yes. Every document, record, and communication in the MD Audit Shield process uses AES-256 encrypted workflows. We execute Business Associate Agreements (BAAs) with every client and follow strict HIPAA-compliant data handling protocols throughout the audit defense process. See our full HIPAA compliance details →
Can you help recover revenue from denied Medicare claims?
+
Absolutely. Our accounts receivable recovery and Creative Collection Solutions team identifies aging AR, denied claims, and underpaid reimbursements — then files appeals and pursues recovery with proactive payer follow-up. Most practices recover significant revenue from claims they assumed were uncollectable.
What new RAC audit focus areas should practices be aware of in 2025?
+
In 2025, CMS has approved 20 new RAC audit topics, with increased focus on telehealth billing documentation, clinical diagnostic laboratory tests, high-cost specialty procedures, and home health certifications. Sample sizes for record reviews have also increased significantly. MD Audit Shield tracks all new CMS audit topics and proactively updates your compliance posture to address emerging focus areas before they impact your practice.
