Recovery Audit Contractor (RAC), MAC, ZPIC & OIG audits cost healthcare practices millions in overpayment demands and penalties. MD Audit Shield builds your defense — before the audit letter arrives.
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.
From routine Medicare claim reviews to OIG fraud investigations, MD Audit Shield covers every audit type that can impact your practice's revenue and reputation.
| Audit Type | Full Name | Primary Focus | Typical Timeline | Risk Level |
|---|---|---|---|---|
| RAC | Recovery Audit Contractor | Overpayments & underpayments in Medicare claims | 120–180 days | Critical |
| MAC | Medicare Administrative Contractor | Medical necessity, documentation, billing accuracy | 30–90 days | High |
| ZPIC / UPIC | Zone Program Integrity Contractor | Fraud, waste & abuse investigations | 90–365 days | Critical |
| OIG | Office of Inspector General | Compliance, exclusions, corporate integrity | 6–24 months | Critical |
| CERT | Comprehensive Error Rate Testing | Random sample review of claim accuracy | 60–120 days | Moderate |
| Pre-Pay | Pre-Payment Review | Documentation review before reimbursement releases | Ongoing | High |
| SMRC | Supplemental Medical Review Contractor | Targeted review of high-volume billing codes | 30–60 days | High |

High-dollar procedures and complex E/M coding in cardiology, oncology, and surgical specialties attract disproportionate RAC scrutiny. We know every documentation requirement for complex cases.
Home health certifications, HCPCS Level II medical necessity, and durable medical equipment documentation are high-frequency RAC targets. Our compliance reviews keep your records airtight.
