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.
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 documentation, and prior authorization gaps are the most common triggers.
From routine Medicare claim reviews to criminal 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 | 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 |
Every tool your practice needs to prevent audits, survive them, and recover overpayment demands — backed by AAPC-certified coders and healthcare compliance specialists.
Full-service RAC audit response — from initial overpayment demand through all five levels of the Medicare appeals process, with complete documentation packages.
Proactive internal compliance audit that mirrors what CMS auditors look for — identifying documentation gaps, ICD-10 coding errors, and medical necessity issues before they trigger an external review.
Certified coders review your medical records for documentation completeness — ensuring every claim you submit is fully supported and audit-ready before payers look twice.
When CMS or a contractor demands repayment, we fight back. Our accounts receivable recovery specialists handle overpayment appeals and protect your revenue from auto-deduction.
Every document, communication, and record submission in the MD Audit Shield process runs through AES-256 encrypted, HIPAA-compliant workflows with full Business Associate Agreement coverage.
Expired or missing credentialing is a top RAC audit trigger. Our credentialing team keeps CAQH profiles current, payer enrollments active, and re-credentialing on schedule across all specialties.
From your first free audit risk assessment through ongoing compliance monitoring — a clear, proven process that protects your revenue cycle from day one.
Different specialties face different audit triggers. Our coders and compliance specialists understand the ICD-10, CPT, and medical necessity rules specific to your field — not a one-size-fits-all defense.
Session-based CPT codes (90837, 90834) and modifier requirements are among the most-audited codes by RAC contractors. We specialize in behavioral health documentation standards.
High-dollar procedures and complex E/M coding in cardiology, oncology, and surgical specialties attract disproportionate RAC scrutiny. We know every documentation requirement.
Home health certifications, HCPCS Level II medical necessity, and DME documentation are high-frequency RAC targets. Our compliance reviews keep your records airtight.
Most practices don't know their audit exposure until a demand letter arrives. Our free assessment identifies your top ICD-10 coding vulnerabilities, documentation gaps, and overpayment risk — so you can act before auditors do.
