A wound care self audit means pulling a sample of your own charts and reviewing them the way a Medicare Administrative Contractor or Unified Program Integrity Contractor would, before that contractor does it for you. The exercise has three parts: drawing a statistically valid random sample of claims, applying the Local Coverage Determination documentation elements to each one, and quantifying what an extrapolated demand would look like across the full lookback period. The audit's findings also start a clock. Under the federal 60-day overpayment rule, identifying an overpayment and sitting on it is its own source of liability.

Building a Sample That Actually Predicts Your Exposure

A self audit is only useful if the sample mirrors how a contractor would build one. CMS directs contractors to use probability sampling reviewed by a statistician, and the free RAT-STATS tool the Office of Inspector General publishes for that purpose is available to providers too. A defensible sample pulls claims at random across the review period, not the practice's own choice of dates, and applies the same checklist a MAC reviewer applies: a qualifying diagnosis, wound measurements tied to the date of service, and, for repeat debridement or skin substitute applications, documented medical necessity for continuing the treatment.

Quantifying the Exposure Before It Is Extrapolated

Once the sample is reviewed, the error rate does the rest of the work. If a percentage of sampled claims fail the LCD's documentation standard, a contractor applying that rate across the full lookback period turns a handful of denied claims into a six or seven figure recoupment demand. Running that extrapolation internally converts a vague sense that some charts are thin into a specific dollar figure the practice can act on. A signature log that cannot confirm who treated the patient and when undermines every claim tied to that provider, exactly the kind of finding that moves the error rate the most.

An internal sample that finds the same error rate a contractor would find is not a compliance exercise. It is a preview of the recoupment demand, quantified while the practice still controls what happens next.

A Self Audit Rarely Stays Isolated

A finding in a debridement or skin substitute sample is the same finding a contractor is already looking for. UPIC Audits of Wound Care Practices: What Triggers Them covers the referral patterns that open a government review, and Wound Care LCD Compliance walks through the same documentation standard a self audit should be built against.

Overpayment or Potential Fraud: The Disclosure Fork

What a self audit turns up determines where it goes next. A billing mistake or documentation gap with no knowing conduct behind it is an overpayment, and Medicare's 60-day rule, codified at 42 U.S.C. Section 1320a-7k(d), requires the provider to report and refund it within 60 days of identifying it, typically through the Medicare Administrative Contractor's voluntary refund process. A pattern suggesting knowing conduct is instead a candidate for the OIG Self-Disclosure Protocol, built for potential fraud and kickback violations, not mere billing errors, which suspends the 60-day clock while the disclosure is under review. Sorting a finding into the correct track is a legal judgment, not an accounting one.

The 60-Day Clock and Reverse False Claims Exposure

Retaining an identified overpayment past the deadline can itself violate the False Claims Act's reverse false claims provision, which reaches a knowing and improper avoidance of an obligation to pay money to the government. A provider has identified an overpayment once it has actual knowledge of it or acts with deliberate ignorance or reckless disregard toward it, and the exposure includes treble damages and per-claim penalties layered on the original recoupment. A self audit that finds a real error and sits on it does not preserve the status quo, and providers preparing for CMS prepayment review carry the same documentation exposure the self audit was built to catch.

Why Early Legal Counsel Is Critical

It is critical that wound care providers retain experienced healthcare defense counsel before conducting a self audit, not after it turns up a finding. Early legal intervention can structure the sample and the review under attorney-client privilege, correctly classify a finding as an overpayment or a disclosure candidate, and manage the 60-day clock once it starts. Delaying representation can turn a routine chart review into an admission the practice cannot walk back.
