The Wound Care Add-On That Grew
A medical reviewer audits a wound care clinic after a data-analytics flag shows that debridement codes are billed on 94% of visits, versus a peer average of 22%. Reviewing 30 charts, the reviewer finds that on 26 visits the notes describe "wound cleaned, dressing changed, no devitalized tissue noted," yet a deep debridement code is billed each time. The clinic's single physician-owner signs all notes and is also the billing entity. When the reviewer requests an interview, the physician says the staff "always do some debridement" and that the notes are "just templates." The clinic received $410,000 in Medicare payments over the audit period.
1. Classify the conduct and identify the indicators that distinguish fraud from error here.

Classification. The pattern points toward fraud, not mere coding error, because it involves a consistent misrepresentation of services on a large share of claims. Key indicators:
- Statistical outlier - 94% versus 22% peer rate is extreme and unlikely by chance.
- Documentation contradicts the code - notes explicitly state no devitalized tissue, which is the clinical prerequisite for a debridement code.
- Template documentation - the physician admits notes are templates, meaning the record does not reflect the actual service.
- Knowledge or reckless disregard - the physician's statement that staff "always do some debridement" shows a belief that any wound care qualifies, which is inconsistent with the code definition and suggests the billing was not based on documented clinical findings.
- Financial incentive - physician-owner is also the billing entity, a structural conflict that raises risk but is not by itself proof.
Error would look different: isolated miscodes, varying patterns, documentation that is merely ambiguous, and corrective action when flagged. A uniform pattern across nearly all visits with contradictory notes supports intentional or reckless misrepresentation.
2. What are the reviewer's reporting obligations, and what should the organization do about the $410,000?
Read the worked answer
Reporting obligations. The reviewer must escalate through the compliance program and, where the organization has identified an overpayment, ensure it is reported and returned. Under the False Claims Act, identified overpayments must be returned within 60 days of identification (the "reverse false claims" provision). If the organization does not act, the reviewer has a duty to escalate to the compliance officer and, potentially, to the board. The reviewer should not conduct the investigation alone or confront the physician without compliance involvement.
The $410,000. The organization should:
- Quantify the overpayment through a statistically valid sample and extrapolation consistent with its compliance plan and payer guidance.
- Refund the identified overpayment and disclose appropriately.
- Consider a self-disclosure (e.g., CMS Self-Referral Disclosure Protocol or the OIG Self-Disclosure Protocol) depending on the facts and counsel's advice.
- Implement corrective action: retire the template, require documentation of specific clinical findings before debridement codes, add a coding edit, and monitor.
The reviewer's role is to document findings objectively, preserve records, and hand off to compliance and legal - not to negotiate with the physician or unilaterally decide the refund amount.
