How a Nationally Recognized Peer Review Overturned a Multi-Million-Dollar UPIC Audit Determination
When an independent practice receives a multi-million-dollar audit demand, the stakes are immediate and existential. One wound therapy practice turned to Acuvance Coker for an objective, specialist-led review that gave it the evidence it needed to fight back and prevail.
An independent wound therapy practice received a UPIC letter demanding repayment of approximately $5 million, based on a Medicare Administrative Contractor audit of roughly 50 patients who had received biologic wound grafting for lower-extremity wounds, including diabetic foot ulcers, venous leg ulcers, and wounds in other locations, such as the sacrum. The practice believed it had followed Local Coverage Determination criteria and billed appropriately, but needed independent, credentialed validation to support an appeal.
The financial exposure was severe enough to threaten the practice's viability if the full payback demand stood. LCD criteria for biologic wound grafting are narrow and specific, covering only chronic wounds of venous or diabetic origin, leaving little room for ambiguity in either direction. Each patient had multiple grafting applications over time, sometimes ten or more per wound, so the actual volume under scrutiny ran into the hundreds of individual applications rather than a simple patient count. To make the appeal credible to the MAC, the practice needed a reviewer with specific, current expertise in biologic wound grafting, not a generalist.
Acuvance Coker conducted a comprehensive peer review of every case under audit, engaging a nationally recognized specialist reviewer to independently validate medical necessity against LCD criteria, and used the findings to build the practice's appeal.
The reviewer was not a generalist wound care physician. He was a nationally recognized podiatrist actively using biologic wound grafting in his own practice, which gave the review both procedural credibility and current clinical relevance. Our approach followed a consistent evidentiary hierarchy: we first compared the care to the applicable coverage determination, then to published evidence-based literature when no coverage determination existed, and finally to the Medicare definition of reasonable and necessary care when neither was available. That structured, defensible methodology, not just a favorable opinion, is what gave the appeal its weight with the MAC.
Approach
- Step 1Assess the Audit Scope and Regulatory Exposure
We reviewed the UPIC letter and the full scope of the MAC's audit, including the patient population, the specific procedures under scrutiny, and the payback amount demanded, to understand exactly what needed to be defended and against what standard. - Step 2Engage a Procedure-Matched Specialist Reviewer
We engaged a nationally recognized podiatrist with current, hands-on expertise in biologic wound grafting and deep familiarity with the applicable LCD criteria, ensuring the review would carry weight with the MAC as a genuine clinical peer opinion. - Step 3Conduct a Comprehensive Case-by-Case Review
The reviewer examined every audited case in full, including every wound and every grafting application, not just a sample, so the appeal rested on complete documentation rather than selective evidence. - Step 4Apply a Structured Evidentiary Hierarchy
For each case, we compared the care delivered to the applicable Local or National Coverage Determination first. Where no coverage determination existed, we turned to published, evidence-based literature. Where neither was available, we applied the Medicare definition of reasonable and necessary care, so every determination had an objective basis rather than relying on judgment alone. - Step 5Validate Medical Necessity and Documentation Adequacy
The reviewer determined that the biologic wound grafting was medically necessary and not experimental in every case reviewed, and that the practice's documentation, including product usage and waste tracking, was appropriate and supported the care delivered. - Step 6Build and Submit the Appeal
We used the review findings to build a comprehensive report submitted to the MAC in defense of the care rendered, giving the practice an evidence-based appeal rather than a general objection to the audit findings.
The practice now has a resolved audit outcome rather than an open existential financial threat. Rather than accepting a payback demand that would have jeopardized the business, the practice used a rigorous, criteria-based clinical review to challenge nearly the entire audit finding and prevailed on all but one case.
What made this possible was pairing Acuvance Coker's structured evidentiary methodology with a specialist reviewer whose clinical credibility matched the exact treatment under scrutiny. Rather than arguing the audit was wrong in general terms, the appeal demonstrated, case by case, that the care met the applicable coverage criteria.
For any practice facing a UPIC or MAC audit demand, the lesson is the same: a payback letter is not a final determination. A comprehensive, criteria-based peer review, conducted by a reviewer with current expertise in the exact treatment under audit, can materially change the outcome, even when the initial demand is severe.
