A Wake-Up Call: Fraud Charges Are Stacking Up in 2025

This year’s health care fraud enforcement sweep made one thing clear: skin and tissue substitutes are now a frontline focus for federal prosecutors. According to the Department of Justice’s 2025 National Health Care Fraud Case Summaries¹, many recent indictments involve misuse of cellular and/or tissue-based products (CTPs) — particularly in wound care and DME contexts.

Schemes ranged from phantom billing to medically unnecessary applications, often involving improper incentives or misrepresented documentation. The message is loud and clear: enforcement agencies are watching, and wound centers must tighten compliance to avoid falling into the same traps.

CMS Responds: WISeR Model Launches Prior Auth for Skin Substitutes

The Centers for Medicare & Medicaid Services (CMS) has officially launched the Wasteful and Inappropriate Service Reduction (WISeR) Model — a 5-year pilot starting in 2026². It introduces mandatory prior authorization for 17 services most vulnerable to fraud and overuse, including:

Skin and tissue substitutes
Cervical fusion
Epidural steroid injections
Arthroscopy for knee osteoarthritis

Initially rolling out in Arizona, Washington, New Jersey, Texas, and Oklahoma, the WISeR model combines AI-driven analysis with clinician oversight. CMS aims to streamline the process, but also to deny inappropriate claims earlier, reducing the $5.8 billion spent on low-value care in 2022 alone³.

While the model applies only to traditional Medicare (not Medicare Advantage), its arrival signals a growing trend: skin substitutes are no longer being accepted without question.

Why CTPs Are in the Crosshairs

CTPs — often used for diabetic foot ulcers (DFUs) and venous leg ulcers (VLUs) — are a powerful tool in advanced wound care. But when misused, they quickly become a liability. Common pitfalls include:

Incomplete documentation of conservative care
Using CTPs off-label or too early in the healing timeline
Failing to establish medical necessity
Billing for excessive units or unnecessary reapplications

A 2024 MedPAC report noted that Medicare spending on skin substitutes surged to $4.4 billion in 2023, with one product alone accounting for over $1.4 billion in use⁴. In parallel, the HHS Office of Inspector General (OIG) has launched audits targeting Part B skin substitute claims from 2020–2023⁵.

WISeR and Wound Care: What to Expect Next

As WISeR rolls out, wound centers across the country should take this opportunity to prepare — even if their state isn’t part of the pilot. Key signals from CMS show what’s coming:

Increased pre-payment review for high-cost wound therapies
Higher denial rates for skin substitute claims without strong documentation
Growing use of AI to flag aberrant patterns
Rising pressure on vendors and clinicians to justify use with outcomes data

In short: defensible documentation, credentialing, and utilization patterns are no longer optional.

Protecting Your Program: Compliance Is Not Optional

To operate in this evolving landscape, wound care teams must strengthen their internal systems — not just for clinical quality, but for audit readiness.

Here are five areas to focus on now:

Credentialing and Training - Only properly trained and credentialed providers should apply skin subs. Staff should understand both clinical and regulatory requirements.
Smart Patient Selection - Reserve CTPs for patients who truly meet clinical and payer criteria. One-size-fits-all use invites denial.
Thorough Documentation of Medical Necessity - Chart every detail: wound size, response to standard care, offloading, infection status, and more. Use templates or checklists that align with LCDs.
Tracking Outcomes - Monitor healing trajectories and maintain a defensible audit trail. CMS and OIG auditors increasingly expect providers to show evidence of progress — not just procedure codes.
Vendor Accountability - Work only with vendors who respect clinical appropriateness and offer transparent pricing, education, and compliance support.

Final Thoughts: The Future of Wound Care Requires Guardrails

Skin substitutes remain a vital tool — but the stakes are higher than ever. The WISeR model, combined with a wave of federal indictments, shows just how quickly clinical opportunity can turn into regulatory risk.

At Shared Health Services, we’ve built our support model to keep hospital partners ahead of that curve.

Here’s how we help:

We create CTP-specific workflows grounded in CMS guidelines and LCD expectations.
Our billing consultants monitor evolving policy and help apply modifiers and codes accurately.
We offer real-time clinical decision support to align treatment with payer logic and documentation standards.
We track healing outcomes to create clear, audit-ready records respected by reviewers.
We conduct monthly chart reviews and annual compliance audits aligned with RAC, UPIC, and OIG patterns — helping partners proactively surface billing risks, documentation gaps, and payer red flags before they become liabilities.

With more than 25 years of experience, SHS is here to help wound care programs deliver compliant, evidence-based care that improves outcomes and withstands scrutiny.
