OIG Work Plan 2026: Wound Care Audit Priorities

OIG Work Plan 2026: What Wound Care Practices Need to Know Now

The Office of Inspector General publishes an annual Work Plan that signals where its audit and enforcement energy will focus across Medicare and Medicaid. For wound care practitioners, the 2026 Work Plan is not background reading — it is a roadmap of exactly where your billing will be scrutinized. Understanding the OIG's current audit priorities and aligning your documentation and compliance workflows to those priorities can be the difference between a clean audit and a recoupment demand that unravels months of revenue.

This guide covers the wound care–specific areas the OIG has flagged for 2026, the documentation gaps that draw the most attention, and the practical steps mobile and independent wound care practices can take to reduce their exposure.

What the OIG Work Plan Actually Is

The OIG Work Plan is a public document updated throughout the fiscal year. It identifies specific Medicare and Medicaid program areas where the OIG's Office of Audit Services, Office of Evaluations and Inspections, and Office of Investigations plan to focus resources. Items on the Work Plan may result in formal audits, data analysis, or published reports — any of which can generate referrals to the Centers for Medicare and Medicaid Services (CMS) for payment recovery or policy changes.

For wound care, the Work Plan matters for two reasons. First, items that appear on the Work Plan often precede increased scrutiny by Recovery Audit Contractors (RACs) and Targeted Probe and Educate (TPE) programs. Second, OIG findings from prior years tend to repeat — if the OIG identified problems with skin substitute billing in a prior cycle, expect continued attention until the error rate drops to an acceptable level.

Skin Substitute Claims Under Intensified Review

Skin substitutes represent one of the highest-cost categories in outpatient wound care, and the OIG has consistently identified concerns with whether claims meet LCD medical necessity criteria and whether the products billed match what was actually applied. The 2026 Work Plan continues this focus with particular attention to:

Claims where the HCPCS Q-code billed does not correspond to the product dispensed or documented in the medical record
Applications performed before the required conservative treatment period is documented as completed
Claims lacking wound measurement documentation to support the units billed, since reimbursement is tied to surface area
Multiple Q-code claims for the same patient where the medical record does not reflect distinct product applications on distinct wound sites

The flat-rate reimbursement model CMS implemented for skin substitutes in 2026 has changed how practices structure these claims, but it has not reduced OIG attention — it has shifted it toward whether the flat-rate product qualifies under the applicable LCD at all.

Debridement Upcoding and Code Escalation

Debridement is the second major target area. The OIG has flagged billing patterns where excisional debridement codes (CPT 11042–11047) are billed when the clinical record supports only selective debridement (CPT 97597–97598). The distinction matters because excisional debridement requires removal of tissue down to viable tissue, which must be documented with operative detail that selective debridement notes typically lack.

Red flags that draw OIG and RAC attention in this area include:

Consistent use of 11042/11043/11044 with no surgical documentation to support the depth of debridement
Escalating code levels across sequential visits without corresponding clinical deterioration to justify deeper tissue involvement
Billing for debridement on wounds that documentation describes as healing or improving, with no clinical rationale for the procedure on that visit

This is an area where the gap between what clinicians do and what documentation reflects creates the greatest risk. If selective debridement was performed, bill selective. If excisional was performed, the note needs to support it in explicit clinical terms — tissue removed, depth reached, condition of the wound bed post-debridement.

Negative Pressure Wound Therapy (NPWT) Durable Medical Equipment

The OIG continues to review NPWT billing, particularly for home-based portable devices billed through durable medical equipment suppliers. The audit focus includes:

Whether the ordering provider documented medical necessity consistent with the applicable LCD
Whether the wound type and characteristics meet coverage criteria at the time of order
Whether there is documentation of a face-to-face encounter to support the order

For mobile wound care practitioners, NPWT is often a significant part of the clinical and billing picture. The risk area is not the application itself — it is the ordering documentation that goes with the DME supplier's claim. If your note doesn't support the criteria the DME supplier is billing against, both the DME claim and your professional services claim are at risk.

Documentation Gaps That Trigger OIG Attention

Most OIG audit findings in wound care trace back to documentation rather than outright fraud. The practices that get hit hardest are those where the clinical care was appropriate but the record doesn't prove it. Specific documentation gaps that appear repeatedly in OIG reports and that wound care LCD compliance requires:

Missing wound measurements. Size, depth, presence of tunneling or undermining must be recorded at each visit for debridement and graft claims to be defensible.
Absent or incomplete treatment history. Many LCDs require documentation of a minimum conservative treatment period before advanced therapies can be approved. If that history isn't in the chart, the graft or advanced wound therapy claim lacks its foundation.
No documented response to treatment. Progress notes that lack wound-bed assessment findings — granulation, epithelialization, exudate level, infection status — cannot demonstrate that clinical decisions were evidence-based.
Diagnosis-to-procedure mismatch. The ICD-10 code on the claim must map logically to the procedure performed. Coding a fully granulated wound while billing for debridement is a pattern audit algorithms catch quickly.

How Mobile Wound Care Practices Can Reduce OIG Exposure

Mobile wound care practices have specific structural vulnerabilities that hospital-based programs don't share. Without the documentation infrastructure of a facility, the risk of gaps in medical records — particularly around conservative treatment history and visit-to-visit progression — is higher. Practical steps that reduce OIG exposure:

Conduct a quarterly internal coding audit. Pull a sample of ten to fifteen claims across your highest-volume CPT codes and compare the documentation to what was billed. If your notes wouldn't withstand an ADR (Additional Documentation Request), strengthen the template before you get one. See Wound Care Billing Compliance Audit for a structured audit framework.

Use structured wound measurement at every visit. AI-assisted or ruler-based measurement documented at every encounter eliminates one of the most common audit vulnerabilities. Wound area in cm² should appear in every note where debridement or graft services are billed.

Separate the ordering note from the treatment note. When you are ordering NPWT or skin substitutes, that medical necessity documentation should be explicit — not embedded in the treatment note and not assumed from prior visits.

Track your Q-codes against your product inventory. If the HCPCS code on your claim doesn't match what you pulled from inventory and applied, the discrepancy is exactly what OIG document-match audits are designed to detect.

Know your LCD by jurisdiction. Not all MACs apply the same criteria. The documentation that satisfies Palmetto GBA's LCD may not satisfy Novitas or CGS. Your compliance framework needs to reflect your MAC's specific requirements, not a generic national standard.

Key Takeaways

The OIG Work Plan 2026 specifically targets skin substitute claims, debridement upcoding, and NPWT ordering documentation in wound care.
Skin substitute claims draw review for Q-code accuracy, missing wound measurements, and applications performed before conservative treatment is documented.
Debridement upcoding risk centers on excisional codes billed without clinical documentation supporting the required depth and tissue removal.
Documentation gaps — not fraudulent billing — account for the majority of OIG and RAC findings in wound care.
Mobile practices can reduce exposure through quarterly internal audits, structured wound measurement at every visit, and MAC-specific LCD compliance review.
