Medicare Audit Readiness for Wound Care: FAQ for Podiatrists
faq
Answers to the questions podiatrists ask about surviving a wound care audit — from debridement depth to LCD compliance for skin substitutes.
Wound care and podiatry practices field more record requests than almost any specialty. These are the questions that come up most often about staying audit-ready.
What triggers a wound care audit?
High-frequency debridement codes, CTP application volume, and outlier billing patterns for a given NPI. Repeated 11043–11047 claims without documented depth are a common flag.
How is debridement supposed to be coded?
By the deepest level of tissue actually removed — skin, subcutaneous, muscle, or bone. The note must describe the tissue removed at that depth, not the tissue exposed. "Debrided to healthy tissue" is not sufficient.
What does an LCD compliance check for skin substitutes cover?
Ulcer duration (typically ≥4 weeks of documented conservative care), wound etiology, vascular status, offloading, and glycemic control. Missing any one of these is the usual denial reason.
How far back can Medicare claw revenue in a retroactive audit?
Extrapolated findings can reach across years of claims. A single audit can offset a full year of DFU revenue if debridement depth or CTP necessity is not defensible in the chart.
What makes a chart "audit-ready by default"?
Pre-sign compliance checks that run before the note is signed, not after the claim is filed. See Medicare audit readiness for wound care for how pre-sign checks close the gap.
How do the 2026 CMS rules change skin substitute billing?
They tighten coverage and pricing for CTPs. Details are in the breakdown on skin substitutes after the 2026 CMS rule.
Do mobile visits carry different audit risk?
Yes — documentation gaps are more common when charting happens hours after the visit. Real-time capture matters more, not less, for mobile providers.
