Specialty
Wound Care Medical Billing
Debridement depth, surface area, and grafts measured in square centimetres.
What makes wound care billing different
Wound care coding turns on two measurements: the depth of tissue removed and the surface area treated. Debridement codes are selected by the deepest tissue level actually removed — not the deepest tissue visible in the wound — and that distinction is where most audit findings land.
Surface area drives everything else. Codes carry a base area with add-ons for each additional increment, so a wound measured casually is a wound coded wrongly, in one direction or the other, on every visit for months.
Debridement depth documented imprecisely
The code follows the deepest tissue removed. A note describing what was seen rather than what was excised cannot support the higher code.
Surface area not measured each visit
Wounds change size. Codes are area-banded with add-ons, so last month's measurement produces this month's error.
Skin substitute units and wastage
Grafts are billed per square centimetre with wastage separately reportable. Both are routinely miscounted.
Selective versus surgical debridement
97597 and the 11042 series are different families with different documentation requirements. Substituting one for the other is a common finding.
Ask any billing company this
“How do you handle skin substitute units and wastage?”
A company that bills your specialty properly will answer this in one sentence. A company that treats every specialty the same will answer it with a brochure.A note on accuracy. Coding rules, coverage policies and payer edits change continually, and the specifics above reflect general practice rather than any individual payer contract or local coverage determination. Treat this page as a map of where to look, not as coding advice for a particular claim.
