Debridement depth determines the code
Selective debridement and surgical debridement of skin, subcutaneous tissue, muscle or bone are entirely different codes. Notes that describe debridement without specifying the deepest tissue removed cannot be billed correctly.
Surface area and add-on units
Debridement codes are billed by area with add-on units beyond the first block. Missing measurements systematically underpay every wound visit.
Skin substitute coverage and product codes
Skin substitute application is governed by coverage policy on wound type, duration, conservative care and number of applications, and each product bills under its own code with wastage rules.
Hyperbaric oxygen therapy
HBO is covered only for specific indications, with documentation of the qualifying condition and prior failed therapy. Non-covered indications are denied outright.
Serial visits and medical necessity
Wound care is repetitive by nature. Payers expect documented progress or a documented change in plan; static notes across months invite denials and audits.
