Debridement techniques are performed to remove all tissue necessary to establish a viable margin, thus promoting healing. In addition to necrotic tissue, tissue necessary to establish a viable margin includes senescent cells, rolled skin edges, undermined edges, and abnormal granulation tissue.

Surgical debridement occurs only if material has been excised and is typically reported for the treatment of a wound to clear and maintain the site free of devitalized tissue including necrosis, eschar, slough, infected tissue, abnormal granulation tissue etc., to the margins of viable tissue.

Surgical excision includes going slightly beyond the point of visible necrotic tissue until viable bleeding tissue is encountered in some cases. The use of a sharp instrument does not necessarily substantiate the performance of surgical excisional debridement. Unless the medical record shows that a surgical excisional debridement has been performed, debridements should be coded with either selective or non-selective codes (97022, 97036, 97597, 97598, or 97602).
