What Is CPT 97597?
CPT 97597 reports selective debridement of the first 20 square centimeters of wound surface area. Selective debridement means removing devitalized tissue -- slough, fibrin, loose eschar, biofilm -- from the wound bed without cutting through to viable, bleeding tissue underneath. The tissue being removed is already dead. The clinician is clearing it so that the wound bed can granulate and heal.
This is the debridement code billed at the majority of wound care visits. Most routine wound maintenance involves surface-level removal of nonviable material, not aggressive excision into viable tissue planes. When the wound bed after debridement looks the same as before -- granulation tissue that was already present, now visible because the slough on top has been removed -- that is 97597.
What instruments qualify for selective debridement?
The instrument does not determine the code. The tissue depth reached determines the code. A clinician may use a curette, scissors, forceps, or even a scalpel for selective debridement. What makes it selective is that the debridement stayed within the layer of nonviable tissue and did not extend into viable underlying structures.
This is a common source of confusion. Some billers default to excisional codes (11042) whenever a scalpel is used. That is incorrect. A scalpel used to shave off adherent eschar without reaching bleeding subcutaneous tissue is still selective debridement. The question is not what tool was in the clinician's hand -- it is whether the clinician cut to viable tissue.
What documentation is required for 97597?
A defensible 97597 claim requires the following elements in the clinical note:
Pre-debridement wound assessment. Wound dimensions (length, width, depth), tissue types present in the wound bed (percentage of slough, eschar, granulation, epithelial tissue), and the clinical indication for debridement. The note must establish that devitalized tissue was present and needed to be removed.
Method and instrument. What the clinician used -- curette, scissors, wet-to-dry, forceps -- and the technique applied. This supports the selective classification when it describes surface-level removal rather than deep excision.
Tissue type removed. Name the specific tissue: "removed adherent fibrinous slough from wound surface" or "debrided loose necrotic eschar from wound margins." Vague language like "debridement performed" does not support any code on audit.
Post-debridement wound description. The wound bed appearance after debridement. For selective debridement, the note should describe existing granulation tissue now visible, not newly exposed bleeding tissue. The absence of a bleeding-tissue description is what distinguishes this from excisional debridement documentation.
Total wound surface area debrided. Measured in square centimeters. 97597 covers the first 20 sq cm. If >20 sq cm was debrided, the add-on code 97598 captures each additional 20 sq cm increment.
What does Medicare reimburse for 97597?
The 2026 Medicare Physician Fee Schedule national average for 97597 is approximately $80-$90 in the non-facility (office) setting. Actual reimbursement varies by geographic locality adjustment (GPCI), place of service, and provider type (physician vs. NP/PA with incident-to considerations).
The add-on code 97598 reimburses approximately $40-$55 per additional 20 sq cm unit. For a 45 sq cm selective debridement, the claim would include 97597 x1 plus 97598 x1.

When is 97597 the wrong code?
97597 is incorrect when the clinical record describes excisional debridement -- cutting through devitalized tissue until viable, bleeding tissue is reached. If the note documents active bleeding at the wound base or margins, describes excision to the level of subcutaneous fat, muscle, or bone, or records a tissue plane change from debridement, the correct code is 11042-11047, not 97597.
The most common error is the reverse: performing excisional debridement but documenting it as selective because the clinician did not describe the tissue depth reached. This results in undercoding that costs $40-$60 per visit -- real revenue left on the table because the note was incomplete.
