Summary & Overview
CPT 97597: Selective Debridement of Devitalized Tissue, Wound ≤20 cm2
CPT code 97597 represents selective debridement of devitalized tissue from an open wound with treated surface area of 20 cm² or less. This code is used to capture clinician-performed removal of necrotic tissue using a range of techniques and may include topical agents, wound assessment, whirlpool therapy, and patient instructions. Accurate coding for debridement is important nationally because wound care is common, resource‑intensive, and a focus of quality and utilization oversight.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find national benchmarks for how this service is classified relative to related wound care codes, clarification on clinical context for appropriate use, and a summary of common billing relationships with adjacent codes used for larger wound areas or different debridement methods. The publication also outlines sites of service where 97597 is typically billed and contrasts it with closely related codes used for additional wound surface area or non‑selective techniques.
This summary is intended for clinicians, practice managers, coding professionals, and policy stakeholders seeking a concise reference on the clinical scope and payer landscape for selective debridement of small wound areas. Data not available in the input: specific utilization rates, payer-specific coverage rules, and reimbursement amounts.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with peripheral vascular disease and type 2 diabetes presents to an outpatient wound clinic for evaluation of a chronic non‑healing lower‑leg ulcer. The wound measures 18 cm² after cleansing, with devitalized (necrotic) tissue and slough at the base and bedside signs of local inflammation but no systemic sepsis. The clinician (a nurse practitioner or physician assistant) performs selective sharp debridement: removal of devitalized tissue from the open wound bed using forceps and scissors, irrigates the wound, applies topical antimicrobial dressing, documents wound dimensions and appearance, provides patient and caregiver instructions for ongoing dressing changes, and schedules follow‑up. Billing is reported with 97597 for the first 20 cm² of wound surface area treated. Typical documentation includes wound size, depth, tissue types removed, presence/absence of infection, pain management used, total time, and instructions provided. Typical sites of service include outpatient wound centers, physician office clinics, home health visits, and skilled nursing facilities when appropriate.
