Why wound care billing is uniquely complex

Wound care is one of the most documentation-intensive billing specialties. Wound care billing codes span multiple CPT categories, require precise wound measurement documentation, and must match the exact debridement method used. For NC providers relying on Wound Care Billing Services in North Carolina, getting this right directly impacts reimbursement.

Key CPT codes for wound care

Debridement codes (CPT 97597–97598): Active wound care management using selective debridement. 97597 covers the first 20 sq cm; 97598 covers each additional 20 sq cm. These are high-value codes that require documentation of wound bed, size, and tissue type.

Non-selective debridement (CPT 97602): Used when wet-to-dry or enzymatic debridement is performed. Lower reimbursement but commonly used in nursing facility settings.

Surgical debridement (CPT 11042–11047): For subcutaneous tissue and deeper. These wound care CPT codes require physician involvement and higher documentation standards.

Negative pressure wound therapy (NPWT — E2402): For DME suppliers billing NPWT devices. Requires a physician order and documentation of wound response.

ICD-10 codes for wound care

Common ICD-10 codes include L89 series (pressure ulcers), L97 (non-pressure chronic ulcers of lower limb), and E11.621 (Type 2 diabetes with foot ulcer). Always code the underlying condition alongside the wound code — payers require both for medical necessity.

Documentation requirements

Every wound care billing visit needs: wound location, dimensions (length x width x depth in cm), wound stage or classification, tissue type, treatment rendered, and the provider’s response assessment. Missing any element is the fastest route to a denial.
