Key Components of Wound Care Billing

Removing non-viable tissue is essential for wound healing. Proper CPT coding ensures correct reimbursement:

2. Skin Substitute Grafts Billing in 2025
Billing for skin substitute grafts now requires enhanced documentation and correct CPT code selection:
| Procedure | CPT Code | Description |
| Small Grafts (<100 cm²) | 15271-15274 | Arms, legs, trunk |
| Large Grafts (>100 cm²) | 15275-15278 | Extensive wound coverage |
CMS 2025 Update: Wastage documentation is now mandatory for graft billing claims.
3. Negative Pressure Wound Therapy (NPWT)
NPWT is reimbursed only with supporting medical necessity documentation.
- CPT 97605 (Wound ≤50 cm²)
- CPT 97606 (Wound >50 cm²)
4. Hyperbaric Oxygen Therapy (HBOT) Billing
- CPT 99183 – Requires pre-authorization and proof of treatment efficacy.
