Clinical & Coding Specifications
Clinical Context
A patient presents to an outpatient wound care clinic with a superficial partial-thickness pressure injury on the sacral area after limited mobility. The wound measures approximately 2.5 cm x 3 cm (less than 16 square inches), is clean with minimal exudate, and requires a sterile occlusive dressing to maintain a moist healing environment and protect from contamination. A licensed wound care nurse or physician assesses the wound, performs wound cleansing and debridement as needed, documents size, exudate, and skin around the wound, and applies a sterile hydrocolloid dressing sized under 16 sq. in. The dressing is coded as A6234 for each dressing supplied. Follow-up visits occur in the clinic or home health setting for dressing changes every 3–7 days based on exudate and clinical judgment. Typical payors include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare. Patient instructions and wound care plan are documented in the medical record, including healing goals and next evaluation date.
