HCPCS Level II code A6235 denotes a sterile hydrocolloid wound dressing measuring greater than 16 square inches and up to 48 square inches, supplied without an adhesive border and billed per dressing. These dressings are commonly used in wound care to provide a moisture-retentive environment that supports autolytic debridement and protects wounds from contamination. Nationally, accurate coding of durable medical supplies like A6235 affects claims processing, coverage determinations, and cost management for post-acute and outpatient wound care.
Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a partial-thickness or full-thickness wound (for example, a pressure ulcer stage II–III, surgical dehiscence with significant exudate, or a traumatic skin abrasion) requiring a sterile hydrocolloid wound cover larger than 16 square inches and up to 48 square inches. The dressing A6235 is applied in an outpatient wound care clinic, home health visit, long-term care facility, or emergency department triage area by a licensed nurse or wound care clinician after wound assessment and cleaning.
A typical clinical workflow: a clinician documents wound size, depth, and exudate level; performs cleansing and debridement if indicated; measures the wound and confirms that a hydrocolloid pad >16 sq. in. and ≤48 sq. in. without adhesive border is appropriate; selects and applies the sterile dressing per manufacturer instructions; records dressing lot number and size in the medical record; and instructs the patient or caregiver on wear time, signs of infection, and follow-up. Billing uses HCPCS Level II code A6235 for each dressing provided, with modifier(s) appended as appropriate for circumstance, provider status, or payer requirements.
