Summary & Overview
HCPCS A6238: Hydrocolloid Wound Dressing, 16–48 sq. in.
HCPCS Level II code A6238 designates a sterile hydrocolloid wound dressing with a pad area greater than 16 square inches and up to 48 square inches, with any size adhesive border, billed per dressing. This supply-level code is commonly used in wound care management for pressure ulcers, diabetic foot wounds, surgical sites, and other wounds that benefit from a moisture-retentive environment. Nationally, codes for advanced dressings like A6238 matter because they drive coverage decisions, influence outpatient supply reimbursement, and affect clinical workflows for wound management across multiple care settings.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn how A6238 is classified and used across typical sites of service, what common clinical contexts prompt its use, and which payers are relevant for coverage considerations. The publication summarizes available benchmarks and policy-relevant points, explains clinical context for wound dressing selection, and identifies where input data was not available. Data not available in the input: associated taxonomies, ICD-10 diagnoses, related codes, and service line details.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a partial-thickness to full-thickness wound requiring a moisture-retentive dressing to promote autolytic debridement and healing. Example: a 68-year-old patient with a diabetic foot ulcer on the plantar surface measuring 30 square inches after debridement in a wound care clinic. The wound care nurse or physician applies a sterile hydrocolloid dressing sized within the code range (greater than 16 sq in and ≤48 sq in) to the cleaned wound bed, secures the dressing with appropriate adhesive border, and provides return-to-clinic instructions. The clinical workflow includes wound assessment (size, depth, exudate), cleansing, selective sharp debridement if indicated, application of topical agents when appropriate, placement of the A6238 hydrocolloid dressing, documentation of wound measurements and dressing lot number, and scheduling follow-up for dressing change and reassessment in 3–7 days depending on exudate and infection risk.
