HCPCS Code A4385: Ostomy Skin Barrier, Solid 4×4 or Equivalent, Extended Wear, Without Built-in Convexity, Each

HCPCS code A4385 describes an "Ostomy skin barrier, solid 4x4 or equivalent, extended wear, without built-in convexity, each." It is used for billing and reimbursement of this specific type of ostomy supply under Medicare and other payers.

Medicare may cover HCPCS code A4385 when the beneficiary has a surgically created stoma and medical necessity is documented. Coverage is subject to utilization limits set in Medicare’s LCDs for ostomy supplies (e.g., maximum number of barriers per month). Adherence to SWO and documentation requirements is required for approval.

Ostomy barrier strips are adhesive, skin-friendly products used to create a secure seal around the stoma. They prevent leakage, protect the skin, fill uneven skin contours, and keep the ostomy pouch firmly in place, enhancing comfort and wear time during daily activities.
