HCPCS A-codes — Medical & surgical supplies, ambulance
A-codes cover medical and surgical supplies billed to the DME MACs — diabetic testing supplies, CPAP interfaces, ostomy, wound care, and incontinence products. Most are inexpensive but high-volume, so quantity limits and resupply cadences drive denials.
852 active codes in the April 2026 HCPCS file. PA = on Medicare's required prior-authorization list · Fee schedule = April 2026 DMEPOS amounts published.
