The Healthcare Common Procedure Coding System (HCPCS) is a coding set used mainly for Medicare, Medicaid, and many other payers. Level I of HCPCS is the CPT code set; Level II is a separate group of alphanumeric codes for things CPT does not describe — such as durable medical equipment, drugs, supplies, prosthetics, and certain services.
Level II codes start with a letter followed by four digits. They are how a claim reports items like a wheelchair, an injectable drug, or a supply that a plain procedure code cannot capture.
Why it matters for billing
When a service involves a drug, supply, or piece of equipment, using the correct HCPCS Level II code — with the right units and any required modifiers — is what gets those items reimbursed. Wrong or missing HCPCS coding leaves money uncollected or triggers denials.
