HCPCS code
Updated September 30, 2026
Definition
A code from the Healthcare Common Procedure Coding System. Bills and claims use these codes to name services, supplies, drugs, and equipment.
The Healthcare Common Procedure Coding System (HCPCS) is a standard set of codes for health care. It helps Medicare and other health plans process claims the same way every time.
It has 2 levels. Level I codes are CPT codes, which are 5 numbers. They mostly cover services from doctors and other clinicians. Level II codes are 1 letter followed by 4 numbers. They cover things CPT codes don't, like ambulance rides, some drugs, and medical equipment and supplies.
You'll see these codes on an itemized bill and on your explanation of benefits (EOB). Each code should match care you actually got. A wrong code can change the price or cause a denial. If a code looks off, ask the billing office what it means. Our guide on how to get an itemized bill shows how to get a bill with every code listed.
