What Is HCPCS?
HCPCS (Healthcare Common Procedure Coding System) is a standardized coding system maintained by CMS. It has two levels:
- Level I: CPT codes (American Medical Association) — physician services and procedures
- Level II: Alphanumeric codes (A0000–V9999) — ambulance, durable medical equipment, drugs, and supplies not covered in CPT
Common HCPCS Level II Categories
- A codes: Transportation, medical/surgical supplies
- E codes: Durable medical equipment (wheelchairs, crutches, oxygen)
- J codes: Drugs administered other than by oral method
- L codes: Orthotic and prosthetic procedures
Medicare and Medicaid require HCPCS Level II codes for many services that CPT does not cover. Knowing when to use HCPCS vs. CPT is a key billing skill.
