The Healthcare Common Procedure Coding System (HCPCS, pronounced “hix-pix”) maintained by the Centers for Medicare & Medicaid Services comprises two medical code sets, HCPCS Level I and HCPCS Level II.

Level I consists of the Current Procedural Terminology© (CPT), a classification index which, as Applied Policy has previously discussed, is developed, maintained, and copyrighted by the American Medical Association. 

With nearly 11,000 codes, CPT is extensive. But it is far from comprehensive and is not intended to be. As its unabbreviated name states, CPT’s focus is the medical procedures provided and performed by physicians and other healthcare professionals. It was not developed to allow for the classification of thousands of medical products and services, especially those used or delivered outside of an office setting. 

HCPCS Level II fills this classification gap by providing a coding system for such items as durable medical equipment, prosthetics, orthotics, and supplies used outside of a physician’s office; drugs and biologicals not classified by CPT; ambulance services; and even certain episodes of chaplain spiritual care.
