Like Current Procedural Terminology (CPT®), the Healthcare Common Procedure Coding System (HCPCS) is a code set for billing services and procedures. Unlike CPT, HCPCS is also used to bill supplies, products, durable medical equipment (DME), prosthetics, orthotics, outpatient hospital care, ambulance rides, and certain drugs and medicines provided to Medicare patients and private health insurance program beneficiaries. In general, users deploy HCPCS for services, procedures, and equipment not covered by CPT codes.
