The Healthcare Common Procedure Coding System (HCPCS) is a collection of codes that represent procedures, supplies, products and services which may be provided to Medicare beneficiaries and to individuals enrolled in private health insurance programs. The codes are divided into two levels, or groups, as described below:
Codes and descriptors copyrighted by the American Medical Association’s current procedural terminology, fourth edition (CPT-4). These are 5 position numeric codes representing physician and nonphysician services.
CPT-4 codes including both long and short descriptions shall be used in accordance with the CMS/AMA agreement. Any other use violates the AMA copyright.
Includes codes and descriptors copyrighted by the American Dental Association’s current dental terminology, (CDT-2022). These are 5 position alpha-numeric codes comprising the d series. All level II codes and descriptors are approved and maintained jointly by the alpha-numeric editorial panel (consisting of CMS, the Health Insurance Association of America, and the Blue Cross and Blue Shield Association). These are 5 position alpha- numeric codes representing primarily items and nonphysician services that are not represented in the level I codes.
