Clinical Classifications Software for Services and Procedures

The Clinical Classifications Software for Services and Procedures (CCS-Services and Procedures) is one in a family of databases and software tools developed as part of the Healthcare Cost and Utilization Project (HCUP), a Federal-State-Industry partnership sponsored by the Agency for Healthcare Research and Quality. HCUP databases, tools, and software inform decision making at the national, State, and community levels.

The CCS-Services and Procedures provides a method for classifying Healthcare Common Procedure Coding System (HCPCS) codes into clinically meaningful categories. HCPCS is comprised of two levels.

  • HCPCS Level I, commonly referred to as Current Procedural Terminology (CPT®) codes, represent approximately 80 percent of the HCPCS codes and are copyrighted and published by the American Medical Association (AMA). The services and procedures include but are not limited to evaluation and management services, diagnostic and therapeutic surgical and nonsurgical procedures, radiological procedures, laboratory tests, and rehabilitative procedures. CPT codes are updated on a calendar year basis with an extensive update effective on January 1 and a limited "early release" of codes effective on July 1.


  • HCPCS Level II codes are developed and maintained by Centers for Medicare & Medicaid Services (CMS) to describe and identify products, supplies, and services not found in the HCPCS/CPT code set (with the exception of codes for dental services, which are maintained by the American Dental Association). HCPCS Level II codes include but are not limited to descriptions for ambulance services, dental service drugs, infusion additives, devices, durable medical equipment, prosthetics, orthotics, ancillary surgical supplies, nonphysician services, and health care supplies. HCPCS Level II codes are updated quarterly in January, April, July, and October.
The CCS-Services and Procedures provides a method for classifying CPT and HCPCS Level II codes into clinically meaningful procedure categories. The procedure categories are similar to the Clinical Classifications Software for ICD-9-CM procedure classification with the addition of specific categories unique to the professional service and supply codes in CPT and HCPCS Level II codes. The CCS-Services and Procedures is updated annually to coincide with January updates to the HCPCS coding system.
