On August 17, 2000, 45 CFR 162.1002 established the HCPCS level II codes as part of the regulation to implement the Health Insurance Portability and Accountability Act (HIPAA) requirement for standardized coding systems.

• The HCPCS Level II codes were established so providers and suppliers can submit claims for services, supplies, and equipment that aren’t identified by the HCPCS Level I Current Procedural Terminology (CPT®) codes. 
• CMS maintains HCPCS Level II codes, including decisions about additions, revisions, and deletions to the codes.
