In which year did CMS incorporate CPT codes as Level I codes into HCPCS?

The incorporation of CPT codes as Level I codes into the Healthcare Common Procedure Coding System (HCPCS) by the Centers for Medicare & Medicaid Services (CMS) took place in 1983. This marked a significant development in the standardization of procedural coding, enabling healthcare providers to consistently report and bill for medical services and procedures. The decision to adopt CPT codes facilitated a unified coding system that improved the efficiency and accuracy of healthcare billing and reporting, ultimately benefiting both providers and patients. This integration into HCPCS allowed for better alignment of reimbursement processes and enhanced tracking of healthcare services.
