Clinician Utilization Metadata
HCPCS Procedural Code	Healthcare Common Procedure Coding System (HCPCS) procedural code billed by the individual clinician
HCPCS Code Description	Description of the HCPCS code for the specific medical service furnished by the individual clinician. HCPCS descriptions associated with CPT codes are consumer friendly descriptions provided by the AMA. CPT Consumer Friendly Descriptors are lay synonyms for CPT descriptors that are intended to help healthcare consumers who are not medical professionals understand clinical procedures on bills and patient portals. CPT Consumer Friendly Descriptors should not be used for clinical coding or documentation. All other descriptions are CMS Level II descriptions provided in long form. Due to variable length restrictions, the CMS Level II descriptions have been truncated to 256 bytes. As a result, the same HCPCS description can be associated with more than one HCPCS code. For complete CMS Level II descriptions, visit https://www.cms.gov/Medicare/Coding/HCPCSReleaseCodeSets/ Alpha-Numeric-HCPCS.html.
Beneficiary Count	The number of eligible beneficiaries that received the service or procedure identified by the individual clinician's HCPCS code
Service Count	Frequency of individual clinician's performance of the associated HCPCS code within the specified calendar year
