What is an example of a service not reflected in CPT codes but noted in HCPCS?

Transportation services are often captured in HCPCS (Healthcare Common Procedure Coding System) codes rather than in CPT (Current Procedural Terminology) codes. HCPCS includes codes for services that might be outside the scope of what is typically included in the CPT system, which primarily focuses on medical, surgical, and diagnostic procedures.

For example, ambulance services and other types of patient transportation that do not involve a medical procedure fall under HCPCS. These transportation services are necessary for patient care but are not categorized in the same way as imaging studies, diagnostic tests, or routine office visits, which all have corresponding CPT codes. While the CPT coding system is extensive for clinical procedures and diagnostic services, it does not encompass non-clinical services like transportation, thus making HCPCS the appropriate coding system for such services.
