Which type of services are typically classified under HCPCS rather than CPT?

Services classified under HCPCS (Healthcare Common Procedure Coding System) primarily include items and services that are not typically covered by CPT (Current Procedural Terminology). Transportation services, specifically, fall into the category of services that HCPCS is designed to code. This includes ambulance services and non-emergency medical transportation, which are vital for patients who may require transport to and from medical facilities but do not involve procedures or visits that are encompassed by the CPT codes.

In contrast, emergency room visits, surgical procedures, and wellness exams are all clinical activities that involve specific patient interactions and treatments, which are well-captured by the CPT coding system. These are more focused on procedural and diagnostic aspects of healthcare rather than services that are more logistical in nature, like transportation. Thus, transportation services stand out as the primary candidates for HCPCS classification, aligning with the system's purpose to encompass a broader range of healthcare services.
