How many main categories are in the HCPCS Level II coding system?

The HCPCS Level II coding system consists of two main categories: the alphanumeric codes and the modifiers. This structured approach allows for better organization and categorization of health care procedures and equipment not covered by CPT codes, particularly those related to Medicare and Medicaid services.

The first category includes the alphanumeric codes, which are used to identify products, supplies, and certain services not included in the Current Procedural Terminology (CPT) system. The second category features modifiers that provide additional information about the service provided, indicating aspects such as whether a procedure was altered or if multiple services were performed on the same day.

Understanding that there are two main categories helps in navigating HCPCS Level II codes effectively, ensuring proper coding and billing practices within the healthcare system.
