What type of codes are primarily represented in HCPCS Level II?

HCPCS Level II codes primarily represent codes for medical supplies, equipment, and certain procedures that are not included in the CPT coding system. These codes are essential for billing and documentation of services and items such as wheelchairs, crutches, and other durable medical equipment, as well as certain non-physician services like ambulance services and prosthetics.

While procedure codes are significant and can be found in CPT codes, they are not the primary focus of HCPCS Level II. Diagnosis codes, on the other hand, are categorized under the ICD system. Hence, the emphasis of HCPCS Level II is specifically on medical equipment and supplies, making it crucial for healthcare providers to understand what items and services fall under this coding system for accurate billing and compliance.
