What is the purpose of the Healthcare Common Procedure Coding System (HCPCS)?

The Healthcare Common Procedure Coding System (HCPCS) serves a specific function in the healthcare industry that distinguishes it from other coding systems. HCPCS is utilized primarily to provide codes for various services and procedures that are not included in the Current Procedural Terminology (CPT), particularly focusing on items such as medical supplies, equipment, and certain non-physician services. This coding system includes two levels: Level I, which consists of CPT codes, and Level II, which covers a wide range of non-physician services including ambulance services, durable medical equipment, and various drugs and supplies.

By having a distinct coding system for these additional services and items, HCPCS ensures that healthcare providers and payers can communicate effectively about services rendered that fall outside the scope of CPT codes. This is crucial for accurate billing and reimbursement processes within the healthcare system.

The other options do not align with the primary purpose of HCPCS, as it does not focus on medical diagnoses or insurance policies and does not involve tracking patient vital signs. Therefore, the distinction and comprehensive coverage provided by the HCPCS in coding non-CPT services and supplies make this option the most accurate choice.
