Certified Coding Associate (CCA) Practice Exam

The HCPCS coding system, which stands for Healthcare Common Procedure Coding System, is primarily focused on describing healthcare procedures, services, and supplies for billing and reimbursement purposes. It is divided into two levels: Level I consists of CPT (Current Procedural Terminology) codes, which are widely used for reporting medical, surgical, and diagnostic procedures, while Level II codes focus on non-physician services, such as ambulance services, durable medical equipment, and other items not covered by CPT.

By understanding that HCPCS is tailored to various healthcare procedures and related services, one can see how option C accurately reflects its role in the healthcare coding system. This system is crucial for ensuring proper billing practices and facilitating communication between healthcare providers and insurance companies, addressing a wide range of services and supplies necessary for patient care.

In contrast, the other options do not accurately describe HCPCS' purpose or scope. A diagnosis coding system and a patient classification system focus on categorizing patient conditions or classifications, while a procedure coding system can be too broad and does not encapsulate the specific framework and structure that HCPCS provides.
