What purpose do "C" codes serve in HCPCS coding?

The "C" codes in HCPCS coding are specifically designed for reporting services and procedures related to hospital outpatient services. These codes help healthcare providers and code specialists categorize and bill for various outpatient services rendered in hospitals, ensuring that the services provided are compensated accurately. In the context of outpatient care, these codes capture various aspects of treatment, diagnostic testing, and other services that patients receive in a hospital setting where they are not admitted as inpatients.

The use of "C" codes facilitates appropriate billing and coding for these services, which is essential for reimbursement and data collection in outpatient scenarios. Understanding the purpose of these codes is vital for coding professionals who need to ensure compliance with regulatory standards while optimizing the financial operation of healthcare facilities.
