Revenue Codes are four-digit numeric codes used on the UB-04 (CMS-1450) claim form to identify the department or cost center where healthcare services were provided. These codes help insurance companies understand the type of service, the location within the healthcare facility, and the charges associated with institutional claims.
Revenue Codes are primarily used by hospitals, skilled nursing facilities (SNFs), home health agencies, rehabilitation centers, hospice organizations, and other institutional healthcare providers. They work together with Type of Bill (TOB), ICD-10-CM diagnosis codes, CPT®/HCPCS codes, and Place of Service (POS) (when applicable) to ensure accurate claim submission and reimbursement.
Understanding Revenue Codes is essential for professionals working in institutional medical billing, payment posting, claim submission, and Revenue Cycle Management (RCM).
