The UB-04 (also called the CMS-1450) is the standard claim form for institutional providers — hospitals, facilities, and similar entities. Its electronic equivalent is the 837I transaction.
It captures facility-specific information such as revenue codes, occurrence and value codes, and other details that a professional claim does not use. Facility billing follows different rules from professional billing, and the UB-04 reflects that.
Why it matters for billing
Using the correct claim type is basic to getting paid: facility charges belong on the UB-04, professional charges on the CMS-1500. Sending the wrong form or mixing facility and professional data leads to rejections and rework.
