Many are familiar with a medical form called the UB-04. It stands for “Universal Bill 2004” and is the name of a billing form used by hospitals and other facility providers. (Physicians typically use the HCFA 1500 form which is somewhat similar.)
What some don’t realize is that Medicare gives the UB-04 its own designation as CMS Form-1450. Few call it that because it serves many different providers and payers than just CMS.
In practical terms both HCFA-1500 and UB-04 paper forms have been superseded as health care has moved away from pieces of paper. Today, claims are submitted electronically for paper using an electronic data interchange standard, ASC X12 837. There are multiple flavors of this standard, but the 837p standard is typically used for professional (physician) claims while the 837i standard is used for institutional (hospital) claims
