The UB-04 form, also known as the form CMS-1450, is the uniform institutional provider hard copy claim form for billing multiple third party payers. Form UB-04 is very similar to the CMS-1500, but it is used by institutional healthcare providers like hospitals. The UB-04 is used in place of electronic claims as approved by the ASCA. The UB-04 is standardized and contains all the basic information needed to submit an accurate claim, although not all payers require the same data elements as required by Medicare.
The insurance claims process can be complex and time consuming.
