Form CMS-1450 (UB-04)
This form, also known as the UB-04, is a uniform institutional provider bill suitable for use in billing multiple third party payers. Because it serves many payers, a particular payer may not need some data elements. The National Uniform Billing Committee (NUBC) maintains lists of approved coding for the form. All items on Form CMS-1450 are described. The FI must be able to capture all NUBC-approved input data described in section 75 (of the Medicare Claims Processing Manual Chapter 25) for audit trail purposes and be able to pass all data to other payers with whom it has a coordination of benefits agreement.
CMS1450/UB04 Fields: 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, and 28 are places for Condition Codes. The provider enters the corresponding code (in numerical order) to describe any conditions or events that apply to the billing period.
