Question: I used to bill for a facility and am new to the role of practice manager on the physician side. Can you explain to me when a practice would use the CMS-1500 form instead of the UB-04?

Answer: As a physician practice, you shouldn’t need to use the UB-04 form and you would only use the CMS 1500 form for professional fee services.

However, you may need to use both forms, depending upon payer requirements. Hospital-based ASCs generally use the UB-04 form for facility charges and the CMS-1500 form for the professional charges of the physician, but again check payer guidance.
The definitions of the UB-04 and CMS-1500 are as follows:
