Which document is commonly used to submit professional claims to payers in the United States?

• A. UB-04 (CMS-1450) claim form
• B. 837-PX electronic claim form
• C. HCFA 1500 form
• D. CMS-1500 (HCFA 1500) form

Answer: (D)

Professional claims billing is commonly done on the CMS-1500 form, which is the current standard paper claim form used by physicians and other professionals to bill payers for services. It collects essential details like patient information, provider identifiers, diagnosis codes, and procedure codes so payers can process reimbursements. The UB-04 is used for institutional or facility claims (such as hospitals), not for professional services. Electronic submissions exist as the 837-PX transaction under HIPAA, but that is an electronic format, not a paper document. The HCFA 1500 refers to the older name for the same form, with CMS-1500 being the updated designation.
