What is the UB-04 form primarily used for?

• A. To authorize clinical trials enrollment.
• B. To request patient medical records from another facility.
• C. To bill payers for facility services, including inpatient and outpatient care.
• D. To document nursing assessments.

Answer: (C)

The UB-04 form is a standardized billing document that facilities use to request payment from payers for the care they provided. It captures line-item charges for inpatient and outpatient services, including revenue codes, diagnoses, procedures, dates of service, and patient and payer details so the hospital or clinic can seek reimbursement from insurance plans and government programs. This makes it the primary vehicle for billing and claims submission, whether sent on paper (CMS-1450) or electronically.

Other options don’t fit because they describe unrelated processes: authorizing clinical trials enrollment is a research-related activity, not a billing form; requesting patient medical records is a release-of-information task; documenting nursing assessments belongs in the clinical record, not the billing document.
