What type of billing does the Uniformed Bill (UB 04) primarily address?

The Uniformed Bill (UB 04) is specifically designed for inpatient billing. It serves as a standardized form used by hospitals and other healthcare facilities to submit claims for services provided to patients who are admitted and receive care as inpatients. This form captures detailed information regarding the patient's hospital stay, including diagnoses, procedures performed, the length of stay, and itemized charges. It is essential for ensuring accurate reimbursement from payers for the extensive services provided during an inpatient admission.

While the other options pertain to specific types of healthcare billing, such as outpatient services, emergency care, or pharmaceuticals, they do not align with the primary purpose of the UB 04. The UB 04 focuses solely on inpatient hospital claims, making it a critical tool for healthcare providers managing inpatient care documentation and billing processes.
