Hospital outpatient services are reported on the __________.

Hospital outpatient services are reported on the CMS-1450 Form, also known as the UB-04. This form is specifically designed for billing hospitals and other facilities for services provided to patients in an outpatient setting.

The CMS-1450 Form includes fields that accommodate various types of care rendered, including services for outpatient surgeries, emergency room visits, and diagnostic tests. It captures relevant details about the patient, the services received, and the financial aspects of the services, which are essential for the reimbursement process.

In contrast, the other forms mentioned serve different purposes: the CMS-1500 Form is typically used for billing individual practitioners and providers in professional settings, the CMS-1400 Form is not a standard billing document recognized in this context, and the CMS-1300 Form does not exist in the context of healthcare billing. Thus, the use of the CMS-1450 is specific to hospital outpatient services and is crucial for accurate reporting and reimbursement.
