What form is used for filing paper claims in an inpatient setting?

The UB-04 form is specifically designed for filing paper claims in an inpatient setting. This form is utilized by healthcare facilities, such as hospitals, to submit their claims for services provided to patients who are admitted for care. It captures important information such as the types of services rendered, the diagnosis codes, and the total charges for the patient’s stay.

In an inpatient setting, the UB-04 is the standard format required for billing and is recognized by Medicare and other insurers for processing these types of claims. It differs from other forms like the CMS-1500, which is primarily used for outpatient services and physician claims. The 837P is an electronic claim format used for outpatient services, while the CMS-1550 is not a standard claim form in this context. Therefore, the UB-04 is the correct and appropriate choice for filing inpatient claims.
