Which claim form is mainly submitted by institutions?

The UB-04 claim form is specifically designed for institutional providers to submit claims for services rendered. This form is used primarily by hospitals, nursing facilities, and other institutional healthcare providers when billing for inpatient and outpatient services. The UB-04 is standardized and allows for comprehensive reporting of hospital services, including room and board, surgery, and other related services.

The other forms listed do not serve the same purpose for institutions. The HCFA-1500, for example, is used by individual healthcare providers, such as physicians or specialists, primarily for outpatient services. The CMS-1450 is effectively another name for the UB-04 and is not commonly referenced in current practice as a standalone form. The UB-92, though previously used before the UB-04 was adopted, is now outdated and no longer the standard.

Thus, the UB-04 is the correct form as it is specifically tailored for institutional billing, making it the primary claim form submitted by these types of healthcare facilities.
