A 4-day inpatient stay would be billed on a CMS-1450 claim form, also known as UB-04, as it is used by hospitals and inpatient facilities for their billing.
Step-by-step explanation:
A 4-day inpatient stay would typically be billed on a CMS-1450 claim form, also known as the UB-04 form. This form is utilized by hospitals and inpatient facilities to bill for their services. It's different from the CMS-1500 form, which is used by non-institutional providers and suppliers, such as physicians and outpatient services, to bill Medicare Part B-covered services. The ADA dental form is specifically for dental services and would not be applicable to an inpatient stay.
