What Is the UB-04 Form in Medical Billing?
UB-04 Form is a formal claim Form, a facility based claim form that the institutional providers submit to insurance companies, Medicare and Medicaid. Hospitals, skilled nursing facilities, rehabilitation centers and outpatient departments are some of the common users.
The UB-04 Form is specifically utilized in the process of institutional billing as opposed to CMS 1500 form which is utilized by individual physicians and professional providers. It captures revenue codes, type of bill information, value codes, occurrence codes and charge information in detail.
The form has a standardized form as per the regulation set by the Centers of Medicare and Medicaid Services so that all institutions report on the claims in the same way throughout the United States.
When to Use the UB-04 Form
Facility related services need to be billed using UB-04 Form by institutional providers. These typically include:
- Inpatient hospital stays
- Outpatient processes and diagnostics.
- Visits to emergency departments.
- Skilled nursing services
- Home health and hospice services.
Any service to be billed on a facility provider number and not on a single practitioner usually needs to be filed on the UB-04 Form. This is also the model of commercial payers in handling institutional claims.

Institutional claims need ICD diagnosis codes and might, in numerous instances, demand CPT or HCPCS procedure code. The codes should be supportive of medical necessity and must also be in line with the documented services.

The bill type determines the type of facility, bill category and frequency. The choice of the right code will make sure that the payer will process the claim correctly.
