Fill Out Form UB-04 Online in 2026

The CMS-1450, or UB-04 form, is a standardized medical claim form used by healthcare facilities such as hospitals and nursing homes. This form allows providers to submit essential billing details to insurance companies, including Medicare and Medicaid, for reimbursement. By including comprehensive information about the services rendered and the associated charges, the CMS-1450 ensures accurate and prompt payment. Filling it out correctly is vital for healthcare providers to prevent reimbursement delays and potential audits.

Form UB-04 is essential for healthcare billing. Here’s what it’s used for:

• Billing Reimbursement: Submitting claims for care received by patients to insurance providers, including Medicare and Medicaid.
• Detailed Information: Offering detailed descriptions of services provided and associated charges.
• Comprehensive Record: Keeping a complete record of all reimbursable care, including necessary revenue codes for the payer.

1. Identify the Claim Type: Choose between inpatient or outpatient claim.

2. Complete Claim Details: Fill in Blocks 1-5 with provider info, patient details, and claim type.

3. List Diagnoses and Procedures: Match diagnoses in Blocks 67A-Q with procedures in Blocks 74 and 74a-e.

4. Itemize Services and Supplies: Enter each service and supply in the designated sections.

5. Include Revenue Codes and HCPCS Codes: Add these codes for outpatient claims.

6. Ensure Accuracy and Completeness: Double-check all fields for accuracy and completeness.

Institutional providers, including hospitals and nursing facilities, are responsible for completing Form CMS-1450.

After completion, the form is used by these providers to bill Medicare fiscal intermediaries and Medicaid State Agencies for services rendered.

Form UB-04 is not necessary for providers with fewer than 25 full-time equivalent employees billing a Medicare Administrative Contractor. It’s also not required for roster billing, Medicare demonstration projects, or when multiple primary payers are involved in MSP claims. Providers who do not address exception requests may face claim denials.

There is no single, universal due date for submitting the UB-04 form. The form must be submitted after services are rendered and within the timely filing period specified by each payer. For Medicare, this means submitting the claim after the date of service (outpatient) or discharge (inpatient), but always before the payer’s timely filing deadline. For authoritative details, always consult the official NUBC and AHA resources or your specific payer’s billing guidelines.
