The Uniform Billing Code of 1992 (UB-92) refers to a standardized institutional billing form/format used by hospitals and other institutional providers to submit claims to health insurers. In a claims workflow, standardization matters because the insurer needs consistent data to apply coverage rules, pricing, coordination of benefits, and claim-edit logic.
UB-92 is often discussed as a predecessor to later standardized institutional billing formats (such as UB-04). The exact format and required fields can vary by payer and era, but the core idea is consistent: institutional claims must be itemized and coded in a standard way to be processed efficiently.
What information the UB-92 format carries
Institutional billing formats typically include fields such as:
- patient and subscriber identifiers
- provider and facility identifiers
- dates of service and bill type
- diagnosis information and service codes used for adjudication
- revenue codes / service line items, charges, and units
- attending/referring provider information where required
How insurers use it in claim adjudication
Health insurers use standardized claim formats to:
- verify eligibility and coverage at the date of service
- apply benefit rules (deductible, copay, coinsurance, limits)
- detect inconsistencies (for example, impossible date combinations)
- coordinate benefits when more than one plan may apply
- generate an explanation of benefits (EOB) showing what was allowed, paid, and owed
Common sources of denials and delays
Institutional claims can be denied or pended when required fields are missing, coding is inconsistent, documentation is insufficient, or coordination-of-benefits information is incomplete. Many insurers treat these issues as “claim cleaning” and will request corrections rather than making a final denial.
