Segment

UB82 billing data

Was designed to carry data elements required for UB-82 (Uniform Bill 1982) institutional claims in the United States, including condition codes, value codes, and occurrence codes. Deprecated as of v2.3 and withdrawn in v2.6, legacy billing system interfaces may still encounter this segment, but modern implementations use UB2 or other billing segments instead.

FAQ

Frequently asked questions

UB1 carries UB82 billing information for healthcare claims, including diagnosis codes, procedure codes, revenue codes, and value codes used for insurance reimbursement.

Use Z00 series ICD-10CM codes for preventive encounters and HCPCS G0422 for initial preventive care examinations. Revenue code 450 indicates preventive care services.

UB1 supports ICD-9CM, ICD-10CM for diagnoses, HCPCS for procedures, and UB92 for revenue and value codes. Each code should include the appropriate coding system identifier.

Use YYYYMMDD-YYYYMMDD format for date ranges, or YYYYMMDD for single dates.

ub1.statement_covered_period = '20240101-20240331'
# or
ub1.statement_covered_period = '20240215'

Code 71 represents institutional claims for facilities other than hospitals, such as wellness centers, rehabilitation facilities, and outpatient clinics.

Zato connects to any system that speaks HL7v2 over MLLP or FHIR over REST. This includes Epic, Cerner, Meditech, Allscripts, and other EHR platforms.

Yes, Zato has built-in MLLP support for sending and receiving HL7v2 messages. MLLP channels handle the framing protocol automatically.

Zato supports HL7 v2.9, which is backward compatible with earlier versions including v2.3, v2.5, and v2.7. Standard segments and datatypes are available as typed Python classes.

Yes. Zato handles both HL7v2 and FHIR natively, so you can parse v2 messages and build FHIR resources with IG-specific extensions in the same service. Typed Python classes are available for both protocols, including extensions from US Core, UK Core, Da Vinci, and other Implementation Guides.
