Segment

Authorization information

Carries pre-authorization and certification details from a payer, including the authorizing payor or plan, authorization number, authorized number of treatments, reimbursement limit, and authorization effective and expiration dates. It is used in REF referral messages and BAR transactions when insurance pre-authorization is required for a procedure. Referring provider systems send AUT data obtained from payer interactions to the referred-to provider.

FAQ

Frequently asked questions

AUT contains authorization information including authorization numbers, dates, authorized services, and payer details. It tracks authorizations for wellness programs and preventive care visits.

Use authorizing_payor_plan_id and authorizing_payor_company_id fields:

aut.authorizing_payor_plan_id = CWE(
    identifier='WELLNESS01',
    text='Wellness Benefits Plan'
)
aut.authorizing_payor_company_id = CWE(
    identifier='HLTH001',
    text='HealthFirst Insurance'
)

Use authorized_number_of_treatments to specify how many visits or sessions are covered by the authorization for wellness programs.

RF1 contains referral information while AUT contains authorization details. Both segments work together to manage referrals and their associated insurance authorizations for wellness services.

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.
