EHC^E20 - Submit Authorization Request (event E20)

If the Authorization is approved, then the Payer Application will return either an Authorization Number (Authorization Identifier on AUT) or individual who has authorized the Authorization Request (Name of Authorizer on AUT). The Authorization Number is not the same number as the Authorization Request Number; the latter indicates the number used to identify the request for authorization. The presence of the AUT segment in the EHC^E24 - Authorization Request Response message implies authorization. However, the Authorization may be restricted, which is described as Payer Adjustments.
