The specifications in a service authorization (SA) may change after the delivery of services. If services are delivered by the same vendor and there is a revision to services, such as a change in Maximum Affordable Payment Schedule codes, and manager or medical director approval was required on the initial SA, manager or medical director approval is required on the backdated replacement service authorization.
Approval by the manager or medical director must be documented in the paper case file before the replacement service authorization is issued. If no approvals were required for the original service authorization or the new service authorization, then no additional approvals are required.
Staff must document the need for the backdated replacement service authorization in a case note before generating the replacement SA. The comments section of the backdated replacement service authorization must reference the original SA number.
