TAR and eTAR Processing Clarification
Providers may not update paper Treatment Authorization Requests (TARs) using the electronic Treatment Authorization Request (eTAR) system. Once a TAR has been started using the paper process, it must be continued in the same manner to avoid complications with adjudication.
Providers may submit a new eTAR, before the expiration of a paper TAR, to reauthorize the services, as long as there is no overlap of service dates from one TAR to another. Providers may continue to update existing eTARs online through the eTAR process.
