NPI: NPI Reminder: Reauthorization TARs with Legacy Provider Numbers

April 2, 2009

Retroactive to November 1, 2008, Medi-Cal requires the use of Medi-Cal-registered National Provider Identifiers (NPIs) on all Treatment Authorization Requests (TARs). TARs being updated for reauthorization with the legacy provider number will be deferred or denied. Although logging into eTAR allows you to inquire and update TARs submitted with a legacy provider number, it does not override the legacy provider number with the NPI number. Therefore, if the date of service and units on a TAR need to be extended, and the eTAR or paper TAR was originally submitted with a legacy provider number, a new eTAR or paper TAR will need to be submitted using the NPI number. When submitting a new TAR with the NPI, providers should reference the previous TAR number and state the need for reauthorization in the “Miscellaneous TAR Information” field.

Note:

This also applies to other general TAR updates. Providers should check if a legacy provider number was used on the original submission before requesting an update. If a legacy provider number was originally used on the TAR, a new TAR will need to be submitted with an NPI number instead of requesting an update to the original TAR.
