UIS Transition TAR Submission Process: Guidance for Medi-Cal Providers

Effective date
Nov 1, 2026
Identified
Oct 31, 2026

Summary

Effective November 1, 2026, Medi-Cal fee-for-service providers must use a new UIS transition TAR submission process via the Medi-Cal Provider Portal's eTAR application for members transitioning from Managed Care Plans with existing MCP authorizations. Providers must select the special handling option 'UIS transition where MCP authorization exists,' include service dates, and are not required to submit supporting medical documents or complete all standard TAR fields.

What to do

Action · 8 steps
01Starting November 1, 2026: Billing and prior authorization staff must implement the new UIS transition TAR workflow in the Medi-Cal Provider Portal.
02Before submitting any UIS transition TAR, confirm that a valid MCP authorization exists on file.
03When submitting UIS transition TARs electronically via eTAR, select the special handling option 'UIS transition where MCP authorization exists' on the Patient Information page.
04Include 'from' and 'thru' dates of service.
05Do not submit paper TARs—only electronic submissions via the Portal are accepted.
06For members without existing MCP authorizations, continue using the standard TAR process.
07Training should emphasize that supporting medical documents are not required for UIS transition TARs and that required fields after the miscellaneous TAR information section may be bypassed by selecting Cancel.
08Monitor DHCS provider bulletins and FAQs for updates, and contact the Telephone Service Center at 1-800-541-5555 with questions.
