Summary
Tufts Health One Care will transition from a Medicare-Medicaid Plan to a Dual Eligible Special Needs Plan (D-SNP) on January 1, 2026. Members will receive new ID cards with different member ID numbers, but all active prior authorizations remain valid and no provider action is required.
Action Required
By January 1, 2026: Update billing system and front desk procedures to recognize new Tufts Health One Care member ID card format and numbers for D-SNP members. Verify eligibility using new member IDs when checking benefits. No changes needed for existing prior authorizations as they remain valid through the transition.
