Summary

Effective January 1, 2026, Massachusetts SCO and One Care members who lose MassHealth Medicaid eligibility will have only Medicare benefits covered during a 60-day deeming period. Providers must verify eligibility through the UnitedHealthcare portal and will not be reimbursed for Medicaid-only services during this period.

Action Required

Action needed
Immediately: Billing team must verify member eligibility through UnitedHealthcare Provider Portal before providing services to SCO/One Care members. Check if Medicaid shows inactive with end date indicating deeming period. Stop billing Medicaid-only services (adult foster care, day habilitation, chore services, home-delivered meals, etc.) for members in deeming period. Establish separate payment agreements with members if continuing non-Medicare covered services. Update billing workflows to distinguish between Medicare-covered and Medicaid-only services.
