AI Summary

UnitedHealthcare Community Plan of Washington is updating their primary care attribution process to reassign Medicaid patients to the PCPs most actively involved in their care. Starting January 1, 2026, they will perform quarterly 24-month claim look-backs to determine patient-provider relationships and may reassign patients accordingly.

Action Required

By January 1, 2026: Primary care practices should prepare for potential patient roster changes as UnitedHealthcare may reassign Washington Medicaid patients based on 24-month claim history.
