Washington Medicaid: Updates to primary care attribution process

We’ve updated our attribution process to help ensure UnitedHealthcare Community Plan of Washington patients are assigned to the primary care provider (PCP) most actively involved in their care.

Effective Jan. 1, 2026, we’ll perform quarterly 24-month claim look-backs to determine if a member has been regularly engaged with a non-assigned PCP. If you are currently seeing patients who are not assigned to your practice, we may reassign these patients to you. We hope this change will lead to better health outcomes and more efficient care management. 

Claim look-back exclusions

Primary care codes received from the following facilities will be excluded from the claim look-back and not considered for member reassignment:

• Comprehensive inpatient rehabilitation facility
• Emergency room hospital
• Inpatient hospital
• Inpatient psychiatric facility
• Pharmacy
• Urgent care

Specialties that may have attribution

The following practitioner specialties may have attribution:

As we update and align PCP attribution, you may see a higher than usual shift in the January 2026 roster listing. We expect that subsequent quarterly roster updates to reflect a lower number of changes.
