PEIP is a coordination of care model. Members must choose a primary care clinic and most care is handled or referred by the clinic, based on their care system protocols. Specialists require a referral, except OBGyn, Mental Health, Chemical Dependency, Chiropractic Care and Routine Vision, provided the practitioner is part of the self-referral network of their carrier. Members choosing HealthPartners-owned clinics can go to any HealthPartners-owned clinic without a referral.
