St. Luke’s Health System will begin offering a Medicare Advantage plan in Idaho starting in 2027. This move comes as Saint Alphonsus Health System plans to exit the state’s Medicare Advantage market.
Why it matters
The health system aims to remove financial barriers to patient care through its new MA-PD HMO plan. This expansion occurs as several national insurers, including UnitedHealthcare and Humana, are reducing their Medicare Advantage footprint in Idaho.
St. Luke's Health Plan currently serves 65,000 members across its various health products. The upcoming Medicare Advantage plan will be available in seven Idaho counties and features $0 copays for primary, mental health, and preventive care.

Market Landscape
St. Luke's expansion directly offsets the exit of other major health entities from the state's Medicare Advantage market. This move allows the local system to capture market share left behind by national insurers like UnitedHealthcare and Humana.
Residents in the seven eligible counties will have access to a new insurance option featuring $0 copays for primary and preventive care. This may provide a stable coverage alternative for patients impacted by other insurers leaving the Idaho market.
The takeaway
Patients considering their options for 2027 should monitor the specific county eligibility for the new plan as it becomes available. This development highlights a shift toward local providers stepping in to manage Medicare Advantage coverage as national players reduce their presence.
