No-Cost Services Available at All Montana One Health Clinic Locations For State Plan Members

State Plan members have been able to access comprehensive health care at One Health clinics in Miles City, Glendive, and Ashland.

We are excited to announce that starting March 1, 2023, the partnership between the State Plan and One Health is expanding to include the Chinook, Hardin, Harlem, and Lewistown locations!

Additional information

Labs – Lab services ordered by a One Health provider have no out-of-pocket expense. Outside provider lab orders are not accepted. To have labs drawn at One Health with no out-of-pocket expense, make an appointment with a One Health provider to have labs ordered.


Health ScreeningsState-Sponsored Health Screenings are not provided at One Health clinics. Premise Health (Montana Health Centers) remains the source for State-Sponsored Health Screenings. To earn the Live Life Well Incentive you will need to schedule an appointment at a Montana Health Center or attend an off-site event.


In-House Pharmacy – No copay or coinsurance for prescription drugs prescribed by a One Health provider and dispensed by a One Health in-house pharmacy (Glendive (coming August 2023) Hardin, Lewistown, and Miles City locations).

For clinic locations without a pharmacy, One Health can mail prescriptions (non-controlled, non-refrigerated) directly to plan member. The regular copay and coinsurance applies for a prescription drug filled at the One Health pharmacy that is not prescribed by a One Health provider. Likewise, a prescription written by a One Health provider but filled by another community or hospital pharmacy will apply to regular benefits.


Dental – Regular dental benefits apply to dental services available in Lewistown, Harlem, and Miles City locations. This means any dental services from this clinic will be submitted to Delta Dental and regular deductible and coinsurance will apply.
