One Health Clinics - Health Care and Benefits Division
One Health Clinics
State Plan members have access to comprehensive primary care at eligible One Health Clinic locations in Montana.
- Services at eligible One Health Clinics have no additional out-of-pocket costs.
- Access to many of the services available at One Health Clinics hinges on you having a primary care relationship with a One Health provider. Establish care with a One Health provider to be eligible for no co-pay and no out-of-pocket on prescriptions and labs.
- Only services provided at the One Health Clinics have no out-of-pocket cost. Services provided by another facility or provider will apply to regular State Plan benefits, even if a One Health Clinic provider refers you.

State Plan members may only access the One Health Services listed at Montana-based One Health Clinic locations.
No copay or coinsurance for eligible prescription medications. Talk with your One Health provider to see if your medications qualify for this benefit.
- To qualify for no- or reduced-copayment, medications must be prescribed by a One Health provider, dispensed by a One Health pharmacy, and billed through Navitus (State of Montana Pharmacy Benefit Manager).
- Regular copay and coinsurance will apply 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.
- This benefit does not cover GIPs and GLP-1s.
One Health pharmacies are in the Glendive, Hardin, Lewistown, and Miles City One Health locations. If you attend a clinic location without a pharmacy, One Health can mail prescriptions (non-controlled, non-refrigerated) directly to the plan member.
Most routine lab services can be completed with no out-of-pocket expense at a One Health clinic.
-
A One Health provider must order lab services; outside provider lab orders are not accepted.
