The cost of your medications depends on your plan and the tier your medication is placed on. Please see your plan documents for the pricing of your medications. Our plans have five tiers: Preferred Generic, Non-Preferred Generic, Preferred Brand, Non-Preferred Brand, and Specialty. The lowest tier (tier 1) will have the least expensive copay. The highest tier (tier 5) will have the most expensive copay. If you have questions about the cost of your medications, please call 1-833-975-1281.

You can fill your medications at any in-network pharmacy up to a 30-day supply. Our pharmacy network is broad, and you can find a pharmacy near you with our Idaho pharmacy directory or within the pharmacy portal. Maintenance medications (anything over a 30-day supply) can be filled at St. Luke’s outpatient pharmacies or St. Luke’s Mail Order Pharmacy.

St. Luke's Health Plan does not require High Deductible Health Plan (HDHP) participants to meet their deductible prior to covering medications in some categories. If you are enrolled in an HDHP, you will not have to meet your deductible before the Plan contributes to the cost of your prescription for medications listed in the categories below. These medications are designated as "PREV" in the Prescription Drug List (2024 List | 2025 List). Medications in the following categories are included:

• Anticonvulsants
• Asthma and COPD
• Brand Contraceptives
• Cardiovascular (including cholesterol, blood pressure and blood thinners)
• Diabetes (Insulin, Non-Insulin, and Test Strips)
• Mental Health (antipsychotics and antidepressants)
• Osteoporosis

If your medication requires prior authorization, your doctor will need to send additional information to St. Luke’s Health Plan prior to the plan covering the medication. This is to help save you money and ensure we are safely using medications. Refer to the Prescription Drug List (2024 List | 2025 List) for a list of medications that require prior authorization. Please ask your doctor to call 1-833-975-1281 to obtain the required forms to start the prior authorization process.
