If you enroll as a State Plan Retiree, you and your spouse/domestic partner and/or dependent’s Medicare Part D prescription drug coverage will be provided by the State Plan. If you are enrolled on State Plan coverage, you may not purchase Medicare Part D coverage with any other provider. If you enroll in other Medicare Part D coverage, all of your State Plan coverage (medical, prescription, vision, dental, and life) will be terminated. The Big Sky Rx Program is dedicated to helping Medicare clients pay for Medicare approved prescription drug insurance premiums.

You can get a three month (90-day) supply of some maintenance medication for a two month copay!
The State Plan pays less for many medications when a 90-day supply is filled at an in-network retailer or preferred mail order pharmacy. We pass those savings on to you by reducing your copay.
Preferred 90-Day Supply Options
- Most in-network retail pharmacies (refer to network directory at navitus.com)
- Costco (membership not required)
- Ridgeway
Please note controlled substances are only available at a 34-day supply.
Lumicera Health Services is the State Plan’s preferred pharmacy to handle specialty medications (drugs that require special administration). Delivery of your specialty medications is free, and direct to your door or prescriber's office via FedEx.
Using a pharmacy other than Lumicera for specialty medications could cost significantly more and does not accumulate toward your prescription annual Max Out-of-Pocket.
The tiers on the formulary are structured as follows:
- Tier 0: Certain preventative medications.
- Tier 1: Low-cost, high-value generics and select brands that provide high clinical value. These products are the lowest-net cost for the plan and the lowest copayment for the member.
- Tier 2: Preferred brands and select generics that are less cost effective.
- Tier 3: Non-preferred brands and generics that provide the least value because of high cost or low clinical value, or both.
Prescription Max Out-of-Pocket: Individual $1,800 / Family $3,600
