Formulary
A plan formulary is a comprehensive list of generic and brand-name prescription drugs covered under your health plan, designed to promote safe, effective, and affordable drug therapy.
The formulary categorizes the drugs into tiers. Drugs in the lowest tier cost the least, while drugs in higher tiers, like specialty medications, cost more. All the drugs in your plan formulary are approved based on safety, quality, and cost-effectiveness.
Your plan formulary:
- Is easy to search
- Includes information about the medication
- Includes special considerations about the prescription, if they apply

Preferred retail pharmacy
A preferred retail pharmacy can provide up to a 90-day supply of prescription drugs. In most cases, if you choose a preferred retail pharmacy, you will pay less when filling a 30- to 90-day supply of medication. This is because Providence Health Plan has worked with the pharmacy to lower the cost of medication copays for our members.
If you have medications that you take regularly, called maintenance medications and value (or preventive) drugs, you need to get them from either an in-network mail-order service or a preferred Retail 90 pharmacy. Getting a 90-day supply at a preferred pharmacy saves money because you pay only 2 copays instead of 3. Plus, value drugs can have a $0 copay when you use in-network mail order service or a preferred Retail 90 pharmacy, except CVS or Rite Aid.
