Plain-words guide

My drug moved to a higher tier — what does that mean and what can I do?

Drug plans group medications into tiers — the higher the tier, the more you pay. Tier changes are announced in your September ANOC letter and take effect January 1. A drug moving from a fixed-copay tier (say, $42) to a coinsurance tier (a percentage of the drug's price) can multiply what you pay. You have three main options: switch to a plan that keeps the drug on a lower tier during open enrollment (October 15 – December 7), ask your doctor about a covered alternative, or request a formulary exception from the plan with your doctor's support.

How to see it coming

The ANOC's drug list section shows next year's tier for each covered drug. Compare it against what you pay now — a one-tier move on a drug you take monthly compounds twelve times a year.

Formulary exceptions

If no covered alternative works for you medically, your prescriber can ask the plan to cover the drug at a lower tier or at all. Plans must answer a standard exception request within 72 hours, 24 hours if expedited. Denials can be appealed.

Common questions

Why do plans move drugs between tiers?

Plans renegotiate prices and formularies annually. Tier placement reflects those contracts, not your medical need — which is why exceptions exist.

Can the plan change tiers mid-year?

Generally maintenance changes require notice, and if you're already taking the drug, many changes can't apply to you until the new plan year. Check the notice the plan sends.
