In 2026, a number of health insurance plans are reshuffling their drug formularies — removing some medications entirely, bumping others to higher cost tiers, or adding new hoops to jump through like prior authorization and step therapy. If you rely on a brand-name medication for a chronic condition such as asthma or HIV, these changes could hit your wallet hard.
Understanding what's happening — and knowing your options — can make a real difference.
What Is a Medication Formulary?
A formulary is simply the list of prescription drugs a health plan agrees to cover. Medications on this list are organized into tiers, and the tier a drug sits in determines how much you pay out of pocket. Generally speaking, the higher the tier, the higher your share of the cost.
Health plans revisit these lists regularly, factoring in things like:
- Clinical effectiveness — Is there strong evidence the drug works?
- Cost-effectiveness — How does it compare to similar medications?
- New alternatives — Has a generic or biosimilar entered the market?
- Updated clinical guidelines — Has medical guidance shifted?
Beyond tier placement, plans may require step therapy — meaning you'd have to try a lower-cost drug first before they'll approve the one your doctor originally prescribed. Others may require prior authorization, where your doctor must get formal approval before you can fill the prescription.
How to Check Whether Your Medication Is Still Covered
If you take maintenance medications for a long-term condition, it's worth building a habit of checking your formulary at the start of each year. Here's how:
- Use your plan's online drug search tool. Most insurers have a "Drug Search" or "Formulary Search" feature on their website, often found under the pharmacy section. Enter your medication's name to see if it's still covered, what tier it's in, and whether any restrictions apply.
- Download the formulary PDF. Many plans publish a full formulary document that spells out tier changes, step therapy requirements, and quantity limits. It's denser reading, but it's comprehensive.
- Call the member services number on your insurance card. A representative can walk you through any changes that affect your specific medications and explain what your new costs might look like.
- Use real-time prescription price tools. These resources can give you a clearer picture of what you'd pay at the pharmacy under your current plan.
Plans are required to notify members about significant formulary changes — but smaller updates, like adding a generic alternative, may not trigger a formal notice. Don't wait to find out at the pharmacy counter.
Can You Request an Exception?
If your medication has been removed from your plan's formulary, moved to a more expensive tier, or placed under new restrictions, you may be able to file a formulary exception request. This is a formal ask for your plan to cover the drug under better terms.
Here's what the process generally looks like:
- Talk to your doctor first. They'll need to submit a supporting statement explaining why you need the specific medication and why alternatives wouldn't work as well for you.
- Document your history. If you've already tried other drugs in the same class and experienced side effects or inadequate results, that evidence strengthens your case.
- Know the timelines. For standard exception requests, most plans must respond within 72 hours. If your situation is urgent, an expedited request typically requires a response within 24 hours.
If your exception is denied, you generally have the right to appeal. Your doctor can help you build a stronger case by providing additional clinical documentation.
What If Coverage Isn't Enough?
Even with insurance, rising tiers and new restrictions can make medications genuinely unaffordable. And for people who are uninsured or underinsured, a formulary shake-up can feel impossible to navigate alone.
That's where prescription assistance programs come in. Many pharmaceutical manufacturers offer a manufacturer assistance program — sometimes called a patient assistance program — that provides free brand-name medication or steeply discounted drugs to qualifying patients. These programs exist specifically to give prescription help for uninsured and underinsured individuals who can't afford their medications at retail prices.
If you're struggling with the cost of a brand-name drug, brand name drug financial assistance through these programs may be available to you — you just need to know where to look and how to apply.

Frequently Asked Questions
What Happens If My Exception Request Is Denied?
A denial isn't necessarily the end of the road. You typically have the right to file a formal appeal. Work with your doctor to gather additional clinical evidence — records of past treatments, documented side effects, or letters of medical necessity — to support your case.
What Kind of Evidence Does My Doctor Need to Provide?
The most persuasive evidence usually includes documentation that you've already tried comparable medications and they either didn't control your condition adequately or caused problematic side effects. The goal is to show that the excluded drug isn't a preference — it's a medical necessity.
What Does It Mean When a Drug Moves Up a Tier?
A tier change can mean a meaningful jump in what you pay. For example, a medication moving from a preferred tier to a non-preferred tier might shift your copay from $45 to $90 or more per fill — and for specialty drugs, the difference can be far greater. Always check your plan's cost-sharing structure so you're not caught off guard.
