What Is a Formulary?
A formulary is a list of prescriptions that are included in your health insurance plan. It’s a list of generic (more affordable versions of brand-name drugs) and brand-name medicines that your health insurance plan will help pay for. Plans create this list to make sure you have access to safe, effective drugs without breaking the bank.
Why Is a Formulary Important?
Formularies aren’t just random lists—they help keep healthcare affordable and smart. Here’s why they matter:
- Control Costs: They guide doctors to prescribe more affordable options that work just as well, saving money for everyone.
- Ensure Quality: The list focuses on drugs proven to be safe and effective, especially for common needs like pain relief, mental health, or chronic conditions.
- Cover Your Needs: For special groups, like people on Medicare or Medicaid, formularies must include at least two drugs per category (like for heart health or depression). This helps health plan members with ongoing issues, such as mental health or addiction, get what they need without extra hassle.
If your plan doesn’t have a well-rounded formulary, you could face surprises like high bills for meds you rely on. For instance, if you take medicine for anxiety or diabetes, a less robust formulary might force you to switch to something less ideal or pay more.
What are Formulary Tiers?
Formularies are usually split into levels called tiers. For example:
- Tier 1: Often generics with the lowest cost to you (example: a small copay of $5–$10).
- Tier 2: Preferred brand-name drugs with a medium cost.
- Tier 3 or higher: Specialty or non-preferred drugs that might cost you more out of pocket.
A team of doctors and pharmacists from the insurance company reviews and updates this list based on new drugs, safety info, and costs. If a medicine isn’t on the list (called non-formulary), you might have to pay full price yourself—which can add up fast!
Did you know?
A health insurance company may have a few different formularies. These formularies apply to different types of plans available for different members, such as members who purchase their own coverage through the Marketplace or members who are on employer-sponsored plans offered by their workplace. Remember to check the formulary to make sure you are consulting the right one when you are viewing the medications available.
Why Check the Formulary When Shopping for a Plan?
If you’re shopping for a new coverage, you can check the formularies for the health insurance plans you’re considering on the websites of the companies that offer them. Here’s why:
- Matches Your Needs: If you take certain meds to manage your health, make sure they’re covered by the plans you are considering. Switching plans could mean your go-to prescription costs more if it’s not in the formulary.
- Fits Your Budget: A plan with a strong formulary could save you hundreds on prescriptions every year. High-tier drugs can hit your wallet hard.
- Avoids Gaps: Some plans have limited coverage for drugs that treat conditions such as behavioral health medications (for mental health or addiction). Checking the formulary ensures you won’t get stuck paying out of pocket or jumping through hoops like prior authorization from your insurance company.
Pro tip: Formularies can change from year to year, so be sure to review them during open enrollment.
How to Check a Formulary
If you need to check whether or not a drug is included in your formulary:
- Visit your insurance company’s website or app and search for “drug list” or “formulary”.
- Search for your medications by name to confirm if they’re included in the formulary.
- If your prescription is not covered, ask your doctor about alternatives or file an exception request with your insurance company.
