How do I check a 2027 plan's drug coverage?
Look up the exact 2027 plan and its drug list, also called a formulary. Search for each medicine's name and strength, then check the plan's Summary of Benefits and Coverage and ask the insurer about your pharmacy and expected cost.
Marketplace plans cover prescription drugs as an essential health benefit, but that does not mean every brand, dose or medication is covered on every plan. A plan's name and insurer are not enough to confirm your prescription.
| Check | What to look for |
|---|---|
| Exact plan and year | Use the 2027 plan name or ID and the current formulary for that specific plan, not last year's list or another plan from the same insurer. |
| Medicine and strength | Check the prescribed name, strength and quantity. Ask the insurer and pharmacist if the drug entry is unclear. |
| Tier and cost | Ask about the copay or coinsurance, whether a deductible applies, and what you may pay at your pharmacy. |
| Restrictions | Check for prior authorization, step therapy, quantity limits or a required specialty pharmacy. |
| Pharmacy | Confirm that your preferred pharmacy is in the plan's network for the type of prescription you need. |
Keep the list for your own comparison or use the insurer's or Marketplace's tool. Do not post medication names, diagnoses or member numbers in a public form or chat.
What do drug tiers and deductibles mean for my cost?
A drug tier is a group in the plan's formulary that has its own cost-sharing rules. Plans can place the same medicine on different tiers. One plan may use a fixed copay, while another uses coinsurance, a percentage of the covered cost.
Ask whether the prescription is subject to a medical or separate drug deductible, and what you would pay before and after that deductible. The plan's actual price can depend on the pharmacy, quantity and other plan rules; a listed tier alone is not a price quote.
| Assumption | Plan A | Plan B |
|---|---|---|
| Monthly premium after any savings | $300 | $275 |
| Cost for one monthly refill | $20 | $50 |
| Twelve premiums plus twelve refills | $3,840 | $3,900 |
In this hypothetical example, the plan with the lower premium costs $60 more over the year for premiums plus this one medicine. The example assumes the stated refill amounts apply all year with no deductible and excludes other care, uncovered drugs and changing prices. It is not a quote; real plans and savings vary.
What if a medicine needs approval or is not listed?
Prior authorization means the plan must approve a drug under its rules before it pays for it. Step therapy can require trying another treatment first, and a quantity limit can restrict the amount covered. Ask the plan and your prescriber what applies to your specific prescription.
An approval under your old plan may not automatically carry over to a new one. If you are already taking a medicine, ask the new insurer and your prescriber what is needed before your current coverage ends. Some insurers may offer a one-time refill after enrollment, but do not assume yours will.
If a drug is not normally covered, ask about the plan's drug exceptions process. Your prescriber may need to explain why the medicine is appropriate. If the insurer denies the request, ask about your appeal rights and deadlines. Do not stop or change a prescribed medicine without talking with your prescriber.
Does the pharmacy I use matter?
Yes. Plans can use different pharmacy networks and may have different rules for retail, mail-order or specialty prescriptions. Confirm that the specific pharmacy you want is in the 2027 plan's network and ask what you would pay there.
The pharmacy or insurer can help you identify whether your prescription requires a specialty pharmacy. Also ask whether the medicine is handled through the pharmacy benefit or, for certain treatments, the medical benefit; the coverage and billing rules may differ.
When should I compare plans for 2027?
For HealthCare.gov, 2027 open enrollment runs November 1, 2026 through January 15, 2027. Choose a plan by December 15 and pay the first premium for coverage starting January 1. State-based Marketplaces may have different dates.
Review the drug list even if you intend to renew. Formularies, pharmacy networks and costs can change. Confirm the information with the insurer close to enrollment and ask how you will be notified of later changes.
