Prescription Drug Coverage

Prescription drug coverage is the benefit within your health insurance plan that helps pay for medications prescribed by a licensed provider. Under the ACA, prescription drugs are one of the 10 Essential Health Benefits — all Marketplace plans are required to cover them, though what’s covered and how much you pay varies by plan.

Your plan’s formulary is the list of covered drugs organized into cost tiers. How much you pay for a prescription depends on:

  • Which tier the drug falls on (generic drugs cost less; specialty drugs cost more)
  • Whether you’ve met your deductible (some plans require it, others apply drug copays before)
  • Whether the pharmacy is in your plan’s network
  • Whether the drug requires prior authorization

Using a generic drug instead of a brand-name equivalent almost always saves money. Generics contain the same active ingredients and are FDA-approved as equivalent — ask your doctor or pharmacist if a generic version is available.

Mail-order pharmacies (offered by many plans) often provide 90-day supplies at a lower cost per dose than 30-day retail fills. If you take a maintenance medication regularly, ask your insurer about mail-order options.

Frequently Asked Questions

How do I know if my prescriptions are covered before I enroll?

Check your plan’s formulary before enrolling. Your insurer’s website or HealthCare.gov’s plan comparison tool has a drug search feature. Enter your medications to see which tier they fall on and what your estimated cost would be. If a medication you take isn’t listed, it may not be covered — factor that into your plan choice.

Does my prescription spending count toward my out-of-pocket maximum?

Possibly, but the rules vary by plan and drug. ACA plans must apply your drug spending toward your out-of-pocket maximum if the drug is covered. However, some plans have separate drug deductibles that must be met before cost-sharing kicks in. Manufacturer coupons and patient assistance programs can help with specialty drug costs, but check whether your plan’s out-of-pocket counting rules apply to third-party payments.
