Frequently Asked Questions

Do all marketplace plans cover the same drugs?

No. While all plans must cover at least one drug per USP category, the specific drugs covered and their tier placement vary by insurer and plan. Two Silver plans from different companies may have very different formularies. Always check the specific formulary for each plan you are considering.

What is the cheapest marketplace plan for prescriptions?

It depends on your specific medications. Gold and Platinum plans have lower copays but higher premiums. Silver plans with CSR subsidies (for households earning 100% to 250% of the federal poverty level) often provide the best overall value for prescription drugs. Use Healthcare.gov to enter your drugs and compare total costs.

Are weight loss drugs covered on marketplace plans?

Most marketplace plans do not cover weight loss medications, as they are not considered an essential health benefit. However, some insurers are voluntarily adding coverage for FDA-approved anti-obesity drugs with prior authorization. Check individual plan formularies during open enrollment.
