Part D drug plans in Missouri

9 standalone Part D prescription drug plans are available statewide in Missouri for 2027, with monthly premiums starting around $5.30. Every Part D plan caps your out-of-pocket drug costs at $2,400 for the year. The plan that’s cheapest for you depends on your exact prescriptions and pharmacy. See our Part D guide.

Missouri’s Medigap anniversary rule

Missouri gives Medicare Supplement policyholders a protection most states don’t. Each year, within 30 days before or after your policy’s anniversary date, you can switch to the same Medigap plan letter with a different insurance company. There are no health questions. If your Plan G premium has crept up, you may be able to move to a lower-priced Plan G without medical underwriting.

Your anniversary date is usually the date your current Medigap policy started. Mark it on your calendar. We can shop it for you about 45 days ahead.
