Medicare Open Enrollment runs from October 15 to December 7 each year, and it’s your chance to review, switch, or drop your Medicare Advantage or Part D prescription drug plan. Ignoring this window could cost you money or coverage.

Plan costs and benefits change yearly. Your current plan might raise premiums, change its drug list, or drop providers from its network. Even if you’re happy with your plan, it’s smart to double-check that it still meets your needs for 2026.

In 2026, average premiums for stand-alone Part D plans are expected to drop slightly to $39.50. Medicare Advantage plans with drug coverage may offer even lower premiums through rebates, but they may also come with more limited provider networks or stricter approval rules.

Take time to confirm your doctors are in-network, your prescriptions are covered, and your preferred pharmacy is included. Reviewing your options could help you save money and avoid surprises next year.
