Medicare open enrollment ends December 7: what seniors should consider

“There’s really no one who can’t benefit from at least taking some time to take a look,” said Alex Cottrill, senior policy analyst with KFF’s Medicare policy program.

Those enrolled in Medicare Advantage or Part D prescription drug plans typically receive an “Annual Notice of Change” in September detailing any modifications. Jessica Rivkin, vice president of Reliance Medicare Advisors, emphasizes the importance of reviewing current plans, even without receiving such a notice.

With the enrollment deadline approaching December 7, seniors have a limited time to make informed decisions.

One key consideration is choosing between traditional Medicare and Medicare Advantage, a private insurance option. Traditional Medicare requires separate enrollment in a Part D prescription drug plan and Medigap coverage, while Medicare Advantage combines these into a single plan.

“You only have to pick one plan rather than having these modular options that you have in traditional Medicare,” Cottrill explained.

Medicare Advantage plans may restrict provider networks, potentially leading to higher out-of-pocket costs for out-of-network care. Cottrill advises verifying provider coverage for those considering Medicare Advantage, and understanding the implications for Medigap coverage.

Switching back to traditional Medicare after enrolling in Medicare Advantage may result in higher premiums due to age or pre-existing conditions.

A helpful resource is Plan Finder, a tool from the Centers for Medicare & Medicaid Services (CMS) for comparing plans and checking provider networks. However, independent verification with providers and plans is recommended.

For general information, individuals can contact 1-800-Medicare or consult their State Health Insurance Assistance Program. Brokers can also provide assistance, but potential commission-based incentives should be considered.

Changes made during open enrollment take effect January 1, 2027. Medicare Advantage enrollees have a separate enrollment period from January 1 to March 31 to switch plans or return to original Medicare. Individuals facing specific circumstances, such as relocation or loss of coverage, may qualify for special enrollment periods.

“This can be a really complicated decision for some people, so take the time to get comfortable with the questions you have, what you need in 2027, and make sure that you’re getting all of your needs covered,” Rivkin advised.
