Millions of Americans can change their Medicare coverage during the annual enrollment window, with new choices taking effect at the start of the year. Medicare open enrollment for 2027 runs from Oct. 15 to Dec. 7, and the costs beneficiaries face may shift even as average Medicare Advantage premiums are expected to decrease.
Check the details. Enrollees can review traditional Medicare, Medicare Advantage and Part D prescription drug coverage, then switch plans or move between traditional Medicare and Medicare Advantage.
The changes selected during the window take effect on Jan. 1. Beneficiaries can also switch Medicare Advantage plans or choose a different Part D prescription drug plan.
Read the plan notice closely
Yahoo Finance reported that people should review the Annual Notice of Change, or ANOC, letter explaining what their plan will change for 2027. The letter should have arrived the previous month, according to the report.
Juliette Cubanski, director of the program on Medicare policy at KFF, told Yahoo Finance that plan changes can go beyond premiums. “There are changes beyond premiums underneath the hood, including cost-sharing and coverage of benefits, which means it's important to read the fine print,” she said.
About 7 in 10 people with Medicare do not comparison shop during open enrollment, according to the report. Cubanski said many people stay with their current plan unless it is withdrawn or its premium changes substantially. Comparing options can feel overwhelming, she said, leading some beneficiaries to sit out the process.
That choice can leave people unaware of shifts in what they pay for care or which benefits remain covered. Reviewing the notice and comparing the services a person expects to use can reveal changes that a premium alone does not show.
Medicare Advantage costs and options
Medicare Advantage plans, offered through private companies as an alternative to traditional Medicare, cover more than half of Medicare enrollees, or about 36 million people, Yahoo Finance reported. Average premiums are expected to decrease in 2027, but that does not necessarily mean beneficiaries will pay less overall.
Kim Lankford, author of “Medicare 101,” told Yahoo Finance that enrollees should examine copayments and other out-of-pocket costs for the care they use, expected procedures and hospital stays. She also urged them to check whether their doctors are covered and how the plan handles out-of-network providers.
Medicare Advantage PPOs usually offer some out-of-network coverage at higher copayments, while HMOs usually do not cover out-of-network providers except for emergencies, Lankford said.
The maximum out-of-pocket cost for covered in-network Medicare Advantage services in 2027 will be $9,850, up from $9,250. For combined in-network and out-of-network services, the maximum will be $14,800, up from $13,900, according to Yahoo Finance.
Those limits matter because a lower monthly premium does not tell beneficiaries what they could owe when they need treatment. Plans may also include extras such as prescription coverage, eyeglasses, dental care and fitness classes, but the report said some are trimming those benefits as provider costs rise.
Changes can be less obvious than removing a benefit altogether. A plan might lower its annual dental coverage maximum or stop covering certain expensive procedures, including dental implants, Lankford said.
Plan availability is also narrowing. The average Medicare beneficiary has 28 Medicare Advantage prescription drug plan options for 2027, down from 31 this year, according to a KFF analysis cited by Yahoo Finance. Some plans are ending coverage in local markets, which could leave beneficiaries with fewer choices or require them to find new coverage.
