As the leaves begin to change, it is also time for Medicare beneficiaries to take a fresh look at their health care coverage. Medicare Open Enrollment runs from October 15 through December 7, 2026, providing an annual opportunity to review existing coverage, compare available plans and make changes for 2027.
While it may be tempting to let your current plan renew automatically, taking time to review your options could lead to meaningful savings and help ensure your coverage continues to meet your needs. Insurance companies can adjust premiums, deductibles, prescription drug costs, provider networks and other benefits each year. A plan that worked well in 2026 may not be the most suitable option for 2027.
For many Medicare beneficiaries, the primary focus of Open Enrollment is Medicare Part D, which provides prescription drug coverage. Each year, insurance companies can change the medications included in their formularies, adjust prescription costs and modify their preferred pharmacy networks. A medication that was affordable this year could cost more next year, or a drug that was previously covered might move to a different pricing tier or no longer be included in the plan's formulary.
That is why it is important to review your current medications with the plan's updated coverage information. Pay attention to monthly premiums, deductibles, copayments and coinsurance, as well as whether your preferred pharmacy is still considered in-network. Comparing these details can help you avoid unexpected expenses and identify a plan that better fits your needs.
Even if you aren't currently taking prescription medications, having appropriate Part D coverage may still be important. Prescription drug coverage is not just about managing today's health care expenses; it can also help protect you from future penalties. Medicare generally requires beneficiaries who go without Part D coverage for an extended period to pay a late enrollment penalty when they eventually enroll, unless they qualify for an exception.
The penalty is generally calculated as 1% of the national base beneficiary premium for each full month you went without creditable prescription drug coverage after your initial enrollment period. The national base beneficiary premium was $38.99 per month in 2026 and will increase to $41.33 per month in 2027.
For example, someone who went for 15 full months without creditable prescription drug coverage could face a monthly penalty of approximately $5.80 using the 2026 base premium. Using the 2027 base premium, that same 15-month period would produce a penalty of approximately $6.20 per month. Medicare rounds the penalty to the nearest 10 cents, and the actual amount depends on the applicable calculation when coverage begins.
This penalty is generally added to the monthly Part D premium for as long as the individual has Medicare prescription drug coverage. Since the calculation uses the national base premium, the penalty can increase over time. This makes it worthwhile to understand your coverage options even if you currently have little or no need for prescription medications.
It is also worth remembering that you do not necessarily need to purchase a Medicare Part D plan if you already have other prescription drug coverage that Medicare considers creditable. Some employer-sponsored or other health plans may meet this standard. Before declining or dropping coverage, verify that your existing plan qualifies so you can avoid an unnecessary penalty later.
In addition to prescription drug plans, Open Enrollment provides an opportunity to evaluate Medicare Advantage plans, also known as Part C. These plans combine Medicare Part A and Part B coverage and often include prescription drug benefits, along with additional services such as dental, vision or hearing coverage. However, benefits, provider networks, referral requirements and out-of-pocket costs can vary considerably from one plan to another.
If you are enrolled in a Medicare Advantage plan, pay particular attention to the Annual Notice of Change you should receive from your insurance company. This notice outlines important adjustments to your plan for the coming year, including changes in premiums, copayments, deductibles, covered services and provider networks. Review this document carefully rather than assuming your coverage will remain the same.
For 2027, there are some noteworthy changes across Medicare plans. Federal projections indicate that average standalone Part D premiums are expected to increase modestly, while average Medicare Advantage premiums are projected to decline. However, these are national averages, and your individual plan's costs and benefits may change differently depending on the insurer and where you live. That is another reason to compare your specific options rather than relying on general headlines.
Open Enrollment is also a good time to consider how your overall health care needs may be changing. Perhaps you have started taking new medications, anticipate additional medical appointments or want access to a different network of providers. These changes can influence which plan makes the most financial and practical sense for your situation.
Ultimately, Medicare decisions should involve more than simply choosing the plan with the lowest monthly premium. A plan with a low premium could have higher deductibles, more expensive prescriptions or greater out-of-pocket costs when you need medical care. Looking at your estimated total annual health care expenses, rather than focusing on one cost alone, can provide a more complete picture.
The most important step this fall is to review your 2027 plan notices and compare your options before the December 7 deadline. Medicare's Plan Finder at Medicare.gov allows you to compare available health and prescription drug plans, estimate medication costs and review coverage details. You can also contact our office, and we will be happy to assist you with finding a plan that best fits your needs,
Remember that changes made during Open Enrollment generally take effect January 1, 2027. If you decide your current coverage still meets your needs, you can usually keep your existing plan without taking further action. But making that decision after reviewing your options is very different from simply allowing your plan to renew without checking for changes.
A brief review each fall can help you avoid surprises, identify potential savings and make more informed decisions about your health care expenses. Taking a little time now may provide both financial benefits and peace of mind in the year ahead.
