First, check your insurance card and enrollment records to identify your coverage type. The table below shows options during the regular annual enrollment period. Current coverage Possible change Conditions to check Original Medicare Switch to Medicare Advantage Enrollment in Part A and Part B, and residence in the plan's service area Original Medicare with separate Part D Keep, change, or drop Part D Coverage for your medications and whether you have other prescription drug insurance Original Medicare without separate Part D Enroll in Part D Enrollment in Part A or Part B Medicare Advantage Switch to another Medicare Advantage plan Whether prescription drugs are included and the rules for using health care providers Medicare Advantage Return to Original Medicare Whether you can enroll in separate Part D coverage and Medigap Original Medicare is basic coverage through Part A and Part B. Part A is hospital insurance, and Part B is medical insurance. With Medicare Advantage, you receive basic coverage through a private plan. Part D is prescription drug coverage. You must live in the new plan's service area. If a plan has special enrollment requirements, check those too. Initial enrollment in Part A and Part B is a separate process from changing plans in the fall. Comparing plans and applying through Medicare Plan Finder Accurate medication and pharmacy information makes cost comparisons useful. Check estimated annual drug costs as well as monthly premiums. You can prepare and apply in this order. Read your current plan's notice of changes. The Annual Notice of Change, or ANOC, describes changes for the following year. Mark the 2027 premium and coverage changes. If you did not receive it, request it from your current plan. Gather the information you need to compare plans and apply. Check your Medicare card for your enrollment number and coverage start date. List the names, dosages, quantities, and refill schedules of your medications. Prepare a list of the pharmacies and health care providers you use. Compare 2027 plans in your area. Check the ZIP code and coverage year in Medicare Plan Finder. Enter your medications and pharmacies, then compare costs by plan. Also check whether your health care providers participate in each plan. Apply to your chosen plan during the enrollment period. You can select Enroll for that plan on the comparison screen. For enrollment by phone, contact 1-800-MEDICARE. The phone number is 1-800-633-4227. Check your application record and coverage start date. Save the application confirmation screen or confirmation number. Check that your enrollment confirmation names the plan you chose. Changes made during annual enrollment start on January 1, 2027. The role of the ANOC is explained in the Medicare notice of changes guide. You can find online and phone enrollment methods in Joining a plan. What to check on the comparison screen Estimated costs for the same medication vary by plan and pharmacy. Compare plans using the same pharmacy. Review medical service costs separately from drug costs. Item to check What to look for Monthly premium The monthly payment for the selected 2027 plan Deductible The amount you pay before insurance starts paying Copayment and Coinsurance Fixed amounts or percentages you pay for care or prescriptions Prescription drug coverage Whether medications are covered at the listed names and dosages Costs by pharmacy Estimated drug costs at the pharmacy you will use Estimated annual costs Which premiums and drug costs are included Rules for using health care providers Whether your primary care doctor, specialists, and hospitals participate in the plan Out-of-pocket limit for medical costs The coverage and limit under Medicare Advantage If you imported a medication list, compare it with the medications you currently take. A medication prescribed once in the past may still be on the list. This is a step to clean up your entries, not advice to stop or change a medication. See the CMS guide to adding drugs and pharmacies for instructions. Comparing national average premiums with your actual costs CMS national averages are not the premiums you will be billed. Actual amounts vary by where you live and the plan you choose. The following figures are CMS projections for 2027. Measure 2026 monthly average Projected 2027 monthly average Overall weighted average Medicare Advantage premium 14.37 U.S. dollars 12.00 U.S. dollars Average total premium for stand-alone Part D 35.09 U.S. dollars 36.00 U.S. dollars Part D premium portion of Medicare Advantage plans that include drug coverage 11.32 U.S. dollars 7.00 U.S. dollars The last row reflects Medicare Advantage rebates. The three rows measure different groups and use different calculations. Do not add them together to estimate your personal monthly premium. The figures come from the CMS announcement of 2027 premium projections. Applying the figures to your personal budget Use the actual quote for your chosen plan in your personal budget. Even if you enroll in Medicare Advantage, the Part B premium is a separate item. You may also have out-of-pocket costs when you receive care or fill prescriptions. Check the Medicare costs guide for the cost structure. Budget item Information to use Plan premium The chosen plan's 2027 premium Part B premium The official premium notice that applies to you Prescription drug costs Estimated costs using your medications and pharmacy Medical care costs The plan's out-of-pocket costs for each type of care Separate supplemental insurance costs An individual quote for Medigap or other coverage you plan to buy Do not add premiums again if they are already included in an annual estimate. Do not treat estimated prescription drug costs as your total medical costs. Your actual spending will also change if the care and prescriptions you need change. Employer and retiree insurance and family coverage If you have employer or retiree insurance, check your family's coverage before making changes. Enrolling in separate Medicare drug coverage may affect your existing insurance. In some cases, coverage for a spouse or dependents may end too. Ask your insurance benefits administrator how changes would affect coverage. Tell them you are considering separate Part D or Medicare Advantage enrollment. Check whether each family member's coverage will continue. Check coverage for your spouse and dependents as well as yourself. Keep the notice about whether your prescription drug coverage qualifies. Check whether your existing insurance is creditable coverage. This means prescription drug coverage that meets Medicare's standards. If you have creditable prescription drug coverage, you may not need to enroll in Part D as well. A gap in coverage can lead to a late enrollment penalty later. Discount cards do not replace prescription drug insurance. See the guide to existing prescription drug coverage for details. Returning to Original Medicare and Medigap rules Returning to Original Medicare does not guarantee that you can enroll in Medigap. Medigap is private insurance that supplements the out-of-pocket costs of basic coverage. The fall annual enrollment period is different from the protected Medigap enrollment period. Item Applicable rule Initial Medigap enrollment protection period under federal rules 6 months starting with the month Part B begins, if you are at least 65 After the protected period Health-based review, denial of enrollment, or different premiums may apply Separate protected enrollment rights May apply in certain situations or under state law Before deciding to return, check whether you can enroll in Medigap. You can also check with your state insurance authority for additional protected rights. Consider whether you need separate Part D coverage as well. The rules are explained in the guide to preparing to buy Medigap. Common mistakes about enrollment periods The fall change period and the change period early in the year apply to different people. Do not assume the same options will remain available if you miss the December deadline. Check which period applies to you. Common confusion Correct distinction Apply in fall 2027 because the coverage is for 2027 Choose coverage for January 2027 in fall 2026 Changes can be requested starting October 1 Plan information becomes available October 1; annual enrollment starts October 15 All enrollees can freely make changes early in the year The early-year Medicare Advantage change period is for people already enrolled in Medicare Advantage Reapply every year to keep the same plan Reapplication is generally unnecessary if your current coverage continues Keeping a plan means its coverage stays the same Premiums, drug coverage, and rules for using services may change the following year January 1 to March 31, 2027, is a separate change period. People already enrolled in Medicare Advantage can use it. They can switch to another Medicare Advantage plan or return to Original Medicare. Changes generally take effect on the first day of the month after the request is received. A move or loss of existing coverage, among other circumstances, may create a special enrollment period. Eligibility and deadlines vary by reason. Check your situation in the special enrollment periods guide. FAQ Q. When is the annual enrollment period for 2027 coverage? A. It runs from October 15 to December 7, 2026. The plan must receive your application by December 7. Changes made during this period take effect on January 1, 2027. Q. Can I apply to make changes in early October 2026? A. You can apply during the annual enrollment period starting October 15. You can compare 2027 plan information starting October 1. If you qualify for another enrollment period, check its requirements separately. Q. What should I have ready for Medicare Plan Finder? A. Have your ZIP code and a list of your medications and pharmacies ready. Check the dosages and quantities of your medications, too. When you apply, you will need your Medicare number and coverage start date. Q. Can I compare plans without a Medicare account? A. You can enter your medications and pharmacies to compare plans without logging in. However, you need an account to save the list you enter. Q. Can I keep my current plan? A. If your current coverage continues, you generally do not need to re-enroll. However, check the ANOC for changes in the coming year. Decide whether to keep the plan based on its 2027 terms. Q. Are all 2027 Medicare Advantage premiums $12 per month? A. $12.00 per month is CMS's projected national weighted average. It is not the amount an individual will be billed. Check the plan you choose, any separate premiums, and out-of-pocket terms for your actual costs. Q. Will choosing a plan with a low premium reduce my total costs? A. You cannot tell whether your total costs will decrease from the premium alone. You also need to compare medication costs and out-of-pocket costs for medical care. Check whether you can see the healthcare providers you need. Q. If I return to Original Medicare, can I also enroll in Medigap? A. Eligibility to enroll is not automatic. Check whether you have a Medigap initial enrollment protection period or other protected rights. Ask your state insurance authority about any additional rights under state law. Q. What should I check first if I have employer or retiree insurance? A. First, check how enrolling in a new plan will affect your existing insurance. Coverage for your spouse or dependents may also be affected. Contact your insurance administrator before making changes. Q. If I miss December 7, can I make the same changes in January? A. Not all the same options will be available. The early-year change period is for people already enrolled in Medicare Advantage. A special enrollment period requires a separate qualifying reason. Q. Where can I get help if applying online is difficult? A. You can call 1-800-MEDICARE at 1-800-633-4227. Your local SHIP also offers free, personalized counseling.
