An end of year medicare checklist is the simplest way to stop leaving money and coverage on the table. Medicare runs on the calendar year. On January 1, deductibles reset, drug spending totals go back to zero, and most Medicare Advantage extras vanish unused. Millions of beneficiaries never touch dental allowances, vision credits, or over-the-counter cards they already paid for through their premiums.
Meanwhile, the annual enrollment window closes December 7. Missing it locks you into the same plan for another twelve months. Families helping an aging parent feel this pressure most acutely. A short list of tasks, done in October and November, prevents almost every common year-end mistake.
What Actually Resets on January 1
Understanding the reset is the foundation of any end of year medicare checklist. The Part B deductible is $283 in 2026. Once you meet it, Medicare pays 80% of the approved amount for most outpatient care. That progress disappears at midnight on December 31. If you have already satisfied it, scheduling a needed procedure in December rather than January can save real money.
Prescription coverage works the same way. The Part D out-of-pocket cap sits at $2,100 for 2026, and the deductible cannot exceed $615. Beneficiaries who reach the cap enter catastrophic coverage and pay nothing more for covered drugs that year. However, that clean slate returns in January. For example, filling a scheduled refill in late December while you are in the catastrophic phase costs far less than the same fill on January 5.
Medicare Advantage supplemental benefits are the biggest source of forfeited value. Plans from UnitedHealthcare, Humana, Aetna, Cigna, and Blue Cross affiliates commonly bundle dental, vision, hearing, fitness, and OTC allowances. These allowances almost never roll over. Some reset monthly or quarterly. Others expire December 31 entirely.
Deadlines and Windows You Cannot Miss
Timing drives everything. Medicare’s Annual Enrollment Period runs October 15 through December 7 every year. Your plan must receive the request by December 7. Changes then take effect January 1. During that window you can switch Advantage plans, return to Original Medicare, add or drop Part D, or move between drug plans.
Before that, watch your mailbox. Plans must send an Annual Notice of Change by September 30. It lists next year’s formulary, network, cost sharing, and benefit changes. Typically it is the single most ignored document in Medicare. Read it. Drug formularies shift constantly, and a medication covered this year may sit on a higher tier next year.
| Window | Dates | What You Can Do |
|---|---|---|
| Annual Notice of Change | Arrives by Sept 30 | Review next-year plan changes |
| Annual Enrollment Period | Oct 15 – Dec 7 | Switch or drop any MA or Part D plan |
| Benefit use deadline | Through Dec 31 | Spend dental, vision, OTC allowances |
| Medicare Advantage Open Enrollment | Jan 1 – Mar 31 | Change MA plans once or return to Original Medicare |
The January window matters as a safety net. Anyone enrolled in a Medicare Advantage plan on January 1 gets one additional change between January 1 and March 31. In most cases it is a second chance, not a substitute for careful fall shopping, because Medigap underwriting rules may still apply if you return to Original Medicare.
Your Practical End of Year Medicare Checklist
Work through an end of year medicare checklist in a single sitting. Start with the calendar. Call your dentist, optometrist, and audiologist in October, not December. Appointment books fill fast in the final weeks, and an unused cleaning or eyewear allowance cannot be recovered.
Next, log in to your plan portal and find your remaining allowance balances. Check the expiration rule for each one. OTC cards often expire quarterly, so a balance sitting there in early December may already be a partial loss. Then confirm you have used your yearly wellness visit, which Medicare covers once every 12 months at no cost when the provider accepts assignment. The Part B deductible does not apply to it.
Third, run your drug list through the Plan Finder at Medicare.gov Plan Compare. Enter every medication and your preferred pharmacy. The tool ranks plans by total annual cost, not premium alone, which is the number that actually matters. As a result, many people discover a lower-premium plan would cost them more overall.
Finally, verify your doctors remain in network for next year, and check whether you qualify for the Extra Help program through the Social Security Administration. Free one-on-one counseling is available from your State Health Insurance Assistance Program. SHIP counselors are trained volunteers, take no commissions, and can be reached through SHIP National Technical Assistance Center. Organizations like AARP and Mutual of Omaha publish supplementary comparison material, but unbiased state counseling remains the safest starting point.
Common Mistakes an End of Year Medicare Checklist Prevents
The most expensive mistake is autopilot. Roughly two-thirds of beneficiaries never compare plans during enrollment, according to research from KFF. Plans change every year. Staying put is a decision, not a default.
Another frequent error involves marketing calls. CMS finalized new rules in April 2026 tightening how Medicare Advantage and Part D plans are rated, marketed, and paid. Even so, aggressive outreach spikes each fall. No legitimate representative will pressure you to decide immediately or ask for your Medicare number by cold call.

A third mistake is treating the December 7 deadline as flexible. It is not. Requests received December 8 are generally rejected outside of a qualifying special enrollment period, such as a move, a loss of employer coverage, or a chronic condition qualification. Working through an end of year medicare checklist by mid-November leaves a comfortable buffer for paperwork problems.
Documentation helps too. Keep your Medicare Summary Notices and Explanation of Benefits statements. They show what you actually spent and whether a claim was denied in error. Appeals have strict timelines, and a denial from October is far easier to fix in November than in March.
Frequently Asked Questions
Do unused Medicare Advantage dental and OTC benefits roll over to next year?
Almost never. Most allowances expire at the end of the plan year, and many OTC cards reset monthly or quarterly instead. Check your Evidence of Coverage for the exact expiration rule.
Should I schedule surgery in December or wait until January?
If you have already met your Part B deductible, December is usually cheaper. Both the deductible and your Part D spending totals restart January 1. Discuss timing with your provider and confirm the procedure is medically appropriate.
What if I miss the December 7 deadline entirely?
Medicare Advantage enrollees get a second window from January 1 through March 31 to make one change. Original Medicare and standalone Part D members generally must wait, unless a special enrollment period applies. An end of year medicare checklist completed in early November avoids the problem.
Where can I get free, unbiased help with my end of year medicare checklist?
Contact your state SHIP program for no-cost counseling. Medicare’s own helpline at 1-800-MEDICARE operates 24 hours a day. Neither charges you, and neither sells insurance.
