Medicare Open Enrollment 2027: A Retiree’s Checklist Before December 7
7 min read · October 19, 2026 · EFC Wealth Management
Medicare Open Enrollment runs from October 15 through December 7, 2026, and changes you make generally take effect on January 1, 2027. If you do nothing, most plans renew automatically, but the plan that fit this year may cost more, cover less, or no longer be offered next year.
For retirees, Medicare is more than a health insurance decision. Premiums, deductibles and income-based surcharges come out of the same budget as Social Security, pension income and portfolio withdrawals. Reviewing your options carefully may help you avoid paying for coverage that no longer fits your needs.
“Does my current Medicare coverage still fit my health needs, my budget and my retirement income plan for 2027?”
Key takeaways
- Open Enrollment closes December 7, 2026. Most changes take effect January 1, 2027.
- The Part D out-of-pocket cap rises to $2,400 and the standard deductible to $700 in 2027.
- Compare total annual cost, including premiums, deductibles, copays and drug costs, not just the monthly premium.
- Medicare premiums are linked to income, so coverage decisions and retirement income planning are best reviewed together.
What is changing in Medicare for 2027?
As of October 19, 2026, several cost changes are confirmed for 2027, while others are projections that CMS is expected to finalize in November.
| Item | 2026 | 2027 | Status |
|---|---|---|---|
| Part D out-of-pocket cap | $2,100 | $2,400 | Confirmed |
| Part D standard deductible | $615 | $700 | Confirmed |
| Part B standard premium | $202.90/mo | About $209.50/mo | Projected |
| Part B deductible | $283 | About $292 | Projected |
| Social Security COLA | 2.8% | 3.6% | Confirmed |
Figures as of October 19, 2026, from AP reporting on 2027 Medicare changes, the 2026 Medicare Trustees Report (projections) and Kiplinger. Projected amounts may differ from final CMS figures.
1Prescription drug costs are rising
The annual cap on Part D out-of-pocket drug spending increases by $300, and the standard deductible rises by $85. A temporary federal program that helped hold down Part D premiums also ends this year, so many standalone drug plans may cost more in 2027.
2Medicare Advantage plans are shifting
Some plans are leaving certain areas, trimming extra benefits such as dental coverage, or raising copays. Read your plan's Annual Notice of Change carefully, even if you were satisfied with it this year.
3Your Social Security raise may be smaller than it looks
According to the Social Security Administration, as reported by the AP, the 3.6% COLA adds roughly $75 a month for the average beneficiary. Because most enrollees have the Part B premium deducted from their benefit, a premium increase may offset part of that raise.
Your 7-step Medicare Open Enrollment checklist
Use these steps to organize your review and prepare informed questions before December 7.
- Read your Annual Notice of ChangeYour plan sends this each fall. It lists 2027 changes to premiums, deductibles, copays, covered drugs and provider networks.
- Check your prescriptionsConfirm each drug is still on the formulary, at what tier, and whether it now needs prior authorization.
- Confirm your doctors and hospitalsNetworks can change, especially with Medicare Advantage HMO and PPO plans.
- Compare total annual costAdd premiums, deductibles, expected copays and drug costs. Depending on how much care you use, a $0-premium plan may cost more overall.
- Use the Medicare Plan FinderThe official tool at Medicare.gov lets you enter your drugs and pharmacies and compare estimated yearly costs.
- Weigh Medigap vs. Medicare AdvantageYou can return to Original Medicare during Open Enrollment, but a Medigap insurer may ask health questions. California residents have an annual "birthday rule" window to switch Medigap plans.
- Budget for the full yearNote dental, vision, hearing and travel needs, and set aside a healthcare line in your 2027 budget for costs Medicare does not cover.
Missed December 7? If you are already in a Medicare Advantage plan, the Medicare Advantage Open Enrollment Period from January 1 to March 31 allows one change to another Advantage plan or a return to Original Medicare. Options outside these windows are limited.
How Medicare connects to your retirement income and taxes
Medicare costs are tied to your income, so your plan choice and your financial plan are best reviewed together.
1IRMAA surcharges
Higher-income retirees pay an Income-Related Monthly Adjustment Amount on top of standard Part B and Part D premiums. Premiums for 2027 are based on 2025 modified adjusted gross income (MAGI), as reported on your 2025 tax return. Exceeding a bracket threshold by even one dollar can increase premiums for the full year.
2Withdrawals, Roth conversions and capital gains
Large IRA withdrawals, Roth conversions, required minimum distributions or the sale of appreciated investments may push MAGI into a higher IRMAA tier two years later. Coordinating the timing of these decisions is part of tax-aware planning.
3Life-changing events
If your income dropped because you retired, lost a spouse or divorced, you may be able to request an IRMAA reduction from Social Security using form SSA-44.
4Budgeting for healthcare
Premiums, deductibles, dental, vision, hearing and possible long-term care all draw from retirement income. Building these into your income plan may help you prepare for these costs over a retirement that could last several decades.
Please note: EFC does not provide tax advice. Consult a qualified tax professional about your situation.
Common Open Enrollment mistakes to avoid
- Letting your plan auto-renew without reading the 2027 changes
- Choosing a plan by monthly premium alone
- Assuming you can always switch back to Medigap without health questions
- Overlooking how a one-time withdrawal or asset sale may affect future premiums
- Assuming the best plan for one spouse fits the other
- Sharing your Medicare number with unsolicited callers
