Medicare Open Enrollment 2027: What New Jersey Pre-Retirees and Retirees Need to Know

Why This Year’s Open Enrollment Matters More Than Usual

Every fall, Medicare’s Annual Enrollment Period (AEP) gives you a window to review your coverage and make changes for the coming year. For 2027, the Medicare open enrollment window runs from October 15 through December 7, 2026. Changes you make during this period take effect on January 1, 2027.

This year’s enrollment period carries extra weight. A temporary federal program that held down Part D premiums is ending after 2026, which means prescription drug costs may shift meaningfully for many beneficiaries. At the same time, the annual out-of-pocket cap on prescription spending is rising, Part B premiums are projected to increase, and some Medicare Advantage plans in South Jersey may be narrowing their provider networks or adjusting benefits.

Whether you are already on Medicare or approaching eligibility, the team at GPS Wealth Management encourages you to treat this enrollment window as an active planning opportunity rather than something to ignore.

Key Enrollment Dates to Know

What Is Changing for 2027

Part B Premiums

The standard Medicare Part B premium is projected to rise from $202.90 per month in 2026 to approximately $209.50 in 2027. CMS typically announces the official figure in late October or November. Part B covers doctor visits, outpatient services, preventive care, and durable medical equipment.

Part D Prescription Drug Costs

This is where the most significant changes are happening:

• Base premium increasing: The national base beneficiary premium is projected to climb from $38.99 per month in 2026 to approximately $41.33 in 2027. Your actual Part D premium depends on the plan you choose.
• Premium subsidy ending: A temporary federal program under the Inflation Reduction Act that limited premium increases for stand-alone Part D plans is sunsetting after 2026. Without this support, many beneficiaries may see higher premiums when they receive their 2027 plan notices.
• Out-of-pocket cap rising to $2,400: The annual cap on prescription drug out-of-pocket spending is increasing from $2,100 in 2026 to $2,400 in 2027. Once you reach this threshold, you pay nothing more for covered prescriptions for the rest of the year.
• Standard deductible rising: The Part D deductible is projected to increase from $615 in 2026 to approximately $700 in 2027.

These changes mean that even if you were satisfied with your Part D plan last year, the cost structure may look different for 2027. Reviewing your plan’s formulary against your current prescriptions is worth the time.

Medicare Advantage Changes

CMS has set Medicare Advantage capitation rates for 2027 at only a 0.09% increase, well below the rate of medical cost inflation. In practice, this may mean some Medicare Advantage plans in the South Jersey market could reduce supplemental benefits, narrow provider networks, or increase copays for specialist visits. The only way to know for certain is to read your plan’s Annual Notice of Change (ANOC), which arrives in September.

Income-Related Monthly Adjustment Amount (IRMAA)

If your modified adjusted gross income exceeded certain thresholds on your 2025 tax return, you will pay a surcharge on top of the standard Part B and Part D premiums. This is called the Income-Related Monthly Adjustment Amount, or IRMAA. IRMAA uses a strict two-year lookback, so your 2025 income determines your 2027 premiums.

CMS has not yet released the official 2027 IRMAA brackets, but projections suggest thresholds will rise by roughly 2.7% to 3.7% over 2026 figures. For 2026, the baseline thresholds are:

This is where retirement income planning and Medicare planning intersect. A Roth conversion in 2025, a capital gain from selling a home, or a large IRA distribution can push income above the threshold and trigger IRMAA surcharges two years later. The team at GPS Wealth Management works with clients to coordinate Roth conversion strategies and tax-efficient withdrawal planning with IRMAA awareness so that a smart tax move today does not create an unexpected Medicare cost two years from now.

What to Review During Open Enrollment

Your plan’s Annual Notice of Change (ANOC) and Evidence of Coverage (EOC) documents arrive each September. These outline exactly what is changing for the coming year. Here is what to focus on:

1. Prescription Drug Formulary

Plans can move medications between formulary tiers or remove them entirely. If you take maintenance medications, check whether they are still covered at the same tier and copay level for 2027. Also check whether your pharmacy remains in the plan’s preferred network, as using an out-of-network pharmacy can mean significantly higher costs.

2. Provider Network

If you are in a Medicare Advantage plan, confirm that your primary care physician, specialists, and preferred hospital system remain in-network for 2027. Network changes are one of the most common reasons people switch plans during open enrollment.

3. Total Cost of Coverage

Do not look at the monthly premium alone. Compare total annual costs, including the premium, deductible, copays, coinsurance, and the out-of-pocket maximum. A plan with a lower premium may have higher copays for specialist visits or imaging. The Medicare Plan Finder tool on Medicare.gov lets you enter your prescriptions and providers to estimate total annual costs across available plans in your ZIP code.

4. Medicare Advantage vs. Original Medicare

Open enrollment is the one time each year you can move between Medicare Advantage and Original Medicare with a standalone Part D plan. There is no single right answer here. Medicare Advantage plans typically offer lower premiums and additional benefits (dental, vision, hearing), but come with network restrictions. Original Medicare with a Medigap supplement offers broader provider access and more predictable costs, but at a higher monthly premium. Your health needs, preferred providers, and budget all factor into this decision.

Late Enrollment Penalties: Why Timing Matters

If you are approaching 65 and do not yet have Medicare, be aware that delaying enrollment without qualifying coverage can result in permanent penalties added to your premiums:

• Part B penalty: 10% of the standard premium for each full 12-month period you were eligible but did not enroll. This surcharge is permanent and applies for as long as you have Part B.
• Part D penalty: 1% of the national base beneficiary premium for each full month you went without creditable prescription drug coverage. For 2026, that base is $38.99, so 24 months without coverage would add approximately $9.40 per month to your premiums permanently.

If you are still working at 65 and covered by an employer group health plan (through your own or a spouse’s employer with 20 or more employees), you generally qualify for a Special Enrollment Period when that coverage ends. But if the employer has fewer than 20 employees, Medicare becomes the primary payer at 65, and delaying enrollment can trigger penalties. The team at GPS Wealth Management helps clients approaching 65 map out the Medicare enrollment timeline alongside their broader retirement planning checklist.

New Jersey-Specific Medicare Considerations

Free Medicare Counseling Through NJ SHIP

New Jersey operates the State Health Insurance Assistance Program (SHIP), which provides free, unbiased Medicare counseling. Trained volunteers can help you compare plans, understand your options, and resolve billing issues. SHIP counselors do not sell insurance or recommend specific plans. Counseling is available by phone, virtually, or in person through your county’s Office on Aging.

The NJ Medicare Hotline is 1-800-792-8820. During open enrollment season (October through early December), appointment slots tend to fill quickly, so scheduling early is recommended.

Medigap Protections in New Jersey

New Jersey is one of the states that offers Medigap (Medicare supplement) open enrollment protections beyond the federal minimum. If you are enrolled in Original Medicare and want to purchase a Medigap policy, New Jersey law provides a six-month open enrollment period starting when you turn 65 and enroll in Part B, during which insurers cannot deny coverage or charge higher premiums based on health conditions. Missing this window can make Medigap coverage significantly more expensive or harder to obtain.

NJ FamilyCare and Medicare Savings Programs

If your income is limited, New Jersey offers Medicare Savings Programs that can help pay Part B premiums, deductibles, and coinsurance. The NJ FamilyCare program may also provide additional coverage. Your county Board of Social Services can determine eligibility.

How Medicare Fits Into Your Broader Retirement Plan

Medicare is one piece of retirement income planning, not a standalone decision. The team at GPS Wealth Management considers Medicare costs and strategies within the full picture:

• IRMAA and income management: Coordinating Roth conversions, RMD timing, and capital gains to stay below IRMAA thresholds where possible. See the team’s guide to required minimum distributions for how RMDs can affect Medicare costs.
• Healthcare costs in retirement: A 65-year-old couple may spend $315,000 or more on healthcare throughout retirement, according to Fidelity’s 2024 estimate. Medicare premiums, Medigap or Advantage plan costs, dental and vision expenses, and potential long-term care needs all factor into how much you need to retire in New Jersey.
• Social Security timing: Because IRMAA is based on modified adjusted gross income, the timing of Social Security benefits can influence Medicare costs. Delaying Social Security may allow for more aggressive Roth conversions in early retirement while keeping IRMAA at bay. See the team’s guide to when to claim Social Security.
• Tax-efficient withdrawals: New Jersey does not tax Social Security benefits, which creates planning opportunities around the NJ pension exclusion and retirement account withdrawal sequencing. The team’s guide to tax-efficient retirement withdrawals covers how to coordinate these decisions.
• Long-term care planning: Medicare does not cover long-term custodial care. If you are in your 50s or 60s, this is the time to evaluate long-term care insurance or hybrid policies. The team at GPS Wealth Management has a detailed guide to long-term care planning in New Jersey.

Your Open Enrollment Action Steps

Here is a practical checklist to work through before December 7:

• Review your ANOC: Read the Annual Notice of Change from your current plan. Flag any formulary, network, or cost changes.
• List your medications: Note the name, dosage, and frequency of every prescription you take. You will need this for the Medicare Plan Finder.
• Use Medicare Plan Finder: Enter your ZIP code, prescriptions, and preferred pharmacy at gov/plan-compare to compare plans side by side.
• Check provider networks: If you are considering a Medicare Advantage plan, confirm your doctors and hospitals are in-network for 2027.
• Calculate total costs: Compare total annual cost (premiums + deductible + copays + coinsurance), not just the monthly premium.
• Consider IRMAA: Review your 2025 income to anticipate whether you will face surcharges. If a life-changing event reduced your income, you may be able to request an IRMAA reduction through SSA Form SSA-44.
• Schedule SHIP counseling: If you want a second opinion, call 1-800-792-8820 to book a free session with a trained Medicare counselor.
• Mark the deadline: December 7 is a firm cutoff. Changes made after this date will not apply until the next enrollment period.
