The Medicare Open Enrollment period (October 15–December 7, 2025) is not just another routine renewal window—it’s your once-a-year opportunity to review and adjust your healthcare coverage before 2026. And this year, major changes to premiums, prescription drug costs, and Medicare Advantage networks mean the difference between saving hundreds or overpaying by thousands.
“Beneficiaries can’t afford to take a passive approach this year,” warns Dr. Emily Carson, a senior policy analyst at the Kaiser Family Foundation. “The 2026 changes are far-reaching—especially for those managing high drug costs or enrolled in Medicare Advantage.”

Part B Premium and Deductible Increases
The Centers for Medicare & Medicaid Services (CMS) is projecting a notable cost uptick for 2026.
- Standard Monthly Premium: Approximately $206.50, up significantly from 2025.
- Annual Deductible: Expected to rise to about $288.
For many retirees, this represents hundreds in extra annual costs — even before factoring in copays and prescription expenses.
“Even beneficiaries who don’t change their coverage will see cost increases in 2026,” notes Thomas Reid, a Medicare consultant based in Washington, D.C. “Budgeting now is key.”

Medicare’s Income-Related Monthly Adjustment Amount
Medicare’s Income-Related Monthly Adjustment Amount (IRMAA) adds surcharges to both Part B and Part D premiums for higher earners. Here’s how it works
- IRMAA for 2026 is based on 2024 income, as reported on your tax return.
- If your Modified Adjusted Gross Income (MAGI) was high in 2024 due to capital gains, retirement withdrawals, or property sales, your premiums may jump substantially.
| MAGI (Individual) | MAGI (Joint) | Monthly Part B Premium (Approx.) |
|---|---|---|
| $103,000 or less | $206,000 or less | $206.50 |
| $103,001–$129,000 | $206,001–$258,000 | $290.00 |
| $129,001–$161,000 | $258,001–$322,000 | $380.00 |
| $161,001–$193,000 | $322,001–$386,000 | $470.00 |
| Over $193,000 | Over $386,000 | $560.00+ |
Saving Strategy:
If your income has fallen since 2024 due to retirement, divorce, or other life events, you can appeal your IRMAA through the Social Security Administration (SSA) using Form SSA-44. This may reduce your premiums dramatically.
Part D Prescription Drug Reform: The $2,100 Cap
The Inflation Reduction Act (IRA) continues to overhaul Medicare Part D, reshaping how much beneficiaries pay for prescriptions.
$2,100 Annual Cap: Starting in 2026, your total out-of-pocket drug spending will be capped at $2,100 per year (up slightly from $2,000 in 2025). Once you hit this limit, you’ll pay $0 for covered medications for the rest of the year.
Formulary Coverage: This cap only applies to drugs covered by your plan’s formulary. Medications that require prior authorization or are excluded won’t count toward your cap.
| Feature | 2025 | 2026 |
|---|---|---|
| Annual Out-of-Pocket Cap | $2,000 | $2,100 |
| Insulin Copay Cap | $35/month | $35/month |
| Vaccines | Free | Free |
| Deductible (Max) | $545 | ~$615 (projected) |
“Even with the cap, plan selection matters,” emphasizes Dr. Laura Nguyen, a senior health economist at AARP. “The wrong Part D plan could still cost you thousands more if your drugs fall into higher tiers.”
Saving Strategy: Use Medicare’s Plan Finder tool to compare formularies and tier structures. A slightly higher premium may save you money if it better covers your specific prescriptions.
New Option: Medicare Prescription Payment Plan (MPPP)
Beneficiaries with expensive prescriptions can opt into the Medicare Prescription Payment Plan (MPPP), allowing them to spread out out-of-pocket costs through monthly installments instead of paying large sums early in the year.
- Enrollment is voluntary and available through your Part D plan.
- Ideal for beneficiaries managing chronic or high-cost conditions.
Medicare Advantage (Part C)
Medicare Advantage remains popular for its low premiums and extra benefits, but beneficiaries should brace for shrinking networks and scaled-back perks.
Watch Out for These 2026 Changes
- Higher Copays & Premiums: Many Advantage plans are raising out-of-pocket limits.
- Reduced Benefits: Expect cuts to dental, vision, or OTC allowances.
- Narrower Networks: Hospitals and doctors may be dropped without much notice.
“The most expensive mistake retirees make is not reading their Annual Notice of Change (ANOC),” warns Nancy Taylor, a licensed Medicare broker. “A doctor you’ve seen for years might not be in your network next year.”
Prior Authorization Pilot Expansion
In select states—Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington—Medicare will expand its prior authorization pilot to certain Original Medicare services. This means that some non-emergency, high-cost procedures (like MRIs, infusions, or outpatient surgeries) may require pre-approval even under Original Medicare.
Potential Risks:
- Delayed approvals or service denials.
- Added administrative steps for providers.
Recommendation: Ask your provider’s billing office to confirm if the procedure you need falls under prior authorization in your state.
Medigap (Medicare Supplement) Plans
Medigap plans help cover the out-of-pocket costs Original Medicare doesn’t pay, including deductibles and coinsurance.
2026 Focus: Rate Comparison and Switching Flexibility
Since Medigap benefits are standardized, the only difference between insurers is cost. For example, a Plan G from one insurer offers the same coverage as Plan G from another — but premiums may differ by hundreds of dollars annually.
Saving Strategies:
- Compare Premiums: Request updated quotes every year.
- Check State Rules: Some states have “Birthday Rules” allowing you to switch Medigap policies without medical underwriting.
- Plan Selection:
- Plan G/F: Covers most costs after you pay the Part B deductible.
- Plan N: Lower premiums, but small copays for doctor and ER visits.
| Plan | Premium Trend | What You Pay in 2026 |
|---|---|---|
| Plan G | Rising | Part B deductible ($288) |
| Plan N | Stable | $20 office copay, $50 ER copay, plus deductible |
“If you’ve been loyal to one Medigap insurer for years, you’re likely overpaying,” says Richard Hale, a senior Medicare analyst. “Switching to a lower-cost carrier offering the same standardized plan could save over $1,000 annually.”
Why These Changes Matter?
With inflation, rising healthcare costs, and new Medicare rules under the Inflation Reduction Act, 2026 could be one of the most financially consequential years for retirees in recent memory. The average beneficiary now faces higher premiums, tighter networks, and more complex drug coverage — but also greater opportunities for savings through smart plan selection.
“This open enrollment is not about autopilot—it’s about analysis,” said Dr. Carson. “Review your ANOC, your prescriptions, and your income. That’s how you protect your wallet in 2026.”
