2.9 million people. That is how many Medicare Advantage enrollees are facing forced plan cancellations heading into 2026 — not because they chose poorly, but because their insurer decided to leave the market. A Johns Hopkins Bloomberg School of Public Health analysis, published as of June 19, 2026, put that figure at roughly one in ten Medicare Advantage participants. If you are approaching Medicare age or already enrolled, that number should make October 15 feel a great deal closer than it currently seems.
Google News surfaced original reporting from The Motley Fool outlining financial planning steps worth completing before Medicare's annual Open Enrollment window opens. This post synthesizes that guidance with official data from the Centers for Medicare & Medicaid Services (CMS) and independent research — because the cost picture for 2026 is more complicated than the surface-level headlines suggest.
What Is Happening With Medicare Costs in 2026
As of June 19, 2026, Medicare's pricing landscape is running in two opposite directions simultaneously. Medicare Part B — which covers most outpatient care and physician visits — costs $202.90 per month, according to CMS. That is a $17.90 increase, or 9.7%, from the 2025 rate of $185.00. The Part B annual deductible climbs to $283, up from $257 in 2025. CMS noted that Part B premiums would have been approximately $11 higher per month if not for regulatory action addressing unprecedented spending on skin substitutes, with projected spending expected to drop 90% — meaning the 9.7% increase already reflects some cost containment.
On hospital costs, the Medicare Part A deductible rises to $1,736 in 2026, an increase of $60 from $1,676 in 2025. On the prescription drug side, the Part D out-of-pocket cap is set at $2,100 for 2026, up from $2,000 in 2025. The Inflation Reduction Act continues to cap insulin costs at $35 per month for Part D enrollees and ensures recommended vaccines are covered at no cost — meaningful protections that remain in place regardless of which plan a beneficiary selects.
The contrast sharpens in private plan territory. Average monthly Medicare Advantage premiums are actually falling to $14.00 in 2026, down $2.40 from $16.40 in 2025. Standalone Part D monthly premiums are dropping to $34.50 on average, down $3.81 from 2025. CMS projects that 97% of Medicare beneficiaries will have access to 10 or more Medicare Advantage plan choices this enrollment season. The catch: lower average premiums have not stopped large insurers from exiting markets, creating the forced-disenrollment crisis that Johns Hopkins documented.
Chart: Monthly Medicare premium changes for 2026 vs. 2025. Part B rises $17.90/month while average Part D and Medicare Advantage premiums fall. The Part B increase alone adds $214.80 annually — more than the combined savings from lower Part D and MA averages. Source: CMS, as of June 19, 2026.
Why the Cost Math Is Trickier Than It Looks
A licensed Medicare broker, cited in The Motley Fool's coverage, put it plainly: "If you don't take a little time to compare options during open enrollment, you're probably leaving money on the table." A Medicare enrollment expert in the same reporting noted that beneficiaries can save "hundreds or even thousands of dollars by finding a prescription drug or Medicare Advantage plan that better meets their needs."
The arithmetic is worth running. Part B alone costs $214.80 more per year in 2026 than in 2025 ($202.90 x 12 vs. $185 x 12). If you are also on a suboptimal standalone Part D plan — paying the average $34.50 per month when a plan better matched to your specific drug list might cost considerably less — the annual loss compounds. Passive enrollment is expensive. The fall in average premiums is real, but it is an average across thousands of plans; your specific plan may have moved in the opposite direction.
One factor that catches higher earners off guard: IRMAA, or the Income-Related Monthly Adjustment Amount (a surcharge added on top of standard Part B and Part D premiums for beneficiaries above specific income thresholds). As of June 19, 2026, IRMAA now begins at $109,000 in individual income, up from $106,000 in 2025. Because IRMAA is calculated on income from two years prior, a recent retirement, job change, or other significant income drop may already qualify you for a lower tier — but only if you file a Life-Changing Event appeal with Social Security. That savings does not happen automatically.
The broader context matters too. More than 55% of eligible Medicare beneficiaries are now enrolled in Medicare Advantage, per CMS data current as of June 19, 2026. That majority status means insurer exits affect more people than traditional Medicare changes do — and makes it essential to verify that your specific plan is still operating in your county before you assume everything is fine.

How AI Is Entering the Medicare Plan Comparison Problem
The complexity of Medicare plan selection — dozens of plans per county, thousands of drug formulary combinations, shifting insurer footprints — is precisely the kind of problem where software can outperform a manual spreadsheet review. CMS appears to agree. On February 23, 2026, the agency issued a formal Request for Information seeking AI and machine learning tools to upgrade Medicare.gov's Plan Finder, including personalized claims-informed recommendations, predictive analytics for plan matching, real-time conversational chatbots, and natural language processing (NLP — software that reads complex documents and converts them to plain language). The agency's own RFI acknowledged that "current tools rely primarily on static comparison tables and documents that can be difficult to navigate, particularly for beneficiaries with limited health literacy, language barriers, or cognitive challenges."
Private companies have not waited for CMS to build those tools. Services like MedicareCopilot already score every Medicare plan across 12 factors and use NLP to surface benefits that keyword searches miss. This shift toward AI-assisted enrollment mirrors a broader pattern in healthcare financial planning — one that health analysts at NewSlens have tracked closely in the context of drug pricing and coverage disruption, where automated tools increasingly help beneficiaries navigate a system that was simply not designed for easy self-navigation.
4 Steps to Take Before October 15
As of June 19, 2026, IRMAA surcharges begin at $109,000 in individual income. But since IRMAA is based on income reported two years prior, a recent retirement, layoff, or other significant income event may entitle you to a lower surcharge tier right now — not at the next enrollment cycle. File a Life-Changing Event appeal using Form SSA-44 with Social Security before or during the enrollment window. Getting this right can reduce your monthly Part B premium burden immediately and does not require waiting until October. If your income did not change materially, this step takes five minutes to confirm and skip.
The 2026 Part D annual out-of-pocket cap stands at $2,100 — a hard ceiling on drug spending that represents a genuine protection for high-cost-drug users. But the cap only applies to drugs your specific plan covers at the right cost tier. Before October 15, list every prescription you currently take and run it through Medicare's Plan Finder or an AI-assisted comparison service to identify which plan's formulary covers your medications most economically. Insulin is capped separately at $35 per month, and recommended vaccines are covered at no cost — confirm both apply to any plan you are considering, not just in the marketing materials but in the actual formulary documentation.
With 2.9 million enrollees facing forced disenrollment — per Johns Hopkins Bloomberg School of Public Health data as of June 19, 2026 — this is not a hypothetical risk. Contact your current insurer directly before October 15 to confirm your plan will continue in your county next year. If your plan is being discontinued, a Special Enrollment Period gives you the right to switch outside the standard window. Do not wait for a mailed notice; call and confirm. Beneficiaries who receive discontinuation notices have additional time and options, but those options require active engagement, not passive waiting.
Open Enrollment runs October 15 through December 7, with any changes taking effect January 1. CMS is actively building AI-powered improvements into Medicare.gov's Plan Finder, but in the interim, supplement the official tool with an independent licensed broker consultation or an AI-powered service that can score plans against your specific drug list and provider network. If you miss the main window, the Medicare Advantage Open Enrollment Period — running January 1 through March 31, 2026 — allows one additional plan switch, but entering January on the right plan is far preferable. A 90-minute comparison session before October 15 is the most direct form of personal finance the Medicare system offers.
Frequently Asked Questions
When is Medicare open enrollment for 2026 coverage changes, and how does it work?
Medicare's annual Open Enrollment Period runs from October 15 to December 7 each year. During this window, beneficiaries can switch between Original Medicare and Medicare Advantage, change Medicare Advantage plans, or change standalone Part D prescription drug plans. All changes take effect January 1 of the following year. As of June 19, 2026, the Medicare Advantage Open Enrollment Period also runs from January 1 to March 31, 2026, allowing beneficiaries already enrolled in Medicare Advantage to make one additional switch if they missed the main window or need to course-correct after January 1.
Can I switch from Medicare Advantage to Original Medicare during open enrollment?
Yes. The annual Open Enrollment Period from October 15 to December 7 allows any enrolled beneficiary to switch between Medicare Advantage and Original Medicare (paired with a standalone Part D plan), switch between Medicare Advantage plans, or change Part D drug plans. As of June 19, 2026, 97% of Medicare beneficiaries have access to 10 or more Medicare Advantage plan choices, so the comparison exercise is worthwhile even if your current plan is not being discontinued. Beneficiaries whose plans are exiting the market receive a Special Enrollment Period with additional time and flexibility beyond the main window.
What happens if I miss the Medicare open enrollment deadline in December?
Missing the December 7 deadline without a qualifying special circumstance generally locks you into your current plan until the following open enrollment period. The Medicare Advantage Open Enrollment Period — January 1 through March 31 — provides a secondary window for one plan switch if you are already enrolled in Medicare Advantage, but coverage options are more limited than during the main enrollment period. Beneficiaries who receive formal notice that their plan is being discontinued are granted a Special Enrollment Period, which is why actively verifying your plan's status before October 15 is essential rather than waiting to see what arrives in the mail.
What is the Medicare Part B premium for 2026, and how does IRMAA affect what I actually pay?
As of June 19, 2026, the standard Medicare Part B monthly premium is $202.90 — a $17.90 increase from 2025's $185.00. The Part B annual deductible also rose to $283, up from $257 in 2025. However, beneficiaries with individual income above $109,000 (up from $106,000 in 2025) pay more than the standard premium due to IRMAA surcharges added on top. IRMAA is calculated using your tax return from two years prior, which means a recent income change will not automatically lower your surcharge — you must file a Life-Changing Event appeal with Social Security using Form SSA-44 to trigger a recalculation. Getting the IRMAA tier right can be worth hundreds of dollars annually.
Bottom line: In my read of the 2026 Medicare data, the surface story — "Medicare Advantage premiums are falling!" — masks what is actually happening to most beneficiaries' total annual costs. Part B alone is adding $214.80 per year compared to 2025, the insurer exit crisis is displacing nearly 3 million people who thought they had a stable plan, and the complexity of plan selection grows every enrollment cycle. The beneficiaries who come out ahead this October will not necessarily be the ones who spent the most time researching — they will be the ones who spent the right 90 minutes before December 7, ideally using AI-assisted tools that can surface what a static comparison table cannot. That is not financial optimism. That is the arithmetic of not leaving money on the table.
