Medicare Open Enrollment Isn't Until Fall - But Here's What to Do Right Now to Prepare

Medicare Open Enrollment may not start until October, but waiting until then often leads to rushed decisions and missed details. Plan benefits, provider networks, and drug coverage can shift year to year, sometimes in subtle ways that only show up when it's too late. Taking time now could help you avoid wasting your retirement savings and reduce the risk of unpleasant surprises later.

Think of May as your preparation window. A little organization now might make fall enrollment far less stressful, and help you make the right moves when it counts. Here's where to start.

Start with a simple plan checkup

Before comparing new plans, take a good look at your current one. Many people assume that coverage doesn't change much year to year, but this isn't always the case.

Pull out your most recent plan documents and review monthly premiums, out-of-pocket costs, drug formulary changes, and provider network updates. If you've had unexpected bills this year, that's a signal that something may not be working as well as you thought.

Track how you actually use health care

It's easy to pick a plan based on what you think you'll need. It's smarter to use real data. Over a few months, keep a simple running list of doctor visits, specialists you see, prescriptions, lab work, and procedures. This helps you see how you're really using your health care plan.

Due to the new prescription drug cap, some enrollees with high drug costs may hit it for the first time, which can significantly change health care costs.

Patterns are important. A plan that looked affordable last year might not fit your current health needs anymore. This step alone could help you avoid money mistakes during enrollment.

Understand what may change for next year

Medicare plans change annually. Even if your plan worked well this year, there is no guarantee it will look the same in 2027. Watch for changes to out-of-pocket maximums, which will shift from $2,100 this year to $2,400 in 2027, as well as adjustments to drug tiers.

Your current provider will send you an Annual Notice of Change (ANOC) by late September. Reading this document is the single most important step in your fall preparation.

Learn the basics of Special Enrollment Periods

You don't always have to wait until the fall. Certain life events may qualify you for a Special Enrollment Period (SEP), which allows you to change plans outside the standard window.

Common Special Enrollment Period triggers are moving to a new service area, losing other insurance coverage, or qualifying for Medicaid. Understanding when you might qualify gives you some flexibility if your situation changes mid-year. Even if your current plan "works well," it's always worth reviewing other potential plans when you qualify for one of these periods.

Compare plans the right way

One of the most common mistakes is focusing too heavily on the monthly premium. A lower premium might look appealing, but total costs often tell a different story.

When comparing plans, consider:

• Total annual cost (premium + expected out-of-pocket)
• Provider network compatibility
• Drug coverage and restrictions

A slightly higher premium could end up costing less overall, depending on how you use care.

Build a short list before enrollment begins

Instead of starting from scratch in October, narrow your options now. Create a shortlist of 2-3 plans that include your preferred doctor, cover your medications at a reasonable price, and fit your expected health care usage.

When Open Enrollment begins, you'll already have a strong starting point instead of sorting through dozens of options under pressure.

Gather key documents ahead of time

Enrollment decisions go faster when everything is in one place. Set aside your current medication list, your preferred doctors and specialists, and recent medical bills. Having these on hand can help you compare plans based on what you need specifically, not on premiums alone.

A key change in 2026 to Medicare Part D was the $2,100 cap. For 2027, the list of drugs with federal negotiated prices is expanding to include 15 more medications, including certain popular treatments for diabetes and weight loss. Because these prices change how plans are structured, your "tried and true" plan from this year might not be the most cost-effective one next year.

Watch out for these common timing mistakes

Waiting until the last minute tends to create avoidable problems. Some of the most common missteps include:

• Choosing a plan without checking drug coverage
• Overlooking network restrictions
• Missing deadlines
• Not checking copays, coinsurance, and prior authorization rules

These aren't small things. They impact your access to care and your budget for the entire year.

Use these months to prepare

Most people think of Medicare decisions as a fall task. In reality, the groundwork happens months earlier.

Use this window to review, track, and prepare. This gives you real data and time to help you think clearly instead of rushing. That alone can help you make better decisions during Open Enrollment.

Bottom line

Medicare Annual Enrollment may still be months away, but the decisions that matter most often start now. Taking time to review your current plan, track your health care use, and understand potential changes could help you make smarter, more confident choices later. Rushing often leads to missed details, while a little preparation may help you avoid costly surprises.

One often-overlooked step is to check how your plan handles referrals, prior authorizations, and out-of-network care, especially if your health needs change unexpectedly. These rules can impact access and costs in ways that aren't obvious upfront. Picking a plan with rules that fit your needs can lead to a more stress-free retirement.
