Medicare.gov Plan Finder: How To Compare And Enroll In 2026

The Medicare.gov Plan Finder is the official tool from the Centers for Medicare & Medicaid Services (CMS) that lets you compare Medicare Advantage (Part C) and Part D prescription drug plans side by side. If you're trying to figure out what's available in your area for 2026, and what it'll actually cost, this is where you start.

But here's the thing: the tool gives you data, not guidance. You'll see dozens of plans with different premiums, deductibles, drug formularies, and provider networks. Making sense of all that on your own can feel overwhelming, especially if your health needs have changed or you're enrolling for the first time. That's exactly where our team at Golden Health and Life Agency steps in, we help clients cut through the noise by matching them with the right Medicare coverage from our network of over 300 carriers.

In this guide, we'll walk you through how to use the Plan Finder step by step, from entering your information to comparing plans and completing enrollment. Whether you're doing it yourself or want a second opinion before you commit, you'll have a clear picture of how the process works by the end.

What Medicare Plan Finder does and who can use it

The medicare.gov plan finder is a free, web-based comparison tool run by the Centers for Medicare & Medicaid Services. It pulls real-time plan data for your ZIP code and lets you see what Medicare Advantage and Part D drug plans are available, what they cost, and whether your specific prescriptions are covered. No login is required just to browse, which makes it easy to start comparing without committing to anything.

The Plan Finder updates its plan data annually for each coverage year, so the options you see now reflect 2026 plans.

What the tool shows you

Once you enter your location and add your medications, the Plan Finder displays a side-by-side comparison of available plans. For each plan, you can see the monthly premium, annual deductible, copays for specific drug tiers, and the estimated annual cost based on your drug list. It also shows CMS star ratings, which reflect plan quality and member satisfaction from prior years.

• Monthly premium and annual deductible

• Drug tier copays and coinsurance rates

• Estimated yearly drug costs based on your prescriptions

• CMS star ratings (1 to 5 stars)

• In-network pharmacy options

Who can use the Plan Finder

Anyone with Medicare Part A or Part B can use the Plan Finder to compare plans. That includes people who are newly eligible at 65, those under 65 who qualify due to a disability, and people with End-Stage Renal Disease. You can also use the tool on behalf of someone else, such as a spouse or parent, as long as you have their Medicare number and basic personal details on hand.

Current Medicare enrollees use the tool every fall during Open Enrollment (October 15 to December 7) to review whether their existing plan still fits their needs or whether switching makes financial sense for the coming year.

Step 1. Gather what you need before you compare

Before you open the medicare.gov plan finder, spending two minutes pulling together the right information will save you from stopping mid-search. The tool works best when you enter accurate data upfront, so your cost estimates and plan matches reflect your actual situation rather than guesswork.

Your Medicare and personal information

You'll need your Medicare Beneficiary Identifier (MBI), which is the 11-character alphanumeric code printed on your red, white, and blue Medicare card. Your ZIP code is also required, since plan availability varies significantly by location. If you're comparing plans on behalf of a spouse or parent, have their card ready instead of your own.

Your MBI replaces the old Social Security-based Medicare number; keep it secure and never share it publicly.

Your prescription drug list

The Plan Finder's cost estimates become much more accurate once you add your current medications. For each drug, collect the following details before you start:

• Drug name (brand and generic)

• Dosage (for example, 10 mg or 20 mg)

• Quantity per fill (for example, 30 or 90 tablets)

• Frequency (daily, weekly, as needed)

Having this list ready lets you compare true out-of-pocket drug costs across plans without interrupting the process to look up dosages or call your pharmacy.

Step 2. Use Plan Finder to price your drugs

Once you have your information ready, go to medicare.gov and open the Plan Finder tool. On the main search screen, enter your ZIP code and select whether you want to compare Part D drug plans only or Medicare Advantage plans that bundle drug coverage. The tool will prompt you to add your medications before it generates any cost estimates, so don't skip past that step.

How to enter your prescriptions

Adding your medications is what makes the medicare.gov plan finder produce numbers that actually apply to your situation. Use the drug search bar to look up each medication by name, then confirm the correct dosage and quantity. The tool saves your list for the session, so add all your drugs before you move to the results screen.

Here's a quick example of how to enter a common medication:

Field	Example Entry
Drug name	Atorvastatin (generic for Lipitor)
Dosage	20 mg
Quantity per fill	90 tablets
Frequency	Once daily

Once your full drug list is saved, the Plan Finder calculates your estimated annual out-of-pocket drug cost for each plan, which is the single most useful number to compare across your options.

Step 3. Compare Medicare Advantage and Part D

After your drug list is saved, the medicare.gov plan finder loads your results screen. Plans appear ranked by estimated annual cost, which combines your projected monthly premiums with out-of-pocket drug expenses. That number is your most useful starting point, but a few other factors deserve equal attention before you make a decision.

What to look at beyond the premium

The monthly premium grabs attention first, but total annual cost is what actually hits your wallet. Check each plan's deductible, copay structure for your drug tiers, and whether your preferred pharmacy qualifies as a preferred in-network location. A $0-premium plan can easily cost more overall if your medications land on Tier 4 or Tier 5.

• Star rating: Target 4 stars or higher for consistent plan quality

• Drug tier placement: Confirm your prescriptions aren't on a high-cost tier

• Preferred pharmacy: Verify your regular pharmacy, not just any in-network option

• Coverage gap protection: Check if the plan offers extra coverage beyond standard limits

Always compare the estimated annual total the Plan Finder calculates for your drug list, not just the monthly premium figure.

Choosing between Part D and Medicare Advantage

Standalone Part D plans pair with Original Medicare and give you the most flexibility in choosing doctors. Medicare Advantage plans bundle hospital, medical, and drug coverage into one plan, often adding dental or vision benefits. If you travel frequently or see specialists outside a fixed network, a standalone Part D plan combined with Original Medicare typically gives you broader access.

Step 4. Enroll, switch, and confirm coverage

Once you've picked a plan using the medicare.gov plan finder, you can enroll directly from the results screen without navigating to a separate site. Click "Enroll" next to your chosen plan, and the tool will either complete the enrollment through Medicare directly or redirect you to the plan's own website to finish the process.

How to complete enrollment online

The enrollment form asks for your Medicare Beneficiary Identifier, contact information, and the coverage start date you're requesting. Review every field before submitting, since errors can delay your start date or trigger a follow-up call from the plan. If you're switching from an existing Medicare Advantage or Part D plan, the new coverage automatically cancels your old plan when the new one takes effect.

You can also call 1-800-MEDICARE (1-800-633-4227) to enroll by phone if you prefer not to complete the process online.

Confirm your coverage is active

After submitting, expect a confirmation letter from your new plan within 10 business days. Do not assume your coverage is active until that letter arrives. Cross-check your plan ID card against the plan name and formulary you selected to make sure there are no discrepancies before your new coverage start date.

Next steps

The medicare.gov plan finder gives you a solid foundation for comparing 2026 plans, but the data only tells part of the story. Your actual costs depend on how your specific prescriptions, doctor visits, and preferred pharmacy interact with the plan you choose, and those details aren't always obvious on a results screen.

Working with an independent broker adds a layer of review that the tool alone can't provide. Golden Health and Life Agency compares options across more than 300 carriers, which means you get a broader picture than any single plan website offers. Before you lock in your choice, having an expert confirm you're not missing a better fit takes less time than you might expect.
