Quick Answer

Medicare's Plan Finder tool (available at medicare.gov) is a free, legitimate starting point for comparing Part D drug plans and Medicare Advantage options in your zip code. It shows premiums, deductibles, and formulary data — but it cannot tell you whether a plan's network includes your doctors, how a plan actually performs in customer service, or which coverage type makes more sense for your health situation. Use it as a first look, not a final decision.

Key Takeaways

• Medicare Plan Finder shows cost estimates for Part D and Medicare Advantage plans, but network and quality details require extra digging.
• The tool does not compare Medicare Supplement (Medigap) plans — a significant gap for many people considering that route.
• Starting in 2025, Part D out-of-pocket costs are capped at $2,000/year under the Inflation Reduction Act — the tool reflects this, but it cannot predict your actual spending.
• The 2026 Medicare Advantage out-of-pocket maximum cap is $9,350 for in-network services (CMS, 2025) — plans may set their limits lower, and the tool shows these variations.
• A free Medicare review with a licensed advisor can catch what the tool misses, especially around Medicare Advantage vs. Supplement decisions.

What Medicare Plan Finder Actually Does {#what-plan-finder-does}

Medicare Plan Finder is a free CMS-run tool at medicare.gov. You enter your zip code, the drugs you take (with dosages), and your preferred pharmacies. The tool then returns a list of available Part D standalone plans and Medicare Advantage plans with drug coverage (MAPD), sorted by estimated annual cost.

It pulls real data from CMS plan filings — so the premium figures, deductibles, and formulary tier placements you see are accurate as of the plan year. The 2026 standard Part B premium is $185/month and the Part B deductible is $257 (CMS, November 2025), and those figures feed into the overall cost picture the tool displays.

What it is not: a personalized health analysis, a network verification system, or a replacement for professional guidance.

Where the Tool Genuinely Helps {#where-it-helps}

For specific, data-driven tasks, Plan Finder is actually quite good.

Drug cost comparisons. If you take several brand-name or specialty medications, entering them into Plan Finder can reveal significant cost differences between Part D plans. With covered insulin now capped at $35/month under Medicare Part D and a $2,000 annual out-of-pocket ceiling in place since 2025 (Inflation Reduction Act), the tool can show you how those caps apply across different plans.

Side-by-side plan premiums. You can filter plans by premium, deductible, or star rating — giving you a quick apples-to-apples snapshot of what's available in your zip code.

Star ratings. CMS assigns 1-5 star quality ratings to Medicare Advantage and Part D plans. Plan Finder displays these, and they're worth paying attention to. A plan rated 3.5 stars or lower may signal recurring complaints about claim processing or customer service.

For a deeper look at 2026 Medicare costs and how they affect your decision, it helps to understand the full picture before relying solely on the tool's estimates.

What Plan Finder Cannot Tell You {#what-it-misses}

This is where people get into trouble. The tool has some meaningful blind spots.

It doesn't verify your doctors are in-network. A Medicare Advantage plan might look affordable on Plan Finder, but if your cardiologist or orthopedic specialist isn't in the plan's network, your real costs could be dramatically higher. You have to check network status separately — directly with the plan or your provider's office.

It doesn't show Medigap plans at all. If you're weighing Medicare Advantage vs. a Medicare Supplement (Medigap) plan, Plan Finder only shows you one side of that equation. Medigap plans — which pair with Original Medicare and can significantly reduce your out-of-pocket exposure — aren't listed in the tool. That's a big gap for anyone early in the decision process.

Cost estimates are based on averages. The tool estimates your drug costs using typical usage patterns and preferred pharmacy pricing. If you use a mail-order pharmacy, a specialty pharmacy, or fill medications inconsistently, the estimates may not reflect your actual situation.

It can't flag prior authorization requirements clearly. Many Medicare Advantage plans require prior authorization for certain procedures, specialist visits, or high-cost drugs. The tool doesn't surface this in a way that's easy to assess without reading plan documents carefully.

North Carolina-Specific Considerations {#north-carolina-considerations}

If you're doing a Medicare plan review in North Carolina, a few things are worth knowing before you rely heavily on Plan Finder.

North Carolina has a mix of urban and rural counties, and Medicare Advantage plan availability can vary sharply depending on where you live. In metro areas like Charlotte, Raleigh, or Asheville, you may see a dozen or more Medicare Advantage plans available. In more rural counties, options may be limited to one or two — or none. Plan Finder will show you what's available by zip code, but it won't explain why choices are limited or what that means for your care access.

North Carolina also has a well-established Medigap market, and for many North Carolina Medicare enrollees — particularly those who travel frequently or see specialists outside a single metro area — a Supplement plan paired with a standalone Part D drug plan may offer more flexibility than a Medicare Advantage HMO. Plan Finder cannot help you weigh that tradeoff. That's a conversation worth having with a licensed Medicare advisor who knows the North Carolina market.

For reference on broader enrollment trends, national Medicare Advantage enrollment sits at roughly 54% of all Medicare beneficiaries (CMS, 2024) — meaning nearly half of people on Medicare are still in Original Medicare, often paired with a Medigap plan.

How to Use Plan Finder Without Getting Misled {#how-to-use-it-well}

Here's a practical approach:

1. Enter your actual drugs and dosages. Vague entries produce inaccurate cost estimates. 2. Filter by your preferred pharmacy. Costs vary meaningfully between retail, mail-order, and preferred pharmacy networks. 3. Look at star ratings, not just premiums. A $0-premium plan with 2.5 stars may cost you more in hassle and denied claims than a $40-premium plan rated 4.5 stars. 4. Use it alongside our plan comparison tool for a broader view of your options. 5. Don't skip the plan documents. The Summary of Benefits for any plan you're seriously considering will tell you about prior authorizations, referral requirements, and service area restrictions.

When to Talk to a Licensed Advisor Instead {#when-to-talk-to-an-advisor}

Plan Finder is worth using — but it works best as a starting point, not a finishing line. Consider talking to a licensed Medicare advisor if:

• You're choosing Medicare for the first time and unsure whether Advantage or Supplement fits your situation
• You've had coverage changes, a new diagnosis, or a significant change in medications
• You're in a rural North Carolina county with limited plan options and aren't sure what to do
• You want someone to verify that your specific doctors and hospitals are actually in-network before you enroll

A licensed advisor can look at your full picture — health needs, budget, providers, travel habits — in a way that a database tool simply cannot. You can also browse the Medicare Advantage guide, Medigap guide, and enrollment periods guide to build your baseline knowledge before any conversation.

Frequently Asked Questions {#frequently-asked-questions}

Q: Is Medicare's Plan Finder tool official and accurate? A: Yes — it's run by CMS and pulls directly from official plan filings, so premium and formulary data is accurate for the plan year. That said, cost estimates are based on usage averages, and the tool cannot verify network details or predict your individual spending.

Q: Can I use Plan Finder to compare Medigap plans? A: No. Medicare Plan Finder only covers Medicare Advantage and Part D drug plans. For Medigap comparisons, you'll need to work with a licensed Medicare advisor or use a separate resource like our Medicare Supplement guide.

Q: How often should I use Plan Finder to review my plan? A: Once a year, during the Annual Enrollment Period (October 15 - December 7), is the right time to check. Plans can change their premiums, formularies, and networks each year, so a plan that worked well in 2025 may look very different in 2026.

Q: Does Plan Finder show the $2,000 Part D out-of-pocket cap? A: Yes. Since the Inflation Reduction Act cap took effect in 2025, Plan Finder reflects the $2,000 annual limit in its cost estimates. However, your actual spending depends on your specific drugs, dosages, and the plan's formulary tier placement.

The Bottom Line

Medicare's Plan Finder is a useful, free tool — and you should probably use it. But it's a starting point, not a complete answer. It misses Medigap entirely, can't verify your doctors are in-network, and can't help you decide which type of coverage suits your health and lifestyle. If you're doing a Medicare plan review in North Carolina or anywhere else and want a second set of eyes, I'm happy to walk through your options with you. Schedule your free Medicare review today — no pressure, no sales pitch, just straight answers.
