How Do You Compare Medicare Plan Coverage?
Last Updated: October 31, 2026
Quick Summary
To compare Medicare plan coverage, put every plan into one worksheet and score them 1 to 5 on five factors: premium, deductible and copays, drug formulary placement, provider network status, and out-of-pocket maximum. Add the scores, but a plan that scores poorly on drugs or doctors rarely recovers.
Original Medicare lets you see any Medicare-accepting provider nationwide, while Medicare Advantage uses a plan network with referrals common.
Run a healthy-year and a heavy-year scenario through each plan so the comparison is apples to apples.
List every prescription by exact name, dose, and frequency, then check each plan's formulary tier by tier.
Verify each provider against the exact plan name and plan year, not the carrier's general network.
Original Medicare has no out-of-pocket cap on Part A and Part B cost-sharing, which is why many people pair it with Medigap.

Start With a Side-by-Side Comparison Worksheet
The fastest way to compare Medicare plan coverage is to put every plan into one worksheet and score them against the same five factors. A worksheet helps prevent that kind of surprise.
Medicare plan coverage is the set of services, drugs, and providers a specific plan will pay for, and it varies by plan type, carrier, and county. Two plans with identical premiums can cover very different things.
The Five Factors Every Worksheet Needs
Give each plan a score of 1 to 5 on every line:
Monthly premium and any late-enrollment penalty attached to it
Deductible and copays for the services you actually use
Drug formulary placement for each of your prescriptions
Add the scores. The highest total is not automatically the winner, but a plan that scores poorly on drugs or doctors rarely recovers.
Where to Find Current Plan Details
Use the official Medicare Plan Compare tool to pull every plan in your ZIP code, then open each plan's Summary of Benefits. Check the plan year printed on the document. Carriers also publish comparison pages, such as Humana's Medicare Advantage comparison resource, but treat carrier material as a starting point and confirm details in the official listing.
Compare Medicare Advantage Plans Against Original Medicare
The core trade-off is simple: Original Medicare lets you see any provider nationwide who accepts Medicare, while Medicare Advantage trades that freedom for extras and a network. Original Medicare is government-run Part A and Part B. Medicare Advantage is Part C, a private plan that delivers your Part A and Part B benefits and usually adds drug coverage.
HMO vs. PPO: What the Letters Mean for Your Access
An HMO generally requires you to stay in-network and often requires a referral to see a specialist. A PPO usually lets you see out-of-network providers at a higher cost. If you split time between two states, that difference matters more than a small premium gap.
Medicare Supplement, or Medigap, is a separate product that pairs with Original Medicare and helps with copays and coinsurance. For a deeper walkthrough of how these plan families differ, read our guide on Medicare Supplement vs Medicare Advantage, and if you are still weighing the two core paths, see how to choose between Original Medicare and Medicare Advantage.
Factor | Original Medicare | Medicare Advantage |
Provider access | Any Medicare-accepting provider | Plan network; referrals common |
Drug coverage | Add Part D separately | Usually bundled |
Extra benefits | Limited | Dental, vision, fitness vary by plan |
Out-of-pocket cap | None on Part A/B | Annual maximum applies |
Break Down Medicare Plan Costs Beyond the Premium
A low premium is the least reliable signal of total cost. The number that matters is what you would actually spend across a full plan year, and that number is built from five moving parts: the monthly premium, the deductible, the copay or coinsurance for each service, the drug costs at your pharmacy, and the annual out-of-pocket maximum that caps your exposure.
The Five Cost Components, In Order
Monthly premium. Multiply by 12. Add any Part B late-enrollment penalty if it applies to you, and any Part D late-enrollment penalty if the plan includes drug coverage.
Deductible. The amount you pay before the plan begins sharing costs. Deductibles vary by plan and by service category, a plan may have one deductible for medical services and a separate one for drugs.
Copays and coinsurance. A copay is a flat dollar amount per visit or fill; coinsurance is a percentage of the allowed charge. A 20% coinsurance on an expensive service can dwarf a $0 copay on a cheap one.
Drug costs. Tier placement, pharmacy type, and whether the plan uses a deductible for drugs all change the annual total. Two plans with the same premium can differ by hundreds of dollars a year on the same prescription list.
Out-of-pocket maximum. The ceiling on what you pay for covered in-network services in a plan year. Once you hit it, the plan pays 100% of covered in-network costs for the rest of the year. Original Medicare has no such cap on Part A and Part B cost-sharing, which is why many people pair it with a Medigap policy.
Build Two Scenarios Before You Enroll
Run every plan through the same two care-use scenarios so the comparison is apples to apples.
Scenario A, a healthy year. Assume 12 months of premiums, two primary care visits, one specialist visit, a routine screening, and a single generic prescription filled monthly at a standard (non-preferred) pharmacy. Add the deductible if the plan applies one to any of those services.
Scenario B, a heavy year. Assume 12 months of premiums, an inpatient hospital stay, six specialist visits, one imaging procedure, and a tier-three brand drug filled monthly. Push the math until you either hit the out-of-pocket maximum or exhaust the services listed.
The gap between Scenario A and Scenario B is your financial risk under that plan. A plan that looks cheap in a healthy year but spikes hard in a heavy year is telling you something about its cost-sharing structure.
Pro Tip Use the plan's Summary of Benefits for the exact copay and coinsurance amounts, and the Evidence of Coverage for the rules attached to each service. The Summary is a snapshot; the Evidence of Coverage is the contract.
Where the Numbers Come From
Every plan sold through Medicare must publish a Summary of Benefits and an Evidence of Coverage for the plan year. Pull both from the official Medicare Plan Compare tool listing for your ZIP code, and confirm the plan year printed on the document matches the year you are enrolling for.
Our breakdown of the Medicare Advantage out-of-pocket maximum versus Original Medicare explains why that ceiling is the number to watch when you compare a heavy-year scenario across plan types.
Check Medicare Prescription Drug Coverage by Medication
List every prescription by exact name, dose, and frequency, then check each plan's formulary tier by tier. A drug on tier two in one plan can sit on tier four in another, and the annual difference is often larger than the premium gap.
Watch out: formularies change between plan years, so a drug covered this year may move tiers or require prior authorization next year. Recheck every fall.
Verify Provider and Facility Networks Before You Enroll
A plan's network is the list of doctors, specialists, hospitals, and pharmacies it will pay at in-network rates. Carrier directories go stale, and a provider who accepted a plan last year may have dropped it this year. Verify every provider you rely on against the specific plan name and plan year, not the carrier's general network, before you enroll.
A Repeatable Verification Process
Work through this checklist for each plan you are seriously considering:
List every provider by full name and location. Include your primary care doctor, each specialist, your preferred hospital, any surgery center or imaging facility you use, and your preferred pharmacy. Do not skip the pharmacy, preferred versus standard pharmacy status can change your drug copay substantially.
Check the carrier's online directory first. Search by the exact plan name, not the carrier name. Note the date the directory was last updated; if it is more than a few months old, treat the result as unconfirmed.
Call the provider's office and ask a specific question. Ask: "Are you in-network for [exact plan name] for the [plan year] plan year?" A general "we take that insurance" is not the same answer. Ask about the specific plan, and ask whether referrals are required to see that provider.
Call the plan's member services line and confirm the same answer. If the directory and the provider's office disagree, ask the plan to confirm in writing or note the call reference number.
Document who you spoke with and when. Record the name, date, and answer for each provider. If a claim is later denied on network grounds, this record is your starting point for an appeal.
Facilities, Pharmacies, and Service Areas
Hospitals and facilities are often the weakest link in a network check. A plan may list your doctor as in-network while the hospital where that doctor admits patients is out-of-network, or vice versa.
Pharmacies work the same way. Most plans have a preferred pharmacy tier with lower cost-sharing and a standard tier with higher cost-sharing. Confirm your pharmacy's tier for each plan, and check whether the plan's service area covers every county where you spend significant time.
Watch Out Networks can change mid-year. A provider may leave a network, and a plan may change its pharmacy tiers, with notice that is easy to miss. Recheck your providers and pharmacy each fall during open enrollment, and again if you receive a network-change notice from the plan.
If you travel or spend part of the year elsewhere, network access deserves extra weight. Our guide to the best Medicare plan for people who travel covers how plan types behave away from home, including out-of-network rules and service-area limits.
Review Coverage Rules and Access Restrictions
Coverage rules decide whether a covered service is actually usable. Prior authorization, step therapy, referral requirements, and service-area limits all sit between you and care. Read the plan's Evidence of Coverage for the rules attached to your most likely services, not just the list of benefits. A plan that covers a procedure but requires a referral you cannot easily get is not real coverage.

Frequently Asked Questions
How do I compare Medicare plans?
Start by listing your doctors, prescriptions, and preferred pharmacies. Then use a Medicare plan comparison worksheet to line up premiums, deductibles, copayments, and out-of-pocket maximums side by side. Check each plan's provider network and drug formulary before enrolling. The Medicare Plan Compare tool on Medicare.gov lets you enter your drugs and pharmacies to see estimated costs for available plans. An independent agent can help you interpret the results and verify current-year details.
What should I compare when choosing a Medicare plan?
Focus on five factors: total annual cost (not just the premium), provider network, prescription drug coverage, coverage rules like prior authorization, and plan quality ratings. Medicare plan costs include deductibles, copayments, and coinsurance that can add up quickly. Also confirm whether your specialists are in-network and whether your medications are on the formulary. A worksheet that captures all five factors prevents surprises after enrollment.
How do I find out whether my doctors are covered by a Medicare plan?
Check the plan's online provider directory or call the plan directly and confirm that each doctor is in-network for the current year. Consumer Reports recommends verifying this before enrolling in a Medicare Advantage plan. Ask specifically about your primary care doctor and any specialists you see regularly. Network participation can change, so recheck each year during open enrollment. An independent agency can help you cross-reference several plans at once.
How can I compare Medicare Advantage and Original Medicare?
Original Medicare (Parts A and B) lets you see any provider who accepts Medicare nationwide, but you may need a Medigap policy and a Part D plan for drug coverage. Medicare Advantage plans often bundle drug coverage and may include extra benefits, but they use provider networks and prior authorization rules. Compare total costs, doctor access, and drug coverage side by side. The right choice depends on your health needs and tolerance for network restrictions.
How do I compare prescription drug coverage in Medicare plans?
List each medication, dose, and frequency, then check each plan's formulary to confirm your drugs are covered at the tier you expect. Compare copayments for a 30-day and 90-day supply, and confirm your preferred pharmacy is in-network. Medicare prescription drug coverage varies widely between plans, so the lowest premium may not be the lowest total cost. Use the Medicare Plan Compare tool to enter your drugs and see estimated annual costs.
The plans available in your area will change, and the formulary that fits you this year may not fit next year. Newport Benefits tracks those regulatory changes and works from all major carriers, so the comparison reflects your actual doctors and prescriptions rather than a generic list. Get started with Newport Benefits and compare your options with a worksheet built around your health needs.
