Learn to Compare Medicare Plans 2027: Coverage and Medicare Advantage
To compare Medicare plans 2027 well, start with the decisions that shape both your care and your budget: how you want to receive medical services, which doctors and hospitals you want to use, and how much uncertainty you can comfortably carry in out-of-pocket costs. Medicare is not one uniform type of insurance.
Original Medicare includes Part A hospital coverage and Part B medical coverage, and many people pair it with a standalone Part D prescription drug plan and, where available, a Medicare supplement policy. A Medigap plan can help pay certain deductibles and coinsurance, while leaving you free to see providers that accept Medicare nationwide.
Medicare Advantage plans are a different route. An Advantage plan bundles Parts A and B through a private insurer and commonly includes drug coverage, plus extras such as dental, vision, hearing, fitness, or transportation benefits. In exchange, these plans generally use provider networks and plan rules, including referrals or prior authorization for some services.
The lowest monthly premium is not always the lowest-cost choice. Compare copays for specialist visits, hospital stays, imaging, and outpatient procedures; the annual maximum for covered in-network spending; prescription formularies; and the cost of using care outside the network.
As you compare types of coverage, make a list of your current physicians, preferred pharmacies, regular prescriptions, and anticipated treatment needs. Then check each plan’s provider directory and drug plans directly rather than relying on a general summary.
Review premiums alongside deductibles, copays, coinsurance, and the maximum you could pay from your own pocket in a difficult health year. Plan benefits and networks can change annually, so a plan that suited you last year deserves a fresh look for 2027. The right choice is the one that gives you dependable access to care with Medicare costs you understand before you enroll.

Medicare Comparison Checklist
- Choose between Original Medicare with supplements and Part D, or Medicare Advantage with bundled coverage and network rules.
- List your doctors, hospitals, pharmacies, prescriptions, and expected treatments before reviewing specific plan options.
- Confirm every preferred provider participates by checking plan directories and contacting offices directly.
- Compare prescription formularies, pharmacy networks, coverage restrictions, and your expected medication costs.
- Review premiums, deductibles, specialist copays, hospital charges, imaging costs, and outpatient procedure coinsurance.
- Check each plan’s annual out-of-pocket maximum, especially if a serious illness or major treatment is possible.
- Reassess coverage annually, since provider networks, drug coverage, benefits, and costs may change for 2027.
Medigap, Providers and Prescription Coverage: Build Your Local Shortlist
A strong local Medicare shortlist starts by separating the choices that are often bundled together in conversation but work very differently in practice. Original Medicare lets you see any doctor or hospital that accepts Medicare, while a Medigap policy is supplemental insurance designed to help with certain out-of-pocket costs left by Original Medicare.
Medigap plans generally do not use a provider network, so the key question is whether your preferred providers accept Medicare and are taking new patients, not whether they belong to a particular carrier’s network. That distinction can be especially valuable for a senior who sees specialists across county lines or wants broad flexibility for care and services.
Prescription drug coverage is another separate decision. Original Medicare does not include most retail prescriptions, so you may need a standalone Part D plan; Medicare Advantage plans often include drug coverage, but their provider network, pharmacy rules and referral requirements deserve close review.
Start with the doctors, hospitals, pharmacies and medications you use now. Then enter your ZIP code in Medicare’s plan finder at Medicare.gov to find plans available where you live, such as Montana, compare estimated drug costs, and confirm which pharmacies are preferred.
Do not rely on a general list alone: formularies can place the same medication on different cost tiers, and plans may require prior authorization or step therapy. For each Medicare plan under consideration, call the provider office directly and ask whether it accepts the exact plan and product name for the coming year.
Keep notes on monthly premiums, deductibles, copays, maximum out-of-pocket limits, drug restrictions and travel needs. A local independent agent, State Health Insurance Assistance Program, or trusted counselor can help explain the tradeoffs, but use official plan documents to verify details.
Make this comparison part of your annual review, since premiums, formularies, participating providers and plan benefits can change. The goal is not simply to find the lowest advertised premium; it is to select a program that fits your doctors, prescriptions, budget and day-to-day access to care.
Build Your Medicare Shortlist
- List current doctors, specialists, hospitals, pharmacies, and prescriptions before comparing coverage options.
- Confirm preferred providers accept Medicare and are accepting new patients, especially when considering Original Medicare with Medigap.
- Use Medicare.gov’s plan finder with your ZIP code to identify available Part D or Medicare Advantage plans.
- Compare each medication’s formulary tier, pharmacy pricing, prior authorization, step therapy, and quantity limits.
- Call provider offices to verify they accept the exact plan and product name for the upcoming year.
- Track premiums, deductibles, copays, maximum out-of-pocket limits, travel coverage, and referral requirements.
- Review choices annually, since provider participation, drug formularies, premiums, and benefits can change.
Open Enrollment and Your 2027 Medicare Plan: Review Before You Enroll
Medicare’s Annual Enrollment Period, often called open enrollment or AEP, is your principal opportunity to reassess whether your current coverage still fits your health, prescriptions and budget for 2027. The enrollment period runs from October 15 through December 7 each year, with changes taking effect January 1.
It is not simply a time to shop for a new Medicare Advantage plan; it is also the moment to confirm that staying put remains the right decision. Plans can change from one year to the next, sometimes in ways that are easy to miss. A familiar doctor may no longer be in a plan network.
A prescription drug may move to a different formulary tier, require prior authorization or carry a higher copay. Monthly premiums, deductibles, dental allowances, over-the-counter benefits and maximum out-of-pocket limits can all shift.
Your own circumstances may have changed as well: a new diagnosis, more frequent specialist visits, a move, or a medication added during the year can alter what represents good value. Start with the Annual Notice of Change and Evidence of Coverage materials your insurer sends in the fall. Read beyond the headline premium.
Compare the total cost of the care you realistically expect to use, including pharmacy costs, specialist copays and hospital coverage. Confirm that your preferred physicians, hospitals and pharmacies participate for 2027 not just that they participated this year.
If you are considering Medicare Advantage, look closely at referral rules, prior authorization requirements and the plan’s out-of-network protections, particularly if you travel or spend part of the year elsewhere. Annual enrollment also allows eligible beneficiaries to move between Medicare Advantage and Original Medicare, add or change a standalone Part D drug plan, or change from one Medicare Advantage plan to another.
The best option is personal, not promotional. A plan with generous extras may be less useful than one with stronger access to your doctors and medications. Take time to learn what each option covers before the December deadline; a deliberate review now can prevent costly surprises throughout the coming year.

Frequently asked questions
How do I compare Medicare plans for 2027?
Compare your total expected costs, not just the monthly premium.

Use Medicare.gov to review plans offered in your ZIP code, then confirm details directly with providers and insurers.
What is the difference between Original Medicare and Medicare Advantage?
Original Medicare includes Part A and Part B and allows you to use providers nationwide that accept Medicare. You can add a standalone Part D drug plan and may be able to buy Medigap coverage. Medicare Advantage is offered by private insurers, usually includes Parts A, B, and often Part D, but commonly uses provider networks and authorization rules.
Does Medicare Advantage include prescription drug coverage?
Many Medicare Advantage plans include Part D prescription drug coverage, but not every plan does. Review the plan formulary, medication tiers, pharmacy network, deductibles, copays, and restrictions such as prior authorization or step therapy before enrolling.
Can I keep my doctors with a Medicare Advantage plan?
It depends on whether your doctors and hospitals participate in the specific plan’s network. Provider directories can change, so contact each provider office and ask whether it accepts the exact Medicare Advantage plan and product name for 2027.
What does Medigap cover?
Medigap is supplemental insurance that can help pay certain deductibles, coinsurance, and other out-of-pocket expenses left by Original Medicare. It generally does not include retail prescription drug coverage, so many people also need a standalone Part D plan.
When is Medicare open enrollment for 2027 coverage?
Medicare Annual Enrollment runs from October 15 through December 7. Changes made during this period generally take effect on January 1, 2027. Review your Annual Notice of Change because premiums, benefits, drug coverage, and provider networks may change each year.
Why should I review my Medicare plan every year?
Your plan may change its premium, drug formulary, copays, provider network, benefits, and out-of-pocket limit. Your own health needs, prescriptions, providers, or travel plans may also change. An annual review helps ensure your 2027 coverage still fits your care and budget.
