The best Medicare plan is the one that covers your doctors and prescriptions at a total cost you can manage within your retirement budget. There is no single right answer that works for everyone, because the right plan depends entirely on your specific providers, medications, health history, and financial situation. A simple process helps you move from overwhelmed to confident: list your needs, compare plans on the same criteria, and confirm the details before you enroll.
Key Takeaways
- Start with your doctors, medications, and expected care needs before looking at any plan
- Compare total annual cost including premiums, deductibles, and expected cost-sharing, not monthly premium alone
- Confirm provider participation and drug formulary coverage before finalizing any enrollment decision
- Build an annual review habit because plan details change every year even if you do not
Step 1: List Your Healthcare Priorities
Before you open a plan brochure or visit Medicare.gov, spend time documenting what you actually need from a healthcare plan. This information is the foundation of every comparison you will make, and having it organized before you start saves significant time and prevents costly oversights.
Doctors You Want to Keep
Write down the name, practice name, and location of every physician you see or expect to see in retirement. This includes your primary care physician, any specialists you see regularly for ongoing conditions, and any specialists you may need in the near future for planned procedures or referrals. Include any hospitals or surgical centers you prefer or are likely to use.
For each provider, note whether you have a long-standing relationship that matters to you or whether you are open to finding new providers if a plan requires it. This distinction helps you decide how important broad network access is relative to cost considerations. For providers you are not willing to change, confirm their Medicare participation status and, for any Medicare Advantage plan you consider, their in-network status specifically.
Medications You Take
Compile a complete list of every prescription medication you take regularly or periodically. For each drug, record the name, the dosage, and how many times per month or year you fill it. Include any specialty medications, injectables, or medications that are particularly expensive, as these tend to have the most variation in coverage and cost across plans.
This list is the input you will use in Medicare’s Plan Finder tool at Medicare.gov, which allows you to enter your medications and compare how different Part D or Medicare Advantage plans cover them, at what cost tier, and at your preferred pharmacy. Without this list, any drug coverage comparison is incomplete.
Expected Services
Think through the healthcare services you expect to use in the coming year beyond routine primary care. Ongoing specialist visits for managed conditions, planned imaging or lab work, physical therapy or other rehabilitation services, mental health services, outpatient procedures, and any planned surgeries or interventional care all represent cost-sharing events that vary between plans.
Estimating your expected utilization as realistically as possible allows you to model total annual cost under different plan options rather than simply comparing premiums. A plan that looks inexpensive monthly may produce significantly higher total costs for someone with frequent specialist visits or planned procedures.
Step 2: Estimate Your Total Annual Cost
Monthly premium is the number most prominently displayed in plan comparisons, but it is often the least useful single figure for making a good decision. Total annual cost, which includes premiums, deductibles, copays, coinsurance, and drug costs at your expected utilization level, is the number that actually matters.
Premiums
Start with the monthly premium for each plan option you are seriously considering. For Medicare Advantage, this is the plan’s monthly premium in addition to the Part B premium you pay regardless. For Original Medicare with Medigap, this includes the Part B premium, the Medigap plan premium, and a separate Part D plan premium. Multiply the total monthly premium across all components by twelve to get your annual premium cost.
Higher-income beneficiaries also pay IRMAA surcharges on top of the standard Part B and Part D premiums. If your modified adjusted gross income from two years ago exceeded the IRMAA threshold, add those surcharges to your premium calculation. Your advisor and CPA can help you anticipate whether significant income events in the current or prior year may trigger IRMAA in future years.
Deductibles and Copays
Each plan has its own cost-sharing structure. For Medicare Advantage plans, review the annual deductible if applicable, the copay for primary care visits, the copay or coinsurance for specialist visits, the cost structure for outpatient procedures and imaging, and the hospital cost-sharing for inpatient stays. For Original Medicare with Medigap, review which deductibles and cost-sharing the Medigap plan covers and which remain your responsibility.
Estimate your expected annual cost-sharing by multiplying the copay or coinsurance amounts by your expected frequency of use for each service type. A plan with a $50 specialist copay and twelve specialist visits per year carries $600 in specialist cost-sharing before any other expenses. That figure belongs in your annual cost estimate.
Out-of-Pocket Maximums
For Medicare Advantage plans, note the annual out-of-pocket maximum for in-network services. In 2026 the federal maximum is $9,250 for in-network services, though individual plans often set lower limits. This cap defines the worst-case scenario for medical cost-sharing in a given year, not including drug costs.
For Original Medicare without Medigap, there is no out-of-pocket maximum, which means a catastrophic health event could result in unlimited cost-sharing exposure. This is one of the primary reasons many beneficiaries on Original Medicare add Medigap coverage. For Original Medicare with a comprehensive Medigap plan, your cost-sharing exposure is minimal and largely predictable.
Step 3: Check Plan Rules That Can Surprise People
Even when the premium and estimated costs look good, plan rules can create friction and unexpected expense in practice. Understanding these rules before you enroll prevents unpleasant discoveries when you actually need care.
Network and Referrals
If you are considering a Medicare Advantage plan, confirm whether it is an HMO or a PPO structure. HMO plans typically require a primary care physician, require referrals to see specialists, and restrict coverage to in-network providers except for true emergencies. PPO plans allow more flexibility to see out-of-network providers, typically at higher cost-sharing.
For each plan you are seriously considering, confirm that your priority doctors and hospitals are currently in-network. Do not rely on a network directory from the prior year. Providers can leave networks, and the network that applied in 2025 may not be identical to the one that applies in 2026. Confirm current participation directly with the plan or by calling the provider’s billing office.
Prior Authorizations
Prior authorization requirements mean the plan must approve certain services before they are covered. This is a routine feature of Medicare Advantage plans and is less common under Original Medicare. The types of services that require prior authorization vary by plan and can include specialist referrals, imaging studies, outpatient procedures, certain medications, and inpatient admissions.
Prior authorization does not prevent you from receiving care, but it can create delays, administrative burden, and in some cases denials that require appeal. If you have ongoing specialist care or planned procedures, ask specifically which services require prior authorization under any plan you are considering and how the appeals process works.
Out-of-Area Coverage and Travel
If you travel frequently, spend time in multiple states, or plan to relocate in retirement, understand how each plan handles care outside its primary service area. Most Medicare Advantage plans cover emergency and urgently needed care outside the plan’s service area, but routine care is generally limited to the in-network area. For a retiree spending six months per year in a different state, a plan anchored to a single service area may create significant coverage gaps for non-emergency care.
Original Medicare with Medigap covers care from any Medicare-accepting provider anywhere in the country, which provides complete domestic portability. Several Medigap plans also include coverage for emergency care outside the United States, which matters for retirees who travel internationally.
Step 4: Build a Yearly Review Habit
Medicare plans are not permanent. Premiums change, formularies change, networks change, and plan quality ratings change, all every year on January 1. A coverage decision that was optimal at enrollment may be suboptimal twelve months later if you have not reviewed it.
Annual Check-In
Each fall, between October 15 and December 7, Medicare’s Annual Open Enrollment Period gives you the opportunity to review your current coverage and make changes that take effect January 1. Use this window every year, not only when something has obviously changed.
The review should confirm that your current medications are still covered at the same tiers and at the same pharmacy. It should confirm that your doctors and hospitals are still in-network if you are in a Medicare Advantage plan. It should compare whether better options now exist in your market given any changes to your health, spending, or coverage needs. Even in years when you decide to keep your current plan, completing the review confirms that the decision was deliberate rather than a default.
Your plan will send you an Annual Notice of Change before October 15 each year summarizing what is changing in your current coverage for the coming year. Read this notice carefully. Changes to formulary tiers, cost-sharing, or network composition are disclosed here and can significantly affect your total annual cost even if the premium change is modest.
What Triggers a Mid-Year Review
Several events during the year may qualify you for a Special Enrollment Period and warrant a mid-year review of your coverage. Moving to a new address outside your current plan’s service area, losing creditable coverage from another source, experiencing certain changes in your health situation, and in some cases qualifying for programs like Extra Help for drug coverage can all trigger a window to make coverage changes outside the standard annual enrollment periods.
Even without a qualifying event, a mid-year review with your advisor is worth scheduling if you experience a significant change in your health status, are diagnosed with a new condition requiring ongoing specialist care, add new expensive medications to your regimen, or are anticipating a major planned procedure. These changes affect your total annual cost under the current plan and may indicate that a different plan would serve you better at the next Annual Open Enrollment Period.
FAQs
A plan is a good fit when it covers your specific doctors and hospitals, includes your medications on its formulary at a reasonable cost tier, and produces a total annual cost including premiums and expected cost-sharing that fits within your retirement budget. Star ratings published by Medicare reflect quality and performance measures for Medicare Advantage and Part D plans and are a useful additional data point when comparing plans of similar cost. A plan rated four stars or higher generally indicates strong performance on member experience, care quality, and customer service measures. But star rating alone does not determine fit. A highly rated plan that does not cover your providers or drugs is not a good fit for your situation.
Ask whether they represent all available plans in your area or only specific carriers, since an advisor who represents only a subset of carriers cannot give you a complete market comparison. Ask how they are compensated, as Medicare insurance brokers are typically compensated by the insurance companies, but independent brokers with broad carrier access generally work in your interest regardless of which plan you choose. Ask them to show you the total annual cost comparison for each option at your expected utilization level, not just the premium. Ask what happens if a plan's network changes next year and your doctors are no longer in-network. And ask how they will support you if you need to appeal a coverage denial or need help understanding a claim.
Original Medicare does not cover routine dental, vision, or hearing care. Some Medicare Advantage plans include dental, vision, and hearing benefits, which is one of the supplemental appeal of those plans. However, the scope and quality of these benefits vary significantly between plans and often have annual limits, waiting periods, or restrictions that make them less comprehensive than they appear in plan marketing materials. If you anticipate significant dental or vision expenses, review the specific coverage details carefully rather than treating the presence of these benefits as equivalent to comprehensive coverage. Standalone dental and vision insurance plans are also available for purchase separately if you are on Original Medicare with Medigap and need these services covered.
Ongoing specialist relationships are one of the most important factors in the Medicare coverage decision. If you have a specialist you see regularly for a managed condition and that specialist is not in a Medicare Advantage plan's network, you face a choice between keeping the specialist at higher out-of-network cost or finding a new in-network specialist. For many retirees with established specialist relationships, this is a significant practical reason to favor Original Medicare with Medigap, which allows you to see any Medicare-accepting specialist anywhere without network restrictions or referral requirements. Before enrolling in any Medicare Advantage plan, confirm the current in-network status of every specialist you see regularly.
Use Medicare's Plan Finder tool at Medicare.gov, which allows you to enter your complete medication list and compare how different plans cover each drug, at what cost tier, and at your preferred pharmacy. The tool calculates your estimated annual drug costs under each plan, which allows you to compare plans on total drug cost rather than premium alone. When reviewing results, pay particular attention to any drugs placed in specialty tiers, as these typically carry the highest cost-sharing. Also note whether any of your medications require prior authorization or step therapy under a given plan, as these requirements can delay access or require you to try less effective alternatives first.
Yes. Medicare IRMAA surcharges add to the standard Part B and Part D premiums for beneficiaries whose modified adjusted gross income exceeds certain thresholds. The surcharges are based on income from two years prior and are recalculated annually. In 2026, the IRMAA threshold begins at $109,000 for single filers and $218,000 for joint filers. A year with elevated income from a home sale, large Roth conversion, or significant IRA withdrawal can produce higher Medicare premiums two years later even if your ongoing income is lower. Your financial advisor and CPA can help you model and anticipate IRMAA exposure as part of your broader retirement income and tax planning.
Every year without exception. Use the Annual Open Enrollment Period from October 15 to December 7 to confirm that your current coverage still fits your needs for the coming year. Read the Annual Notice of Change your plan sends before October 15 to understand what is changing. If everything looks consistent with your needs, staying in your current plan is a deliberate decision rather than an oversight. Also review mid-year if your health situation changes significantly, if you add new expensive medications, or if a qualifying life event gives you access to a Special Enrollment Period.
Choosing a plan based on premium alone without comparing total annual cost at their expected utilization level is the most common mistake, and often the most expensive one. Failing to verify that specific doctors and hospitals are currently in-network before enrolling in a Medicare Advantage plan is a close second, resulting in unexpected out-of-network charges or the need to find new providers after enrollment. Missing the Medigap guaranteed-acceptance enrollment window at 65 and assuming switching later will be easy is a mistake that can limit options for the rest of retirement, since medical underwriting in most states can result in denial or higher premiums. And not reviewing coverage annually during the open enrollment period means plan changes that affect your drug costs, network, or premium go unnoticed until they appear on a bill.
