What this tool does
This tool helps you compare the three main Medicare coverage paths side by side: Original Medicare alone, Original Medicare combined with a Medigap supplement plan and a Part D drug plan, and Medicare Advantage (also called Part C). Each path has a very different structure for premiums, deductibles, out-of-pocket costs, and drug coverage.
You enter your age, state, health status, estimated number of doctor and specialist visits per year, how many prescription drugs you take, whether you travel frequently, and what matters most to you — lowest cost, best coverage, or a balance of both. The tool then uses current Medicare pricing data to estimate annual costs under each scenario and highlights which option best fits your situation.
Because Medicare premiums, Medigap rates, and Medicare Advantage plan costs change every year and vary significantly by state and county, this tool queries live AI-powered data rather than relying on hardcoded figures. The result is a personalized, up-to-date comparison rather than a generic chart.
Whether you are approaching your Initial Enrollment Period at age 65 or re-evaluating coverage during the Annual Enrollment Period (October 15 – December 7), this tool gives you a clear starting point for understanding your options and the tradeoffs involved before you speak with a licensed broker or visit Medicare.gov.
Medicare Advantage vs Original Medicare: Key Differences
**Original Medicare** is the federal program that includes Part A (hospital insurance) and Part B (medical insurance). It covers most hospitals, doctors, and outpatient services nationwide. There is no out-of-pocket maximum, meaning your costs in a catastrophic year are theoretically unlimited unless you add a supplement. Original Medicare does not include prescription drug coverage — you must add a standalone Part D plan.
**Medicare Advantage (Part C)** is offered by private insurers approved by Medicare. These plans bundle Part A, Part B, and usually Part D into one plan. Most are HMO or PPO plans with provider networks. You must generally use in-network providers, which can be a limitation if you travel frequently or live in a rural area. However, Medicare Advantage plans often include extra benefits like dental, vision, hearing, and gym memberships that Original Medicare does not cover.
**Key tradeoffs:** - Original Medicare offers the widest provider access (any Medicare-accepting provider in the US) - Medicare Advantage often has lower monthly premiums but may have higher copays when you use services - Medicare Advantage plans have a federally mandated annual out-of-pocket maximum; Original Medicare does not - Switching from Medicare Advantage back to Original Medicare may be difficult if you develop health conditions, since Medigap insurers can use medical underwriting outside of initial enrollment in most states
Understanding Medigap (Medicare Supplement)
Medigap plans are sold by private insurers to fill the "gaps" in Original Medicare — specifically the 20% coinsurance for Part B services, the Part A hospital deductible, and various other cost-sharing. Plans are standardized by letter (A, B, C, D, F, G, K, L, M, N) and offer the same basic benefits from any insurer; the difference is price and customer service.
**Most popular plans:** - **Plan G** is the most comprehensive plan available to people newly eligible for Medicare. It covers nearly everything except the Part B deductible, making your costs very predictable. - **Plan N** has lower premiums than Plan G but requires copays for some office and emergency room visits. - **Plan F** is no longer available to people who became eligible for Medicare after January 1, 2020, but remains available to those enrolled before that date. - **Plans K and L** have lower premiums but only cover a percentage of cost-sharing, leaving you with more exposure.
Medigap premiums are typically community-rated (same price for all ages), issue-age-rated (based on your age when you buy), or attained-age-rated (increases as you get older). Issue-age-rated plans in many states can be the most economical long-term. You must enroll during your 6-month Medigap Open Enrollment Period (starting the month you turn 65 and are enrolled in Part B) to avoid medical underwriting.
Medicare Part D: Drug Coverage
Part D plans cover prescription drugs. They are offered by private insurers and vary widely in which drugs they cover (the formulary), what tier each drug is on, and what your copays or coinsurance will be.
**How Part D works:** - Each plan has a formulary — a list of covered drugs organized into tiers. Lower tiers (generic drugs) have lower cost-sharing; higher tiers (specialty drugs) can be expensive. - There is an annual deductible (up to the Medicare-set maximum, which changes yearly) and then cost-sharing until you reach catastrophic coverage. - The Inflation Reduction Act capped out-of-pocket drug costs at \$2,000 per year starting in 2025, eliminating the previous "coverage gap" (donut hole).
If you take multiple or high-cost medications, comparing Part D formularies is critical. A plan with a slightly higher premium may save significant money if it places your drugs on a more favorable tier. Medicare's Plan Finder tool at Medicare.gov allows you to enter your specific drugs and compare costs across available plans in your zip code.
How to choose the right Medicare plan
The right Medicare path depends on several personal factors:
**Choose Original Medicare + Medigap + Part D if:** - You have complex health conditions requiring frequent specialist care - You want to see any doctor in the US without referrals - You travel frequently or spend time in multiple states - Predictability matters more than lowest monthly premiums - You can afford higher monthly premiums in exchange for minimal cost-sharing when you use care
**Choose Medicare Advantage if:** - You are generally healthy and use relatively few services - You prefer a lower monthly premium and are comfortable with a network - You value bundled benefits like dental, vision, or fitness programs - You live in an area with strong plan options and broad networks - You are comfortable with copays and prior authorization requirements
**Financial health considerations:** - If you have limited income, you may qualify for Extra Help (Low Income Subsidy) for Part D costs, or Medicare Savings Programs that reduce Part B premiums and cost-sharing - Higher-income beneficiaries pay Income-Related Monthly Adjustment Amounts (IRMAA) on top of standard Part B and Part D premiums

FAQs
Q: What is Medicare Advantage? A: Medicare Advantage (Part C) is an alternative to Original Medicare offered by private insurers approved by Medicare. These plans bundle hospital coverage (Part A), medical coverage (Part B), and usually prescription drug coverage (Part D) into a single plan. They often include extra benefits like dental, vision, and hearing that Original Medicare doesn't cover. Most plans use provider networks (HMO or PPO) and have an annual out-of-pocket maximum.
Q: Is Medicare Advantage better than Original Medicare? A: It depends on your individual health needs, financial situation, and location. Medicare Advantage often has lower monthly premiums and includes extra benefits, making it attractive for relatively healthy beneficiaries. However, network restrictions and prior authorization requirements can be challenging for people with complex conditions. Original Medicare with a Medigap supplement offers broader provider access and more predictable costs if you use healthcare frequently.
Q: What does Medigap cover? A: Medigap (Medicare Supplement) plans cover the cost-sharing gaps in Original Medicare — primarily the 20% Part B coinsurance, the Part A hospital deductible, and in some plans, excess charges and foreign travel emergencies. Plans are standardized by letter. Plan G, the most popular among new enrollees, covers virtually everything except the annual Part B deductible, giving you very predictable costs throughout the year.
Q: Can I switch Medicare plans anytime? A: No. You can switch Medicare Advantage plans or drop Medicare Advantage and return to Original Medicare during the Annual Enrollment Period (October 15 – December 7) or the Medicare Advantage Open Enrollment Period (January 1 – March 31). Switching from Medicare Advantage to Original Medicare + Medigap is possible, but Medigap insurers in most states can use medical underwriting outside your initial enrollment window, meaning you could be denied or charged higher premiums if you have health conditions.
Q: Does Medicare Advantage include drug coverage? A: Most Medicare Advantage plans include prescription drug coverage (MAPD plans). However, some Medicare Advantage plans do not include drug coverage, requiring you to enroll in a separate Part D plan. If your Medicare Advantage plan includes drug coverage, you cannot also enroll in a standalone Part D plan. Always check whether a specific plan includes Part D before enrolling.
