Most people approaching retirement assume Medicare will cover the bulk of their medical costs — and most people are wrong. The average retiree will spend $165,000 or more out-of-pocket on healthcare after age 65, according to Fidelity’s 2023 Retiree Health Care Cost Estimate. That number doesn’t include long-term care. Understanding Medicare costs retirement planning demands is no longer optional — it’s one of the most consequential financial decisions you’ll ever make.
The scope of the problem is staggering. Medicare spending reached $944 billion in 2022, yet enrollees still shoulder enormous personal cost burdens. Part B premiums alone reached $174.70 per month in 2024 — a 6% jump from 2023. Add in deductibles, copays, Medigap policies, and prescription drug costs, and a retired couple could easily spend $500–$700 per month just on premiums. Meanwhile, 64% of retirees say healthcare costs were higher than expected, according to the Employee Benefit Research Institute.
This guide breaks down every cost layer of Medicare — Parts A, B, C, and D — along with Medigap coverage, IRMAA surcharges, and the enrollment rules that can permanently raise your premiums if you miss them. You’ll walk away with specific numbers, real comparisons, and a concrete action plan to make smarter Medicare decisions before and after you enroll.
Key Takeaways
- The average retired couple will need approximately $315,000 saved specifically for healthcare costs in retirement, per Fidelity’s 2023 estimate.
- Medicare Part B premiums in 2024 are $174.70/month — but high earners pay up to $594.00/month due to IRMAA income-related surcharges.
- Missing the Medicare Part B enrollment window can trigger a 10% permanent premium penalty for every 12-month period you were eligible but didn’t enroll.
- Medicare Advantage (Part C) plans average $18.50/month in 2024, but can carry higher out-of-pocket maximums of up to $8,850 for in-network care.
- A standalone Part D prescription drug plan averages $48/month in 2024, with the Medicare catastrophic drug cap now set at $2,000 out-of-pocket annually starting in 2025.
- Health Savings Accounts (HSAs) cannot receive new contributions once you enroll in Medicare — making pre-retirement HSA maximization a critical strategy.

Medicare Basics: What the Program Actually Covers
Medicare is a federal health insurance program primarily for Americans aged 65 and older. It also covers certain younger people with disabilities and those with End-Stage Renal Disease (ESRD).
The program is divided into distinct parts, each covering a different category of care. Understanding which part covers what is the foundation of intelligent Medicare planning.
The Four Parts of Medicare
Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health services. Most people receive Part A premium-free if they or a spouse paid Medicare taxes for at least 10 years (40 quarters).
Part B covers outpatient care — doctor visits, preventive services, lab tests, durable medical equipment, and outpatient surgeries. Part B always carries a monthly premium.
Part C, known as Medicare Advantage, is an alternative way to receive Parts A and B benefits through a private insurer. These plans often bundle Part D drug coverage as well.
Part D provides prescription drug coverage through private plans approved by Medicare. It operates separately from Parts A and B and carries its own premiums and cost-sharing structure.
What Medicare Does NOT Cover
Medicare does not cover dental, vision, hearing aids, or custodial long-term care. This surprises many enrollees who assume comprehensive coverage after a lifetime of payroll taxes.
Long-term care — the cost of assisted living or nursing home care — is one of the largest uncovered expenses retirees face. The Administration for Community Living estimates that 70% of people turning 65 will need some form of long-term care, with an average need of three years.
Medicare covers only short-term skilled nursing facility stays (up to 100 days per benefit period) — and only under specific conditions. It does not pay for custodial care, which is the type of help most people eventually need.
Part A Costs: Hospital Coverage and What You’ll Still Owe
While most enrollees pay $0 in Part A premiums, the program is far from free once you’re hospitalized. The cost structure is built around benefit periods and deductibles rather than premiums.
In 2024, the Part A inpatient hospital deductible is $1,632 per benefit period — not per year. A benefit period begins on the day you’re admitted and ends 60 days after discharge. If you’re readmitted after that 60-day gap, a new deductible applies.
Hospital Stay Cost Tiers
| Days in Hospital | Your Cost (2024) | Medicare Pays |
|---|---|---|
| Days 1–60 | $1,632 deductible (once per benefit period) | All remaining costs |
| Days 61–90 | $408/day coinsurance | Remaining covered costs |
| Days 91–150 | $816/day (lifetime reserve days) | Remaining covered costs |
| Beyond 150 days | 100% — you pay everything | Nothing |
Lifetime reserve days are exactly that — a one-time pool of 60 days for hospitalizations exceeding 90 days in a single benefit period. Once used, they’re gone forever.
Skilled Nursing Facility Costs
After a qualifying hospital stay of at least 3 days, Medicare covers skilled nursing facility (SNF) care. The coverage tiers are similarly structured to hospital stays.
| SNF Days | Your Cost (2024) | Medicare Pays |
|---|---|---|
| Days 1–20 | $0 | All approved costs |
| Days 21–100 | $204/day coinsurance | All remaining costs |
| Beyond Day 100 | 100% — you pay everything | Nothing |
This structure is why a single serious illness — a stroke, hip fracture, or cardiac event — can devastate a retirement budget. Days 21–100 in a skilled nursing facility cost $204/day, or $16,524 for the remainder of that coverage window.
The average cost of a private room in a skilled nursing facility was $108,405 per year in 2023, according to Genworth’s Cost of Care Survey. Medicare covers only a fraction of that — and only temporarily.
Part B Costs: The Premium Most Retirees Underestimate
Part B is where Medicare costs in retirement planning becomes most complex. Unlike Part A, Part B always requires a monthly premium — and that premium can vary dramatically based on your income.
The standard Part B premium in 2024 is $174.70 per month ($2,096.40/year). For a married couple, that’s $4,192.80 per year before any deductibles or cost-sharing kicks in.
Part B Deductibles and Coinsurance
The 2024 Part B annual deductible is $240. After meeting the deductible, Medicare generally covers 80% of approved outpatient services — leaving you responsible for the remaining 20%.
That 20% coinsurance has no annual out-of-pocket cap in original Medicare (Parts A and B alone). A single expensive procedure — say, an MRI or outpatient surgery — could leave you owing thousands with no ceiling.
| Part B Component | 2024 Amount | Who Pays |
|---|---|---|
| Standard Monthly Premium | $174.70 | Enrollee |
| Annual Deductible | $240 | Enrollee |
| Coinsurance (after deductible) | 20% of approved amount | Enrollee |
| Out-of-Pocket Cap | None (Original Medicare) | N/A |
How Premiums Are Collected
If you receive Social Security benefits, your Part B premium is automatically deducted from your monthly Social Security payment. If you’re not yet collecting Social Security, you’ll receive a quarterly bill from Medicare.
This automatic deduction is why the timing of your Social Security claim affects your Medicare experience. Delaying Social Security past 65 means paying Medicare premiums out-of-pocket until benefits begin.
“Healthcare is consistently the most underestimated expense in retirement planning. People budget for travel and housing but forget that a single hospitalization can cost more than a year’s vacation.”
IRMAA Surcharges: When Higher Income Means Higher Premiums
High-income retirees pay significantly more for Medicare. The Income-Related Monthly Adjustment Amount (IRMAA) is a surcharge added to Part B and Part D premiums based on your Modified Adjusted Gross Income (MAGI) from two years prior.
For 2024 premiums, Medicare uses your 2022 tax return. This two-year lookback creates a planning window — but also surprises many retirees who had a one-time high-income year (like a Roth conversion or property sale) that triggers IRMAA the following two years.
2024 IRMAA Brackets and Part B Premiums
| 2022 Individual MAGI | 2022 Joint MAGI | 2024 Monthly Part B Premium |
|---|---|---|
| Up to $103,000 | Up to $206,000 | $174.70 |
| $103,001–$129,000 | $206,001–$258,000 | $244.60 |
| $129,001–$161,000 | $258,001–$322,000 | $349.40 |
| $161,001–$193,000 | $322,001–$386,000 | $454.20 |
| $193,001–$500,000 | $386,001–$750,000 | $559.00 |
| Above $500,000 | Above $750,000 | $594.00 |
A retiree with a joint MAGI of $260,000 in 2022 pays $349.40/month for Part B in 2024 — double the standard premium. For a couple, that’s $698.80/month just for Part B, versus $349.40/month at standard rates.
IRMAA Appeals: When You Can Fight Back
If your income dropped significantly since the base year (due to retirement, divorce, death of a spouse, or other life changes), you can appeal your IRMAA determination using Form SSA-44. The Social Security Administration adjudicates these appeals.
Successful appeals can reduce your premium immediately — sometimes by hundreds of dollars per month. This is especially relevant for new retirees whose income drops sharply in the first year after leaving work.
Large Roth IRA conversions, required minimum distributions from IRAs, or a one-time capital gains event can push you into a higher IRMAA bracket — even if that income won’t recur. Work with a tax advisor before executing major financial transactions in pre-retirement years. For more on RMD planning, see Required Minimum Distributions Explained.
Medicare Advantage (Part C): Pros, Cons, and Real Costs
Medicare Advantage is an all-in-one alternative to original Medicare offered by private insurers. In 2024, more than 54% of Medicare-eligible beneficiaries enrolled in Medicare Advantage, according to KFF.
These plans must cover everything original Medicare covers — but they can also add benefits like dental, vision, hearing, and gym memberships. The tradeoff is a network restriction and prior authorization requirements that original Medicare doesn’t impose.
Medicare Advantage Cost Structure
The average Medicare Advantage premium in 2024 is $18.50/month — far below the Part B standard premium. But that comparison is misleading. You still pay the Part B premium on top of the Advantage plan premium, and cost-sharing at the point of care can be significantly higher.
Medicare Advantage plans cap your annual out-of-pocket expenses. The 2024 maximum out-of-pocket limit for in-network services is $8,850. Some plans set this limit lower as a competitive feature.
Medicare Advantage vs. Original Medicare: Side by Side
| Feature | Original Medicare (A+B) | Medicare Advantage (Part C) |
|---|---|---|
| Monthly Premium | $174.70 (Part B only) | $174.70 + plan premium (avg. $18.50) |
| Annual Out-of-Pocket Cap | None | Up to $8,850 (in-network) |
| Provider Network | Any Medicare-accepting provider | Network restricted (HMO/PPO) |
| Referrals Required | No | Often yes (HMO plans) |
| Extra Benefits | None | Often dental, vision, hearing |
| Prior Authorization | Rarely | Frequently required |
The appeal of Medicare Advantage is real — lower premiums and an out-of-pocket cap provide budget predictability. But the network restrictions can become a serious problem if you develop a complex condition requiring specialist care outside the plan’s network.
Medicare Advantage plans are allowed to deny services that original Medicare would cover if they determine the care isn’t “medically necessary” under their own criteria. A 2022 HHS Office of Inspector General report found that 13% of denied prior authorization requests in Medicare Advantage were for services that met Medicare coverage rules.
Part D Drug Costs: What You Pay at the Pharmacy
Prescription drugs are among the most significant Medicare costs in retirement. Medicare Part D covers outpatient prescription drugs through private plans — either standalone plans (PDP) or as part of a Medicare Advantage plan.
The average standalone Part D premium in 2024 is approximately $48/month. But the real cost depends heavily on which drugs you take and which tier they occupy in your plan’s formulary.
The Part D Cost-Sharing Tiers
Part D plans use a tiered formulary system. Generic drugs sit in lower tiers with modest copays; brand-name and specialty drugs climb into higher tiers with substantial cost-sharing.
The 2024 Part D deductible can be up to $545. After the deductible, you pay a share of drug costs until you reach the out-of-pocket threshold. Beginning in 2025, the Inflation Reduction Act caps annual out-of-pocket drug costs at $2,000 — a major change from prior years.
Starting January 1, 2025, Medicare Part D enrollees will pay no more than $2,000 out-of-pocket annually for covered prescription drugs — down from a prior catastrophic threshold that could exceed $8,000 in total drug spending.
Comparing Part D Plan Options
Choosing the wrong Part D plan can cost hundreds of dollars per year. Plans covering the same geographic area can differ by $30–$80/month in premium, and formularies vary significantly. Medicare’s Plan Finder tool at Medicare.gov lets you compare plans based on your specific medications.
You must reassess your Part D plan every year during Open Enrollment (October 15–December 7). Formularies, premiums, and drug tiers change annually — a plan that was optimal last year may not be this year.
“People pick a Part D plan once and forget about it. Five years later, they’re paying hundreds more than necessary for the same drugs because they never switched plans during Open Enrollment.”
Medigap Supplemental Insurance: Closing the Coverage Gaps
Original Medicare’s lack of an out-of-pocket cap is a serious financial risk. Medigap (also called Medicare Supplement Insurance) fills the gaps left by Parts A and B — covering deductibles, coinsurance, and in some plans, foreign travel emergencies.
Medigap plans are sold by private insurers and are standardized by the federal government. Plans with the same letter name (A, B, C, D, F, G, K, L, M, N) offer identical benefits regardless of insurer. The only difference is the premium.
Most Popular Medigap Plans Compared
| Plan | Part A Deductible | Part B Deductible | Part B Coinsurance | Avg. Monthly Premium |
|---|---|---|---|---|
| Plan F | Covered | Covered | Covered | $150–$200+ (new enrollees ineligible) |
| Plan G | Covered | Not covered | Covered | $100–$170 |
| Plan N | Covered | Not covered | Covered (with copays) | $75–$130 |
| Plan K | 50% covered | Not covered | 50% covered | $50–$80 |
Plan G is currently the most comprehensive plan available to new Medicare enrollees (Plan F was closed to those who became eligible after January 1, 2020). Plan G covers virtually everything except the Part B deductible ($240 in 2024).
When to Buy Medigap: Open Enrollment Advantage
The best time to buy Medigap is during your Medigap Open Enrollment Period — the six-month window starting the month you turn 65 and enroll in Part B. During this period, insurers must sell you any Medigap policy they offer at standard rates, regardless of your health history.
After this window closes, insurers in most states can use medical underwriting — meaning they can charge you more or deny coverage based on pre-existing conditions. Waiting can permanently limit your Medigap options.
Compare at least three Medigap insurers for the same plan letter. Premiums for identical coverage can differ by 30-50% depending on the company’s pricing methodology (attained-age, issue-age, or community-rated). Use your state’s SHIP (State Health Insurance Assistance Program) counselor for free, unbiased guidance.
Enrollment Rules and Penalties: Mistakes That Follow You Forever
Medicare enrollment is governed by strict windows and permanent penalties for missing them. These rules represent some of the most consequential — and most misunderstood — aspects of Medicare costs in retirement planning.
Your Initial Enrollment Period (IEP) is a 7-month window centered on your 65th birthday: 3 months before, the month of, and 3 months after. Enrolling on time avoids penalties and ensures coverage starts promptly.
Part B Late Enrollment Penalty
If you delay Part B enrollment without a qualifying Special Enrollment Period (SEP), you face a permanent 10% premium penalty for every 12-month period you were eligible but didn’t enroll. These penalties never expire.
A retiree who delays Part B enrollment for 3 years without a qualifying exemption faces a permanent 30% premium surcharge. On a $174.70 base premium, that’s an extra $52.41 per month — $628.92 per year — for the rest of their life.
Working Past 65: The Group Coverage Exception
If you’re still working at 65 and have employer group health coverage, you may qualify for a Special Enrollment Period to delay Medicare without penalty. However, this only applies if the employer has 20 or more employees. Retirees from small employers must enroll in Medicare at 65 to avoid penalties.
Misunderstanding this rule is one of the most costly Medicare mistakes. COBRA coverage or retiree health benefits from a former employer do NOT qualify as the “active coverage” needed to defer Medicare without penalty.
If you’re covered by a spouse’s employer plan, verify that the employer has at least 20 employees before assuming you can defer Medicare without penalty. Small employer plans become secondary to Medicare once you’re 65 — and delays can trigger permanent premium surcharges.
HSA Strategy Before Medicare: The Pre-Enrollment Opportunity
A Health Savings Account (HSA) is one of the most powerful tools for managing Medicare costs in retirement — but its usefulness changes dramatically once you enroll in Medicare. Understanding the transition is essential.
Once you enroll in any part of Medicare, you can no longer make new HSA contributions. Contributions made after Medicare enrollment begin may be subject to taxes and penalties.
Maximizing HSA Contributions Before Medicare
The 2024 HSA contribution limits are $4,150 for individuals and $8,300 for families. Those aged 55 and older can add a $1,000 catch-up contribution annually. This means a couple, both 60 years old, could contribute up to $9,300 per year to an HSA.
The strategic play is to contribute the maximum to an HSA for as many years as possible before Medicare enrollment, then use those accumulated funds tax-free to pay Medicare premiums and out-of-pocket medical costs in retirement. For a deeper look at this strategy, our guide on Health Savings Accounts as a Retirement Tool covers the mechanics in full detail.
What You Can Pay for Tax-Free with an HSA in Retirement
- Medicare Part A, B, and D premiums
- Medicare Advantage plan premiums
- Medigap supplement premiums
- Dental, vision, and hearing expenses not covered by Medicare
- Deductibles, copays, and coinsurance
- Long-term care insurance premiums (up to IRS limits by age)
HSA funds used for qualified medical expenses are completely tax-free — no income tax on the way in (deductible contributions), no tax on growth, and no tax on withdrawals for medical costs. No other financial account offers this triple tax advantage.
Planning for Medicare Costs in Retirement: Building Your Budget
Understanding Medicare costs in retirement is one thing — building a realistic budget around them is another. Most financial planners recommend earmarking a dedicated healthcare budget line separate from general living expenses.
A useful framework is to estimate your annual Medicare costs in three tiers: premiums, routine out-of-pocket costs, and catastrophic reserves. Treating each separately gives you better control and prevents healthcare costs from blindsiding your overall retirement income plan.
Estimating Annual Medicare Costs for a Typical Retiree
| Cost Category | Annual Estimate (Single Retiree) | Annual Estimate (Couple) |
|---|---|---|
| Part B Premium | $2,096 | $4,192 |
| Part D Premium (avg.) | $576 | $1,152 |
| Medigap Plan G (avg.) | $1,680 | $3,360 |
| Dental/Vision/Hearing | $500–$1,500 | $1,000–$3,000 |
| Estimated Total Premiums | $4,852–$5,852 | $9,704–$11,704 |
These figures represent base-case scenarios at standard IRMAA levels. High-income retirees should add several thousand dollars to account for surcharges. And these totals exclude long-term care — a category that demands its own financial strategy.
Healthcare as a Percentage of Retirement Income
HealthView Services research suggests retirees can expect healthcare to consume 15–20% of their total retirement income. For a couple drawing $60,000/year from savings and Social Security, that’s $9,000–$12,000 annually going to healthcare costs alone.
Building this into your withdrawal strategy is critical. Our analysis of how much you need to retire comfortably addresses how healthcare inflation affects total retirement savings targets. Additionally, if you’re managing retirement cash flow tightly, learning to optimize every dollar with micro-budgeting can help stretch your retirement income further.
“The single biggest risk to retirement financial security isn’t market volatility — it’s healthcare costs that people didn’t model, didn’t budget for, and didn’t insure against adequately.”
Real-World Example: How Susan and David Avoided a $40,000 Medicare Mistake
Susan, 64, and David, 67, were planning their retirement within the same calendar year. David had already enrolled in Medicare at 65 without fully understanding IRMAA. In 2022, he and Susan executed a large Roth conversion — $120,000 — to reduce future RMDs. Their joint MAGI jumped to $310,000, triggering the third IRMAA tier. Their combined 2024 Part B premium jumped from $349.40/month to $698.80/month — an extra $4,192 annually they hadn’t budgeted for.
Susan, meanwhile, had delayed her own Medicare Part B enrollment past her Initial Enrollment Period, assuming her husband’s retiree health plan from his former employer covered her. It did — but the employer had fewer than 20 employees, meaning Medicare should have been primary. When she enrolled 18 months late, she faced a permanent 10% Part B penalty. At the standard 2024 rate, that’s an extra $17.47/month — $209/year — for life, totaling over $4,000 in cumulative excess premiums over 20 years.
After working with a Medicare specialist, they filed a successful IRMAA appeal (Form SSA-44) citing retirement income change for the following year, which reduced their IRMAA bracket. They also enrolled Susan in Medigap Plan G during her next available guaranteed-issue window, capping her future out-of-pocket exposure at the Part B deductible of $240/year. They restructured future Roth conversions to stay under the $206,000 joint MAGI threshold — saving an estimated $3,500/year in premium surcharges.
In total, proactive planning after the mistakes saved the couple an estimated $40,000 in avoidable Medicare costs over their projected 20-year retirement — not counting the peace of mind from knowing their coverage was optimized. Their story is a textbook case of why Medicare planning deserves the same attention as investment allocation.
Your Action Plan
-
Know your enrollment windows and mark every deadline
Your Initial Enrollment Period begins 3 months before your 65th birthday month and ends 3 months after. Set calendar reminders 6–12 months in advance. If you’re working past 65, verify your employer’s size and confirm your Special Enrollment Period eligibility in writing with your HR department.
-
Calculate your projected IRMAA exposure
Pull your last two years of tax returns and look at your Modified Adjusted Gross Income. Compare it to the IRMAA brackets for the year you’ll turn 65. If you’re near a bracket threshold, work with a tax advisor to determine whether Roth conversions, capital gains realizations, or other income events should be timed differently.
-
Maximize HSA contributions in the years before Medicare
Contribute the maximum to your HSA every year you’re eligible — $4,150 for individuals, $8,300 for families in 2024, plus the $1,000 catch-up if you’re 55 or older. Invest these funds for growth rather than spending them on routine medical costs if you can afford to. Every dollar in your HSA at retirement is a tax-free dollar available for Medicare premiums and out-of-pocket costs.
-
Decide between Original Medicare + Medigap vs. Medicare Advantage
Evaluate both options based on your health status, preferred providers, and financial risk tolerance. If predictability and provider choice matter most, Original Medicare with Plan G provides the broadest access and coverage. If you’re healthy and cost-focused, a Medicare Advantage plan with a low out-of-pocket maximum may work well — but review the network and prior authorization rules carefully.
-
Shop for Part D coverage annually during Open Enrollment
Use Medicare’s Plan Finder tool at Medicare.gov every year between October 15 and December 7 to compare Part D plans based on your current medications. Enter your exact drugs and dosages to get accurate cost estimates. Switching plans takes 10 minutes and can save hundreds of dollars per year.
-
Build a dedicated healthcare budget line in your retirement plan
Estimate total annual Medicare costs (premiums + out-of-pocket) and treat healthcare as a separate budget category. Plan for 3–5% annual healthcare inflation — higher than general CPI. If you’re working with a financial advisor, ask them to run a healthcare-cost scenario in your retirement projections. Understanding the most common budgeting mistakes can help you structure this planning more effectively.
-
Review your Social Security claiming strategy alongside Medicare timing
Delaying Social Security past 65 means paying Medicare Part B premiums directly (not via automatic deduction) and potentially missing the “hold harmless” protection that prevents Social Security net benefits from decreasing. Coordinate your Medicare and Social Security start dates carefully. Our guide on whether to delay Social Security benefits walks through the tradeoffs in detail.
-
Address long-term care risk separately
Medicare does not cover custodial long-term care. Research your options — long-term care insurance, hybrid life/LTC policies, or self-insuring through dedicated savings — well before you need coverage. Premiums for LTC insurance rise steeply after age 65, and health conditions can make you ineligible entirely. Start this conversation at least 5–10 years before retirement.
Frequently Asked Questions
When should I enroll in Medicare?
You should enroll during your Initial Enrollment Period — the 7-month window that starts 3 months before your 65th birthday month. Enrolling in the first 3 months of this window ensures your coverage starts the month you turn 65. Waiting until your birthday month or after causes a delay in coverage start dates.
If you’re still working and covered by a qualifying employer group plan (employer with 20+ employees), you may delay Part B without penalty until you leave work or lose that coverage. Always confirm your eligibility for a Special Enrollment Period before delaying.
Can I have both Medicare and private insurance?
Yes. Many retirees pair original Medicare (Parts A and B) with a Medigap supplement plan and a Part D drug plan. Others use Medicare Advantage, which bundles coverage under a single plan. You cannot use an HSA to make new contributions once enrolled in Medicare, but you can use existing HSA funds to pay Medicare-related costs.
What happens if I miss the Medicare enrollment deadline?
Missing Part B enrollment without a qualifying Special Enrollment Period results in a permanent 10% premium penalty for each full 12-month period you were eligible but didn’t enroll. Part D has a similar late enrollment penalty: 1% of the national base premium for each month you were without creditable drug coverage, added permanently to your premium.
Does Medicare cover dental, vision, and hearing?
Original Medicare (Parts A and B) does not cover routine dental care, most vision services, or hearing aids. Some Medicare Advantage plans include these benefits as extras. If you choose Original Medicare, budget separately for dental, vision, and hearing expenses — costs that can easily run $1,000–$3,000 per year per person without coverage.
What is the Medicare Part D coverage gap (donut hole)?
The coverage gap, or “donut hole,” was a phase in which drug coverage was reduced after you and your plan spent a certain amount. The Inflation Reduction Act of 2022 effectively closes the donut hole starting in 2025 by capping annual out-of-pocket drug costs at $2,000. In 2024, the coverage gap still technically exists, but manufacturers and plans provide significant discounts within it.
Can I switch from Medicare Advantage back to original Medicare?
Yes, you can switch during the Medicare Open Enrollment Period (October 15–December 7) or the Medicare Advantage Open Enrollment Period (January 1–March 31). However, if you switch back to original Medicare after age 65, you may not be able to get a Medigap policy in most states — insurers can deny coverage or charge more based on your health. This is a major reason to carefully evaluate your initial choice.
What is the Medicare Savings Program?
Medicare Savings Programs are state-run programs that help low-income Medicare beneficiaries pay for Part A and Part B premiums, deductibles, and coinsurance. There are four levels (QMB, SLMB, QI, and QDWI), each with different income and asset thresholds. Contact your State Medicaid office or call 1-800-MEDICARE to learn if you qualify.
How does Medicare coordinate with my spouse’s employer insurance?
Coordination depends on the size of your spouse’s employer. If your spouse works for an employer with 20 or more employees, that employer plan is primary and Medicare is secondary — meaning you can delay Medicare enrollment without penalty. For employers with fewer than 20 employees, Medicare is primary at age 65 and the employer plan is secondary, regardless of enrollment status.
What is creditable drug coverage?
Creditable drug coverage is prescription drug coverage from a source other than Medicare Part D that is at least as good as the standard Medicare Part D benefit. Employer and union plans, TRICARE, and VA coverage are common examples. Having creditable coverage allows you to delay Part D enrollment without penalty. Your coverage provider is required by law to notify you annually whether your coverage is creditable.
How can I reduce my Medicare costs?
Several strategies can lower your Medicare costs: staying below IRMAA income thresholds through tax planning, maximizing HSA contributions before enrollment, shopping Part D plans annually, applying for Medicare Savings Programs if income-eligible, and carefully comparing Medigap plan premiums across insurers for identical coverage letters. Working with a Medicare specialist or your state’s SHIP counselor (free of charge) can identify savings specific to your situation.
