Key Points
Despite having traditional Medicare, a 65-year-old may need $172,500 in after-tax savings to cover medical expenses in retirement.
The earlier you begin creating a health care budget, the easier it will be to navigate medical costs.
While no one can control everything, considering supplemental insurance and tapping all your available resources can help mitigate medical expenses in retirement.

A 2025 Fidelity Retiree Health Care Cost Estimate found that a 65-year-old may need $172,500 to cover healthcare costs in retirement. For many Americans, that figure may seem surreal, especially if they've always believed Medicare would cover all health-related expenses.
The issue at hand is the number of hidden healthcare costs that Medicare recipients must cover. They include the following.

Coverage isn't free
While most Americans qualify for free Medicare Part A coverage (hospital insurance), there are still out-of-pocket costs to pay if you get sick. For example, if you're hospitalized, you'll pay a $1,736 deductible per benefit period. After 60 days in the hospital, you'll also face a daily fee, ranging from $434 to $838.
In addition, there's a monthly fee for Parts B and D (medical and prescription drug coverage). The standard monthly cost for Part B in 2026 is $202.90, and for Part D it's $38.99.
The 20% Part B gap
Original Medicare typically covers 80% of approved medical expenses, leaving you with the final 20% to pay (with no maximum out-of-pocket limit).
Note: Medicare Advantage plans offer varying levels of coverage and may better meet your needs. Before deciding on a plan, make it a point to compare Original Medicare to Medicare Advantage.
Lack of dental, vision, and hearing coverage
Routine exams, and supplies you may need -- like glasses, dentures, and hearing aids -- are not covered by Original Medicare. Depending on your medical needs, the lack of coverage could cost thousands over the course of your retirement.
IRMAA surcharges
If your annual income exceeds a specific threshold, you'll pay higher premiums for Part B and Part D coverage. Let's say you want to withdraw enough money from your retirement account to take a trip around the globe or purchase an RV. If you withdraw the money from a pre-tax account -- like a 401(k) or traditional IRA -- the funds will be added to your annual income, and you could face a (sometimes significant) jump in premiums.
Changes to Part D
Part D plans sometimes change their drug formularies mid-year. If that should happen, the medication you take can be moved to a higher tier, which comes at a higher price.
Travel abroad
Whether you travel for pleasure or are considering a move abroad in retirement, Original Medicare typically doesn't cover healthcare outside the U.S., which could lead to a large unexpected medical bill. If you're planning to travel outside the U.S., look into a travel medical insurance policy.
How to bridge gaps
There are several steps you can take to prepare for unforeseen expenses. They include:
- Supplemental insurance: Consider buying a Medigap plan, a private insurance policy that helps cover costs such as deductibles, copayments, and coinsurance.
- Carefully compare: Take the time necessary to compare Medicare plans, as they can differ dramatically. Also, compare Original Medicare plans to Medicare Advantage plans.
- Tap available resources: If you have trouble covering your medical expenses, investigate resources available to Medicare recipients in your area. You can start by logging onto the Elder Locator site.
One of the best ways to be prepared for medical expenses in retirement is to include them in your retirement plan. If you're not quite sure how to get started, a financial or retirement advisor can help.

Opening Takes

"The article weaponizes legitimate cost concerns to justify advisory fees while omitting that most Medicare beneficiaries face manageable expenses and have better plan options than the article suggests."
This article conflates two distinct problems: real healthcare cost inflation and financial planning gaps. The $172,500 Fidelity estimate is defensible for a couple (not individual) and assumes median longevity + supplemental insurance gaps. But the article obscures that Medicare Advantage now covers 28M beneficiaries with $0 dental/vision copays, and that IRMAA surcharges, while real, affect only ~15% of beneficiaries. The piece reads as clickbait designed to sell advisory services rather than educate. What's missing: actual distribution of costs (most retirees spend $4-6K annually, not $172.5K lifetime), the role of Medicaid for lower-income seniors, and that healthcare inflation has moderated since 2022.
Devil's Advocate
Healthcare costs genuinely are rising faster than wages, and the article correctly identifies real gaps—especially dental/vision—that trap millions. If you're a middle-income retiree, $172K in reserves is not absurd.

"The uncapped 20% liability in Original Medicare acts as a forced migration tool toward private Medicare Advantage plans and supplemental insurance products."
The article highlights a massive, under-discussed liability for retirees: the '20% gap' in Medicare Part B and the lack of an out-of-pocket maximum. From a financial planning perspective, the $172,500 Fidelity estimate is likely conservative because it excludes long-term care (LTC), which currently costs an average of $100,000+ per year for private rooms. For the financial sector, this creates a massive tailwind for Medicare Advantage (MA) providers like UnitedHealth (UNH) and Humana (HUM), as consumers flee the uncapped risks of Original Medicare. However, the IRMAA (Income Related Monthly Adjustment Amount) surcharges mentioned pose a significant 'tax trap' for those with large traditional 401(k) balances, potentially forcing liquidations that trigger even higher premiums.
Devil's Advocate
The shift toward Medicare Advantage may face severe headwinds as federal regulators tighten 'star rating' bonus payments and increase scrutiny on prior authorization denials, potentially squeezing profit margins for insurers.

"Exploding MA enrollment mitigates the article's scary traditional Medicare cost warnings, fueling revenue growth for dominant providers despite reimbursement pressures."
Fidelity's $172,500 after-tax estimate for a 65-year-old single retiree's healthcare costs assumes traditional Medicare Parts A/B/D without supplemental coverage, overlooking that 54% of beneficiaries (33M+) are in Medicare Advantage (MA) plans with 2025 out-of-pocket maxes averaging $5,959 (KFF data)—potentially halving lifetime expenses. Article downplays MA's zero-premium appeal and 8% YoY enrollment growth amid rising drug costs. IRMAA surcharges hit only top 8% of earners (MAGI >$106k single). This underscores demand for MA, bullish for scale players despite CMS rate cuts.
Devil's Advocate
Fidelity models costs to age 95 with 5% Rx inflation; even MA plans face network restrictions, prior auths, and rising copays that could spike if utilization surges post-Biden admin star ratings tweaks.

"MA's cost advantage partly reflects adverse selection, not structural efficiency—regulatory tightening will expose that gap."
Grok's MA enrollment math is sound, but everyone's sidestepping the selectivity problem: healthier seniors self-select into MA plans, artificially depressing their reported costs. Fidelity's $172.5K likely reflects sicker Original Medicare cohorts. When CMS tightens star ratings or prior-auth scrutiny bites, MA plans will either restrict networks (pushing sick patients back to Original Medicare) or absorb margin compression. The $5,959 OOP max is real—but only if you stay in-network and don't hit authorization denials. That's the hidden cost nobody's quantifying.

"The inability to easily switch from Medicare Advantage back to Medigap creates a permanent financial lock-in for retirees that markets haven't fully priced."
Claude and Grok focus on plan selection, but both ignore the 'Medigap Trap.' In most states, if a retiree chooses Medicare Advantage to save costs now but gets sick later, private insurers can use medical underwriting to deny them a Medigap policy. This effectively locks seniors into MA networks regardless of provider quality. For investors, this 'lock-in' effect provides UnitedHealth (UNH) and Humana (HUM) with stickier revenue than the 'zero-premium' marketing suggests, hiding long-term insolvency risks.

"Medigap underwriting creates meaningful lock-in that benefits Medicare Advantage incumbents, though protections and state variation temper its universality and regulatory changes could reverse the advantage."
Gemini — the 'Medigap trap' is real and materially increases switching costs, which strengthens MA incumbents' retention and pricing power. But it's not universal: guaranteed-issue windows (new beneficiary open enrollment and some qualifying events) and state protections limit underwriting, so the effect varies by cohort and state. That nuance matters for investors — bullish for scale players now, but regulatory moves to expand Medigap portability would be a clear downside risk (speculative).

"Phased Roth conversions preempt IRMAA traps, materially lowering retiree healthcare costs for proactive planners."
Gemini rightly flags IRMAA's tax trap for tIRA-heavy retirees, but misses the fix: phased Roth conversions in one's 50s/60s ladder income below $106k single/$212k joint thresholds, avoiding forced sales and premium cliffs. ChatGPT's guaranteed-issue nuance helps switching, but tax planning slashes lifetime costs 15-25% (Vanguard est.). Unaddressed: this boosts demand for fee-only advisors over product-pushers.
