What Healthcare Really Costs as You Age: A State-by-State Reality Check

If you're on Medicare and you think your healthcare costs are mostly covered, the numbers may surprise you. The reality of what Americans spend on healthcare rises steadily with age, and for people 65 and older, the financial exposure can be substantial — even with Medicare in place. Understanding what you're likely to spend, and how that varies depending on where you live, is one of the most important financial planning steps a Medicare beneficiary can take.

Nationally, adults between 65 and 74 spend an average of roughly $6,000 to $7,500 per year on total out-of-pocket healthcare costs when you factor in premiums, deductibles, copays, and services Medicare doesn't cover at all — like routine dental, vision, and hearing care. By the time someone reaches their mid-to-late 70s, that figure typically climbs higher, and for those managing multiple chronic conditions or facing a serious hospitalization, annual costs can easily reach $10,000 to $15,000 or more. These aren't worst-case scenarios — they reflect what happens when Medicare's built-in cost-sharing kicks in without any supplemental protection in place.

Original Medicare — Parts A and B — was never designed to be a complete coverage solution. Part A, which covers hospital stays, carries a deductible of $1,676 per benefit period in 2025. Critically, that's not an annual deductible — it resets every time you begin a new benefit period, meaning a beneficiary who is hospitalized twice in a year could owe that deductible twice. After 60 days in the hospital, daily coinsurance of $419 kicks in, and after 90 days, you're drawing down on lifetime reserve days at $838 per day. Part B, which covers outpatient care, charges a standard premium of $185 per month in 2025 plus a $257 annual deductible, and then you're responsible for 20% of all covered services with no out-of-pocket maximum. That 20% with no cap is where people get into serious financial trouble.

The geographic variation in healthcare costs across the United States is striking and has real consequences for how much supplemental coverage you need. States in the Mountain West and parts of the rural South and Midwest tend to have higher per-capita healthcare spending, driven by a combination of provider shortages, higher rates of chronic disease, and less competitive insurance markets. Alaska consistently ranks among the most expensive states for healthcare delivery — provider costs there can run 50% to 100% higher than the national average, meaning that 20% coinsurance under Part B translates into much larger dollar amounts for Alaskans than for someone receiving the same procedure in, say, Minnesota or Hawaii, which tend to have more integrated health systems and lower baseline costs. For Medicare Advantage enrollees, this matters because plan networks, premiums, and maximum out-of-pocket limits — which can range from under $2,000 to the federal ceiling of $9,350 for in-network costs in 2025 — vary significantly by county and state.

For beneficiaries on Original Medicare, a Medigap (Medicare Supplement) policy is the most direct way to cap these unpredictable costs. Medigap Plan G, currently the most comprehensive plan available to new Medicare enrollees (Plan F was discontinued for those newly eligible after January 1, 2020), covers the Part A deductible, all hospital coinsurance, the Part B 20% coinsurance, and foreign travel emergency care, among other benefits. In 2025, monthly premiums for Plan G vary widely by state, age, and tobacco use — a 65-year-old non-smoker might pay $120 to $160 per month in a lower-cost state like Iowa or Wisconsin, while the same person in Florida or New York could pay $180 to $250 or more. High-Deductible Plan G is a lower-premium alternative that requires you to pay the first $2,870 in covered costs (the 2025 high-deductible threshold) before the plan kicks in, which can work well for healthier beneficiaries who want catastrophic protection without high monthly premiums.

State rules around Medigap enrollment can significantly affect your options and costs. In most states, you have a one-time guaranteed issue window — typically six months starting when you're both 65 and enrolled in Part B — during which insurers cannot deny you coverage or charge you more based on your health history. Miss that window, and in most states you can be medically underwritten, meaning a history of heart disease, diabetes, or cancer could result in higher premiums or outright denial. However, thirteen states have enacted the birthday rule, which gives beneficiaries a 30-day window each year around their birthday to switch to an equal or lesser Medigap plan without medical underwriting. Those states are California, Idaho, Illinois, Kentucky, Louisiana, Maine, Maryland, Missouri, Nevada, New Jersey, New York, Oklahoma, and Oregon. If you live in one of these states and you're currently in a higher-premium plan, your birthday window may be an opportunity to shop for better pricing.

Final expense insurance — typically whole life policies with face values between $5,000 and $25,000 — occupies a different but related space in the financial planning picture for older adults. These policies are designed to cover funeral and burial costs, which nationally average $8,000 to $12,000 for a traditional funeral with burial, and to prevent those costs from falling on surviving family members. Unlike Medigap, final expense policies don't help with medical bills during your lifetime, but they address a real and often overlooked financial burden. Premiums are based on age and health at the time of application — a 70-year-old in average health might pay $50 to $100 per month for a $10,000 policy, while a 78-year-old could pay $120 to $200 or more for the same coverage. Guaranteed issue final expense policies, which require no health questions, are available but carry higher premiums and typically include a two-year graded benefit period during which the full death benefit isn't paid for non-accidental death.

Hospital indemnity plans are another layer of protection worth understanding, particularly for Medicare Advantage enrollees who face daily copays for hospital stays. These plans pay a fixed cash benefit — often $100 to $300 per day — for each day you're hospitalized, which can offset the per-day copays that many Medicare Advantage plans charge after the first day or two. In states with higher hospitalization rates among seniors, such as Mississippi, West Virginia, and Kentucky, having this kind of fixed-benefit backstop can meaningfully reduce financial stress during a serious illness.

The honest bottom line is this: Medicare is a foundation, not a complete financial safety net. The combination of rising costs with age, significant geographic variation in what healthcare actually costs, and Medicare's built-in gaps — particularly the unlimited 20% Part B coinsurance — means that most beneficiaries benefit from some form of supplemental coverage. The right choice depends on your health, your budget, your state's rules, and whether you're on Original Medicare or a Medicare Advantage plan.
