Common Medical Expenses Medicare Won’t Cover in 2027

Original Medicare covers a lot, but routine dental, vision, hearing, caregiving, and travel costs could still hit your wallet.

Your Medicare card might cover a lot, but it isn't a blank check. Routine health needs you think of as basic could still land on your household budget in 2027.

If you're reviewing 2027 coverage during Medicare open enrollment and determining how to save money in retirement, the calendar matters. The enrollment window runs from October 15 through December 7, 2026, and 2027 coverage is scheduled to start January 1, 2027.

The big question is where Original Medicare might stop paying and what you can do before a bill shows up.

Many successful investors eventually reach the same moment. The saving is done, the portfolio is built, and the question quietly changes from how much can I grow this to how much can I take out? Get that second question wrong and decades of good investing can come apart in a handful of years.

That is exactly what The Definitive Guide to Retirement Income helps answer.1 It covers what your retirement could actually cost, which income sources are worth using, and the withdrawal math that decides whether the money lasts. It is free today from Fisher Investments. Read More Here ›

2027 choices

Original Medicare generally covers hospital and medical care through Part A and Part B. It doesn't bundle many routine benefits into one package, so a gap that sounds small early in retirement could become a recurring line item.

Medicare Advantage plans often offer extra benefits Original Medicare doesn't, including dental, vision, or hearing allowances. Those benefits vary by plan, and the trade-offs could include networks, referrals, prior authorization, and different out-of-pocket rules.

Medigap works differently. It might help pay Original Medicare deductibles, coinsurance, and copays, but it generally isn't a substitute for dental, vision, hearing, or long-term care coverage.

Fall open enrollment doesn't guarantee that you can buy a Medigap policy. Outside your initial Medigap enrollment period, insurers may use medical underwriting unless federal protections or additional rights under state law apply.

Even covered care can leave substantial bills. Original Medicare has no annual out-of-pocket limit, so supplemental coverage can be important for managing your share of covered costs.

Reviewing Medicare prescription and procedure coverage gaps could also help you identify costs to plan for before treatment begins.

Dental work

Original Medicare generally doesn't cover most dental care. That includes routine cleanings, fillings, tooth extractions, dentures, dental plates, and other dental devices.

Certain dental services could be covered when they're closely tied to covered medical treatment. That exception doesn't erase the routine dental gap, so plan as if ordinary dental work is your expense unless your plan document says otherwise.

If dental bills are a concern, compare the annual maximum, network rules, covered services, and waiting periods on any dental benefit you consider. A plan that advertises dental coverage could still leave you paying a large share for crowns, implants, or dentures.

Vision needs

Original Medicare generally doesn't cover routine eye exams for eyeglasses or contact lenses. It also generally doesn't cover eyeglasses or contacts, except for one pair of corrective lenses after cataract surgery with an implanted intraocular lens.

That means the gap exists mainly for everyday vision maintenance. Medical eye care is a different category, and Medicare might cover certain tests or treatments when they're medically necessary.

For budgeting, separate the exam from the eyewear. A low-cost vision allowance might help with an exam but leave you with a smaller discount on progressive lenses, specialty contacts, premium frames, or contact lens fittings.

Released: The Definitive Guide to Retirement Income (Sponsor)

Most people spend their entire working lives focusing on one thing: growing a pile of money. Then they retire and discover the skill they actually need is close to the opposite. Turning that pile into steady income, year after year, through good markets and bad, without ever running out. It may be the least discussed and most consequential transition in personal finance, and plenty of otherwise careful investors walk into it with no real plan.

That is exactly what The Definitive Guide to Retirement Income helps answer.1 It is a free guide from Fisher Investments covering what your retirement will really cost, where the cash flow should come from, and how much you can safely withdraw each year. Learn More Here ›

Hearing aids

Original Medicare generally doesn't cover hearing aids. It also generally doesn't cover eyeglasses or contacts, except for one pair of eyeglasses with standard frames or one set of contact lenses after each cataract surgery that implants an intraocular lens. The Part B deductible and coinsurance apply.

Medicare Part B covers diagnostic hearing and balance exams ordered by a doctor or other health care provider to determine whether medical treatment is needed. Certain diagnostic audiology services are also covered once every 12 months without an order, including services for hearing loss that develops gradually.

If you expect hearing costs in 2027, look beyond the sticker price of the device. Batteries, charging equipment, fittings, follow-up visits, warranties, and replacement schedules could affect your real cost.

Long-term help

Original Medicare doesn't cover long-term custodial care when that's the only care you need. Custodial care usually means help with daily activities such as bathing, dressing, eating, and moving around safely.

Medicare Part A might cover skilled nursing facility care for a limited time when Medicare conditions are met. That doesn't mean open-ended nursing home coverage or ongoing in-home personal care.

This is one of the biggest budget risks because the need could arrive suddenly. If you have savings, a family caregiving plan, long-term care insurance, Medicaid planning questions, or home modifications to consider, discuss this gap before a crisis.

Travel coverage

Original Medicare generally doesn't cover health care outside the U.S. and its territories, except in limited situations. That makes international travel a real coverage gap, not just a fine-print issue.

Some supplemental coverage or travel medical insurance might help, but limits matter. Check whether a policy covers emergency care, medical evacuation, pre-existing conditions, trip length, and the country you plan to visit.

Domestic travel raises a different issue. Original Medicare generally travels with you to providers who accept Medicare, while Medicare Advantage plan rules could depend on networks, service areas, and emergency or urgent-care provisions.

Routine extras

Original Medicare also generally excludes some services you might think of as comfort care or routine maintenance. Examples include routine foot care and most cosmetic surgery, although specific exceptions apply. Original Medicare also doesn't cover massage therapy.

Medicare may cover certain foot treatments or reconstructive procedures when its coverage requirements are met. Medical necessity alone doesn't make every excluded service eligible for coverage.

Before you book a recurring service, ask the provider how it's billed and whether Medicare is expected to pay. If the answer is unclear, request the estimate in writing so the cost doesn't ambush your monthly cash flow.

Bottom line

Medicare might be a major piece of your retirement plan, but it doesn't cover every routine need. Dental work, eyewear, hearing aids, long-term custodial care, overseas medical bills, and some routine extras could still belong in your 2027 budget.

Before open enrollment ends, compare your current coverage with the services you realistically use. Read the plan's evidence of coverage, check provider networks, and focus on the benefits that match your life, not the ones that only look good on a mailer.

The best plan isn't always the one with the longest list of extras. It's the one that gives you fewer unpleasant surprises when the bill arrives.
