The Medicare Mistake That Can Cost More Than a Higher Premium

hperson wants. Consumers attracted to a low Medicare Advantage premium should therefore understand not only today’s benefits, but also what their options may look like several years later.

Don’t Confuse Medicare With Long-Term-Care Coverage

Another costly Medicare misconception involves nursing homes and long-term care. Medicare covers medically necessary hospital services and may cover limited skilled nursing facility care when specific requirements are met. It does not generally pay for long-term custodial care when someone primarily needs assistance with everyday activities such as bathing, dressing or eating.

That distinction matters because long-term care can become one of the largest expenses in later retirement. A retiree may have excellent Medicare and Medigap coverage and still face substantial costs if years of custodial assistance are eventually required. Planning options can include paying from personal assets, purchasing traditional long-term-care insurance or evaluating hybrid policies that combine life insurance or annuity features with long-term-care benefits.

Medicaid can become another source of long-term-care funding for people who meet their state’s financial and medical eligibility requirements. Most people entering nursing homes initially pay at least some costs themselves, and Medicaid rules can consider both income and resources. Federal rules also provide protections for certain assets and for spouses who remain living in the community, which is why Medicaid planning cannot accurately be reduced to a single nationwide asset limit.

That complexity is one reason people should be wary of generic claims that everyone must simply “spend down to $2,000.” State rules, home ownership, marital status, transfers of assets and the type of Medicaid benefit being sought can all change the outcome. Long-term-care planning should therefore be treated as a separate financial-planning issue rather than assuming Medicare will solve it.

Higher Income Can Quietly Increase Medicare Costs

Even retirees who choose their health coverage carefully can be surprised by Medicare’s income-related surcharges. In 2026, the standard Part B premium is $202.90 a month. Individuals with modified adjusted gross income above $109,000 and married couples filing jointly with income above $218,000 can owe an additional income-related monthly adjustment amount, commonly known as IRMAA, for Part B and Part D.

These surcharges can catch newly retired households because Medicare generally relies on tax information from an earlier year. A person who had a high salary before retirement may therefore receive an IRMAA determination even after current income has fallen substantially. Retirement, reduced work hours, marriage, divorce and the death of a spouse are among the life-changing events that may permit someone to request a new determination using Form SSA-44.

This is another example of why Medicare planning overlaps with tax planning. Roth conversions, investment gains and large retirement-account withdrawals can increase modified adjusted gross income and potentially push retirees into higher Medicare premium brackets. Those transactions may still make excellent long-term financial sense, but the Medicare impact should be included before the decision is made.

Prescription Coverage Has Its Own Trap

Retirees also need to pay close attention to prescription drug coverage. Someone who goes 63 consecutive days or more after the end of the Medicare Part D Initial Enrollment Period without Part D or other creditable prescription coverage may face a late-enrollment penalty. That penalty generally remains attached to the person’s Part D premium for as long as Medicare drug coverage continues.

The issue can become especially important when someone leaves an employer plan or relies primarily on another health system, including certain veterans who receive care through the VA. Whether existing prescription coverage is considered creditable should be confirmed rather than assumed. Medicare decisions should also be coordinated before employer coverage is dropped because voluntarily abandoning coverage can create consequences that are difficult to reverse.

Compare Benefits, Not Insurance Company Logos

Brand recognition can provide some comfort, but the name of a national insurer should not determine the decision by itself. Medicare Advantage networks and benefits can vary by county and even between plans offered by the same company. Medigap benefits, meanwhile, are standardized by letter in most states, meaning a Plan G from one insurer provides the same basic standardized benefits as Plan G from another, although premiums, pricing methods, service and future rate increases can differ.

Consumers should therefore compare the actual policy rather than assuming a larger carrier automatically provides the best value. For Medicare Advantage, that means examining doctors, hospitals, drug formularies, out-of-pocket limits, prior authorization requirements and supplemental benefits. For Medigap, it means comparing premiums, pricing history and insurer characteristics while remembering that the underlying standardized benefits for the same letter plan are largely identical.

The same scrutiny should apply to popular extras such as dental coverage, fitness memberships or Part B givebacks. Those benefits can be valuable, but they should not overshadow access to physicians or exposure to thousands of dollars of medical cost sharing. Insurance exists primarily to protect against expensive events, not to maximize the number of small perks someone receives while healthy.

Choosing Medicare is ultimately an exercise in deciding which risks a retiree is willing to keep and which risks should be transferred to an insurer. A lower monthly premium can be attractive, particularly for someone living on a fixed income, but premium savings should be weighed against provider restrictions, prior authorization and potential out-of-pocket expenses. Higher-premium coverage can also be wasteful if it provides protections a particular retiree does not value.

The right Medicare option is therefore not universally Medicare Advantage or universally Original Medicare with Medigap. It is the arrangement that fits the person’s doctors, medications, travel habits, financial resources and tolerance for uncertainty. The mistake is believing that the cheapest premium automatically produces the cheapest—or best—health care.
