The Medicare Cost Trap That Can Undermine a Fixed Budget

Medicare serves as an important backstop for medical expenses, but paying monthly premiums does not mean all health care costs disappear.

In reality, total Medicare spending goes far beyond the premium, and many retirees are caught off guard by the added bills. Knowing what Medicare covers, and what you may still owe, can help you plan ahead for retirement expenses.

Don’t budget for the premium alone

The standard Medicare Part B premium is only one recurring expense tied to coverage. If you plan for just that amount, you may leave yourself exposed financially.

Other charges can still apply. You may need to meet a deductible before Medicare begins paying for certain care. After that, copays and coinsurance can still come into play. A copay is a set amount for covered services such as a primary care appointment or prescription drugs, while coinsurance is a percentage of the service cost that you must pay yourself.

Premiums themselves can also rise over time because of inflation and other factors. Since insurance costs are not static, it makes sense to leave room in your budget for modest increases from year to year.

Overlooked expenses

Part B is not the only cost to account for. There are also Part D prescription drug premiums, which you must pay each month to keep that coverage. In addition, Medicare generally does not pay for routine dental, vision, or hearing care.

Some retirees choose Medigap coverage to help offset out-of-pocket costs such as deductibles, copays, and coinsurance. If you decide to add that type of supplemental policy, it should also be included in your budget.

How to avoid the surprise on a fixed income

Many retirees rely on Social Security and portfolio withdrawals for income, which means their finances are largely fixed. Because Medicare is a major expense, it helps to include both premiums and an extra monthly buffer for costs beyond the premium when estimating retirement spending.

It is also smart to review your plan each year to check for changes in coverage, premiums, provider networks, and covered drugs. And be sure to enroll on time, since signing up late can trigger a 10% penalty on top of your Part B premium. That fee increases for each full 12-month period you were eligible for Part B but did not enroll. Part D has similar late-enrollment penalties.

Planning for the full cost of health care can make retirement much easier to manage. Rather than treating Medicare as a single deduction from Social Security, it may be better to think of it as a broader household expense.
