Managing Medicare Out-of-Pocket Costs

Medicare covers only 60% of total health-care costs for Americans age 65 and older.1 Deductibles, copays, coinsurance, and payments for services not covered by Medicare can result in substantial out-of-pocket expenses. And there is no annual or lifetime out-of-pocket limit.

Whether you are already enrolled in Medicare or planning to enroll in the future, you may want to consider two options to help manage out-of-pocket costs: Medigap and Medicare Advantage. Both are offered by private insurance companies approved and regulated by Medicare. They are mutually exclusive — you cannot be covered by both — but either might provide more stability to your health-care spending in retirement.

Supplemental Insurance

Medigap supplements coverage under Original Medicare Part A (hospital insurance) and Part B (medical insurance), and you must be enrolled in Part A and Part B in order to buy a Medigap policy. These policies pay nearly all or a percentage of Medicare out-of-pocket costs such as deductibles, copays, and coinsurance. Some plans may pay for services not covered by Medicare, such as emergency medical care outside the United States (up to plan limits), but they generally do not cover long-term care, vision or dental care, hearing aids, or private-duty nursing. New Medigap policies do not cover prescription drugs, so you must enroll in Medicare Part D if you want prescription drug coverage.

You can enroll in a Medigap plan at any time, but the best time to do so is during the initial Medigap open enrollment period — the six-month period that begins on the first day of the month in which you are 65 or older and enrolled in Medicare Part B. During this time, you can buy any Medigap policy in your state for the same premium the insurance company charges to healthy enrollees, even if you have health problems. If you miss this opportunity, a company can charge you more for coverage or refuse coverage altogether, depending on your health. Medigap policies are guaranteed renewable; once you are enrolled, you cannot be denied coverage or charged more than healthy enrollees due to changes in your health, as long as you pay your premium.

A Medigap policy covers only one individual, so you and your spouse need separate policies if you both want coverage.

Saving for Retirement Health Care

This chart shows the savings that a man, a woman, and a couple who retired at age 65 in 2022 might need to meet retirement health-care expenses, assuming median prescription drug expenses. Medicare Advantage Plans can reduce out-of-pocket expenses, but they often have limited networks and may require approval to cover certain medications and services.

Savings required by a Man: Original Medicare - $166,000; Medicare Advantage average usage - $96,000; Medicare Advantage high usage - $134,000. Woman: Original Medicare - $197,000; Medicare Advantage average usage - $113,000; Medicare Advantage high usage - $184,000. Couple: Original Medicare - $318,000; Medicare Advantage average usage - $184,000; Medicare Advantage high usage - $256,000.Source: Employee Benefit Research Institute, 2023. Projections are based on a 90% chance of meeting expenses and assume savings earn a return of 7.32% from age 65 until expenditures are made. Does not include vision, hearing, dental, or long-term care expenses. Original Medicare estimate includes premiums for Medicare Parts B and D, the Part B deductible, out-of-pocket prescription drug spending, and premiums for Medigap Plan G, which would pay most other out-of-pocket costs. Some Medicare Advantage Plans require additional premiums, which are not included.

All-in-One Coverage

Medicare Advantage (MA) Plans, also called Medicare Part C, replace Original Medicare Part A and Part B and often offer prescription drug coverage, similar to Medicare Part D. Benefits are provided through a private insurance company, but much of the funding comes from the federal government, and plans must offer the same benefits as Original Medicare.

MA plans generally encourage the use of network providers and have higher costs for out-of-network services. They may offer additional benefits not covered by Original Medicare, such as dental care, eyeglasses, and wellness programs. You will typically pay your Medicare Part B premium and may pay an additional premium, depending on the plan. You may also have out-of-pocket deductibles, copays, and coinsurance. However, all MA plans have an annual out-of-pocket maximum.

You can enroll in an MA plan instead of Original Medicare during your initial Medicare enrollment period.2 You can change coverage from Original Medicare to MA or vice versa, or change between MA plans, during the Medicare Open Enrollment period from October 15 to December 7. You can change from MA to Original Medicare or switch MA plans during the Medicare Advantage Open Enrollment period from January 1 to March 31. You may also be able to make changes during other special enrollment periods.
