As federal employees and retirees approach Medicare eligibility, it’s common to feel uncertain about how it will affect existing Federal Employees Health Benefits (FEHB) coverage. Many assume Medicare replaces FEHB, but in most cases, the two programs work together. Understanding how Medicare and FEHB coordinate can help you make more confident healthcare decisions as you transition into retirement.
Medicare is the federal health insurance program primarily for individuals age 65 and older, though some qualify earlier due to disability or certain medical conditions. Medicare coverage is divided into several parts. Part A covers inpatient hospital care and is often available without a premium. Part B covers medical services and outpatient care and requires a monthly premium. Part D provides prescription drug coverage through private plans. Medicare Advantage plans (Part C) are private plans that combine Parts A and B and often include prescription drug coverage and additional benefits.
FEHB coverage continues to play an important role even after Medicare eligibility. Rather than replacing FEHB, Medicare typically becomes the primary payer, with FEHB acting as secondary coverage. Many FEHB plans coordinate benefits by reducing or waiving deductibles, copayments, and coinsurance when Medicare pays first. This coordination can significantly lower out-of-pocket healthcare costs in retirement, particularly for those who anticipate higher medical usage.
Enrollment options vary depending on the type of Medicare coverage you choose. Medicare Parts A and B are enrolled through the Social Security Administration, while some Medicare drug benefits and Medicare Advantage plans may be accessed directly through FEHB plans. Once you enroll in Medicare, it’s important to notify your FEHB plan so benefits are coordinated correctly.
Becoming eligible for Medicare is also considered a qualifying life event (QLE), allowing a one-time opportunity to make changes to FEHB coverage outside of the annual Open Season. This may include switching FEHB plans, adjusting coverage options, or reassessing whether your current plan still meets your needs once Medicare becomes primary. Some retirees also explore suspending FEHB coverage when enrolling in certain Medicare Advantage plans. While FEHB coverage can be suspended and later reinstated, canceling FEHB coverage as an annuitant is permanent and should be carefully considered.
Cost is another key factor. Enrolling in Medicare does not affect your FEHB premiums, though Medicare premiums may be higher for individuals with higher incomes. Most beneficiaries receive a government subsidy toward Part B premiums, with that subsidy decreasing as income increases. Additionally, once enrolled in Medicare, individuals can no longer contribute to a Health Savings Account and must stop contributions in advance to avoid tax penalties.
Ultimately, the decision to enroll in Medicare is highly personal. Reviewing how Medicare and FEHB work together can help ensure your healthcare coverage aligns with both your financial plan and your retirement goals.
