Understanding enrollment periods, eligibility, and plan coordination is crucial for making the most of Medicare and FEHB.
Why Pairing Medicare with FEHB Makes Sense
As a federal employee or retiree, you enjoy one of the most robust health insurance programs available through the Federal Employees Health Benefits (FEHB) program. Yet, many federal workers are discovering the advantages of adding Medicare to their healthcare strategy. With Medicare’s distinct benefits, combining it with FEHB can offer you enhanced coverage, lower out-of-pocket expenses, and peace of mind.
Let’s explore why this growing trend might be the right move for you.

Filling Coverage Gaps
Medicare Parts A and B cover hospital and medical services that might come with higher out-of-pocket costs under FEHB alone. For instance:
-
Part A (Hospital Insurance): Covers inpatient stays, skilled nursing facility care, and hospice care, often with no premium for most federal workers.
-
Part B (Medical Insurance): Includes outpatient services, preventive care, and durable medical equipment, reducing potential costs for frequent doctor visits or treatments.
When Medicare pays first, FEHB acts as secondary insurance, picking up costs Medicare doesn’t cover, such as coinsurance and deductibles.
Reducing Your Out-of-Pocket Costs
While FEHB offers comprehensive benefits, retirees can face rising premiums and copayments. Medicare can help mitigate these expenses, especially with the introduction of the $2,000 annual out-of-pocket drug cost cap for Medicare Part D in 2025.
When You Should Enroll in Medicare
Timing is everything. Federal employees and retirees need to understand when and how to enroll in Medicare to maximize benefits.
Initial Enrollment Period (IEP)
Your IEP spans seven months: three months before your 65th birthday, your birth month, and three months after. Enrolling during this period ensures coverage begins seamlessly.
Special Enrollment Period (SEP)
If you’re still working past 65 and covered under FEHB, you can delay enrolling in Medicare Part B without penalties. You’ll qualify for an SEP to enroll in Part B once you retire or lose FEHB coverage.
Avoiding Late Enrollment Penalties
Failing to enroll in Medicare Part B during your IEP or SEP can result in lifetime penalties, increasing your monthly premium. Plan ahead to avoid unnecessary costs.
Coordinating Benefits: Medicare as Primary or Secondary Payer
Understanding which insurance pays first is crucial for avoiding claim denials and maximizing benefits. Here’s how it typically works:
Medicare as Primary Payer
If you’re retired and enrolled in both Medicare and FEHB, Medicare generally pays first. FEHB acts as your secondary insurance, covering any remaining costs Medicare doesn’t pay.
FEHB as Primary Payer
For active employees aged 65 and older, FEHB usually remains your primary insurance. Medicare provides secondary coverage, filling in gaps left by FEHB.
Balancing Costs
When deciding whether to keep both FEHB and Medicare, weigh the combined costs of premiums, copayments, and potential out-of-pocket expenses. Retaining both often provides a safety net, but it’s essential to evaluate your specific needs.
Medicare Part D and Prescription Drug Coverage
Medicare Part D offers prescription drug coverage, but most FEHB plans already include robust pharmacy benefits. Should you enroll in Part D?
FEHB vs. Part D
If your FEHB plan provides adequate drug coverage, you may not need Part D. However, for retirees with high medication costs, enrolling in Part D might be beneficial due to its new $2,000 out-of-pocket cap.
EGWP Integration
Many FEHB plans coordinate with Medicare through Employer Group Waiver Plans (EGWPs), ensuring seamless prescription coverage without requiring standalone Part D enrollment.
Advantages of Combining Medicare and FEHB
Comprehensive Coverage
By combining Medicare and FEHB, you’ll enjoy broader coverage, including:
-
Lower deductibles and copayments.
-
Enhanced hospital and outpatient care.
-
Greater access to specialized treatments and providers.
Financial Protection
Medicare’s new prescription drug cap offers significant savings, while FEHB’s secondary coverage helps limit unexpected medical expenses.
Nationwide Access
With Medicare, you gain nationwide provider access, making it ideal for retirees who travel frequently or move between states. FEHB plans often have restricted networks, so Medicare expands your options.
Costs and Savings: What You Need to Know
While Medicare offers valuable benefits, it’s essential to understand the associated costs:
Medicare Part A
-
Most federal employees qualify for premium-free Part A based on their work history.
-
In 2025, the inpatient hospital deductible is $1,676 per benefit period.
Medicare Part B
-
The standard monthly premium in 2025 is $185, with an annual deductible of $257.
-
Higher-income earners pay more under the Income-Related Monthly Adjustment Amount (IRMAA).
FEHB Premiums
-
FEHB premiums have increased by an average of 11.2% in 2025, making Medicare’s cost-saving potential more attractive.
Coordinating Savings
By enrolling in Medicare, you may reduce your reliance on FEHB, potentially choosing a less expensive plan during Open Season to offset additional Medicare costs.
Navigating Enrollment Periods and Changes
Understanding key enrollment periods helps you maintain seamless coverage:
Open Season
During Open Season (October 15 to December 7), you can:
-
Enroll in Medicare Advantage (Part C) if desired.
-
Switch between Original Medicare and FEHB.
-
Adjust Part D plans for prescription coverage.
Qualifying Life Events (QLEs)
Outside Open Season, QLEs—such as retirement or relocation—may allow you to make changes to your FEHB or Medicare coverage.
Making Informed Choices
The decision to combine Medicare and FEHB depends on your health needs, financial situation, and retirement plans. To determine the best approach:
Evaluate Your Health Needs
-
Do you anticipate high medical expenses or frequent doctor visits?
-
Will you require specialized treatments not covered fully by FEHB?
Assess Financial Implications
-
Compare Medicare premiums, deductibles, and copayments with your current FEHB costs.
-
Factor in Medicare’s out-of-pocket caps for added financial protection.
Seek Guidance
Consulting with a benefits advisor or using resources like the Office of Personnel Management’s (OPM) tools can clarify your options and ensure a smooth transition.
Enhancing Your Healthcare Strategy in 2025
Combining Medicare and FEHB in 2025 provides you with a strategic approach to healthcare in retirement. With rising healthcare costs, leveraging both systems can optimize your coverage, reduce financial strain, and ensure access to the care you need.
Whether you’re nearing retirement or evaluating options as a current retiree, now is the time to review your health plan and take advantage of Medicare’s expanded benefits. By understanding the interplay between Medicare and FEHB, you’re setting yourself up for a secure and worry-free retirement.
