Federal Employees Health Benefits (FEHB) can be used alongside Medicare, and retirees often maintain both to minimize out-of-pocket healthcare costs.
When a retiree is enrolled in both FEHB and Medicare, Medicare typically acts as the primary payer for Part A and Part B services.
FEHB plans generally offer prescription drug coverage that is considered creditable, meaning it is as good as or better than standard Medicare Part D.
Federal employees have access to one of the most robust employer-sponsored health insurance programs in the country — and understanding how to use it fully can make a meaningful difference in your healthcare costs, especially as you approach or enter retirement. The Federal Employees Health Benefits (FEHB) program, managed by the U.S. Office of Personnel Management (OPM), serves current and retired federal workers as well as their eligible family members. With dozens of competing plans to choose from — spanning everything from traditional fee-for-service options to HMOs and high-deductible plans — FEHB offers a level of flexibility that most private-sector employees can only dream about.
What sets the FEHB program apart is the breadth of its offerings and the government's substantial role in sharing premium costs. Here's what federal employees can expect from their coverage:
Each fall, federal employees get a valuable window to revisit their healthcare decisions during FEHB Open Season. This annual period — typically running from mid-November through mid-December — allows employees to switch plans, add or remove dependents, or enroll for the first time. Outside of Open Season, qualifying life events such as marriage, the birth of a child, adoption, or a significant change in employment status can trigger a Special Enrollment Period, providing additional flexibility when life doesn't follow a tidy schedule.
It's worth stepping back to appreciate just how significant FEHB coverage really is for federal workers and their families:
The Federal Employees Health Benefits program is more than just a workplace perk — it's a cornerstone of financial security for the millions of people who dedicate their careers to public service. With a wide selection of plans, meaningful government contributions, and the ability to maintain coverage well into retirement, FEHB provides a powerful foundation for managing healthcare needs at every stage of life. Taking the time to compare plan options each Open Season and understanding how FEHB interacts with Medicare in retirement can help federal employees and retirees get the most from this exceptional benefit.
