Federal Employees Health Benefits Program (FEHBP) 2026

The Federal Employees Health Benefits Program (FEHBP) is the largest employer-sponsored health insurance program in the United States. Established in 1960 and administered by the U.S. Office of Personnel Management (OPM), it provides comprehensive health coverage to federal employees, retirees, and their eligible family members through a wide selection of private health plans.

Who Is Eligible

FEHBP coverage is available to:

  • Active federal civilian employees (including many postal workers under related rules)
  • Retired federal employees (annuitants) and their eligible family members
  • Survivors of federal employees or annuitants
  • Certain former spouses under specific court-ordered or statutory eligibility rules

Eligibility and enrollment rules are set by federal law and OPM regulations. New employees generally have a limited window after hiring to enroll, while most changes occur during the annual Open Season or after qualifying life events.

Types of Plans Available

FEHBP offers a broad range of plan options so participants can select coverage that matches their location, health needs, and budget. Common plan types include:

  • Fee-for-service (FFS) plans, often with a preferred provider organization (PPO) network
  • Health Maintenance Organization (HMO) plans, which typically require use of network providers
  • High Deductible Health Plans (HDHPs) that can be paired with a Health Savings Account (HSA)
  • Consumer-driven health plans and other variations

Nationwide plans are available alongside regional or local options. Coverage generally includes preventive care, hospital and physician services, prescription drugs, mental health and substance use treatment, maternity care, and other standard benefits. Specific covered services, networks, deductibles, copayments, and coinsurance vary by plan.

Premiums and Cost Sharing

Premiums are shared between the enrollee and the federal government. The government contribution is set by formula and typically covers a substantial portion of the total premium. Enrollees pay the remainder through payroll or annuity deductions. Costs differ significantly by plan, coverage tier (Self Only, Self Plus One, or Self and Family), and geographic area.

High-deductible options usually feature lower premiums in exchange for higher out-of-pocket costs before coverage begins. Traditional plans often have higher premiums but lower deductibles and more predictable cost sharing.

Annual Open Season and Enrollment Changes

The main opportunity to enroll or change coverage is the annual Federal Benefits Open Season, which generally runs from mid-November to mid-December. During this period, eligible individuals may:

  • Enroll in a plan for the first time
  • Switch plans or options
  • Change coverage tiers
  • Cancel coverage

Changes typically become effective on January 1 of the following year. Outside Open Season, enrollment or plan changes are usually limited to qualifying life events such as marriage, birth or adoption of a child, or loss of other coverage.

Coordination with Medicare

Many federal retirees become eligible for Medicare at age 65. FEHBP plans coordinate with Medicare Parts A and B. In most cases Medicare becomes the primary payer and the FEHBP plan provides secondary coverage, which can significantly reduce out-of-pocket costs. Some plans also offer prescription drug coverage designed to work with or as an alternative to Medicare Part D through Employer Group Waiver Plan (EGWP) arrangements.

Retirees should carefully review how their chosen FEHBP plan interacts with Medicare to avoid gaps or unnecessary expenses.

Postal Service Health Benefits (PSHB) Program

A separate but related program, the Postal Service Health Benefits (PSHB) Program, now serves U.S. Postal Service employees, retirees, and their families. While many features parallel FEHBP, PSHB has its own plan offerings, enrollment rules, and certain Medicare-related requirements for annuitants. Enrollment and plan comparison for PSHB are also managed through OPM systems.

Practical Tips for Choosing and Using Coverage

  • Compare plans annually during Open Season using the official tools on OPM.gov. Review premiums, deductibles, provider networks, prescription formularies, and out-of-pocket maximums.
  • Verify that preferred doctors, hospitals, and pharmacies participate in the plan’s network, especially with HMO options.
  • Consider an HDHP paired with an HSA if you are relatively healthy and want lower premiums plus tax-advantaged savings for medical expenses.
  • Review mental health, maternity, and prescription benefits carefully if these are important to you or your family.
  • If you are approaching Medicare eligibility or already enrolled, examine coordination rules and any Medicare Part D implications.
  • Keep documentation of qualifying life events if you need to make mid-year changes.

Summary

The Federal Employees Health Benefits Program gives federal employees, retirees, and their families access to a competitive marketplace of private health plans with substantial government premium contributions. Plan choices range from traditional fee-for-service and HMO options to high-deductible plans that work with health savings accounts. Annual Open Season provides the primary opportunity to select or change coverage, while coordination with Medicare is an important consideration for retirees. Using official OPM comparison tools and reviewing network and benefit details helps participants select coverage that fits their health needs and financial situation.
