Key Takeaways

• PSHB and FEHB differ in cost structures, eligibility, and Medicare interaction beginning in 2025 and 2026.
• Comparing premiums and out-of-pocket costs can help you select the right health benefits for your situation.

Major health benefit changes began in 2025 with the launch of the Postal Service Health Benefits (PSHB) Program, affecting USPS employees and retirees. If you’re comparing PSHB to the Federal Employees Health Benefits (FEHB) Program, it’s important to understand premiums, out-of-pocket costs, and how Medicare affects your coverage in 2026.

What Is the PSHB Program?

Origins and launch in 2025

The Postal Service Health Benefits (PSHB) Program was created as a separate part of the federal health benefits ecosystem through the Postal Service Reform Act of 2022. The intent was to provide USPS employees, annuitants, and eligible family members with a specialized health benefits program, administered by the U.S. Office of Personnel Management (OPM). Official enrollment began in the fall of 2024, and PSHB coverage officially started on January 1, 2025. This transition marked a new era for postal employees, moving their health benefits out of the general FEHB pool into a tailored program with its own structure and rules.

Key features of PSHB plans

PSHB plans closely mirror many parts of FEHB but are designed specifically for the postal workforce. Some features include:

• Separate plan options exclusively for Postal Service employees and annuitants
• Coordination with Medicare Part B enrollment for retirees starting in 2025
• OPM administration, ensuring regulatory oversight and consistency
• No required change to provider networks for most enrollees, maintaining continuity of care for many
• Annual Open Season for changes and new enrollments, similar to FEHB

How Does FEHB Work in 2026?

Overview of FEHB basics

The Federal Employees Health Benefits (FEHB) Program is one of the largest employer-sponsored health insurance plans in the U.S. It provides federal employees, retirees, and eligible family members access to a variety of private health plans. Members pay part of the premium, with the government covering the balance. Coverage and plan types are broad, offering options ranging from fee-for-service to health maintenance organizations.

Who is eligible for FEHB now?

In 2026, most current federal and postal employees who are not part of PSHB, and many federal retirees, remain eligible for FEHB coverage. Eligibility typically requires current or past employment with a federal agency and meeting specific hour and duration requirements. However, after the 2025 transition, most USPS employees and their eligible family members are no longer in FEHB, but instead in PSHB, unless they are eligible under specific exceptions recognized by OPM.

What Are Out-of-Pocket Costs?

Terms: deductibles, copays, coinsurance

Out-of-pocket costs are amounts you pay directly to health care providers when you use services, above and beyond your premium. The most common terms are:

• Deductible: The amount you pay annually before your health plan starts covering certain services.
• Copay: A flat fee you pay for office visits, prescriptions, or other services.
• Coinsurance: A percentage of the cost you pay for medical services, with your plan covering the rest—often after your deductible is met.

Typical out-of-pocket ranges

For both PSHB and FEHB plans, out-of-pocket expenses can range significantly based on:

• The specific plan you choose
• Your usage of medical services
• Whether you use in-network or out-of-network providers

Annual deductibles often range from less than $500 to just over $2,000 for families, with annual maximums (out-of-pocket caps) providing a safety net. Copays might range from $10 to $50 for office visits, with coinsurance rates often set between 10% and 30% for various services. It’s important to separately consider deductibles and out-of-pocket maximums, as these figures can impact your annual costs greatly.

PSHB vs FEHB: Premium Rate Differences

How rates are set for each program

Premium rates in both PSHB and FEHB are set based on total plan costs and the government’s share, recalculated each year. For PSHB, premiums are negotiated separately from FEHB and reflect only postal employee enrollment, while FEHB premiums are pooled across all participating federal workers and retirees. OPM negotiates and publishes rates annually for each program during Open Season.

What factors influence premium changes?

Several factors can affect premium changes, including:

• Changes in medical costs and prescription drug pricing
• The collective health experience of the plan’s covered population
• Changes in plan design or coverage
• Administrative costs for each program
• Required Medicare Part B enrollment for PSHB annuitants and survivors (beginning in 2025)

Since PSHB and FEHB are now separate risk pools, their premium trajectories may differ slightly over time. Your specific cost will depend on plan choice, coverage tier (self, self plus one, or family), and whether you’re actively employed or retired.

Which Program Usually Has Lower Employee Costs?

Cost structures for active employees

For active USPS employees, the PSHB and legacy FEHB cost-sharing formulas are similar. Employees continue to pay part of the total premium (with USPS covering the majority), and out-of-pocket costs are largely plan-specific. Because PSHB plans serve only postal workers and reflect a separate risk pool, premium changes may diverge over time, but employees should not expect dramatic cost shifts in the initial years, barring other federal benefits adjustments.

Retiree cost considerations

PSHB introduces a major shift for retirees and certain family members: once eligible for Medicare Part A (typically age 65+), most must enroll in Medicare Part B as a condition for PSHB coverage. This represents a new monthly cost for many, but PSHB premiums themselves may be adjusted to reflect lower health expenses due to the intersection with Medicare paying primary for many services. This can mean lower plan premiums but higher total monthly costs when factoring in Medicare B premiums. FEHB retirees, by contrast, are generally not required to enroll in Medicare Part B but may do so for expanded coverage coordination.

How Do Medicare and PSHB Interact?

Required Medicare enrollment rules

A key feature of the new PSHB Program is the requirement for most eligible annuitants and survivors to enroll in Medicare Part B upon reaching eligibility. This began with the 2025 transition. While there are specific exceptions (such as foreign residency), most postal retirees now need both PSHB and Medicare Part B for full coverage. This rule was introduced to coordinate federal and Medicare benefits more efficiently, and to reduce premium costs for the overall group.

Impact on premiums and OOP costs

When you have both PSHB and Medicare Part B, Medicare typically pays first on covered medical services, with PSHB covering what’s left. This may reduce your out-of-pocket exposure for many services, though you also pay the separate Medicare Part B premium each month. For some, especially those with frequent healthcare usage, this combined coverage results in improved cost certainty and lower annual risks. It’s important to compare not just premiums, but the full range of expected expenses—including monthly premiums and out-of-pocket maximums—when budgeting for retirement.

What Questions Should Employees Ask?

Understanding your coverage needs

Before choosing between PSHB and (where applicable) FEHB plans, ask yourself:

• How often do you use medical services?
• Are your preferred providers in the plan networks?
• What is your anticipated prescription needs?
• Are you (or a dependent) approaching Medicare eligibility?

Tips for reviewing program options

• Carefully review both premiums and all out-of-pocket estimates for each plan
• Consider how Medicare enrollment will impact your overall costs and provider choices
• Use OPM’s available plan comparison tools during Open Season
• Re-examine your needs annually, as premiums and plan designs can change

Assessing your health coverage options can feel overwhelming, especially with recent program updates. Take time to review your own needs, understand how premiums and out-of-pocket costs work, and plan ahead, especially as Medicare enrollment ties in with USPS retirement.
