PSHB vs FEHB: What Changed for Postal Employees and Retirees

If you're a USPS employee or retiree still looking for your health plan under FEHB, you won't find it. The Postal Service Reform Act of 2022 created the Postal Service Health Benefits Program, and as of January 1, 2025, every postal employee, annuitant, and eligible family member was moved out of FEHB and into PSHB. The transition is complete — there's no opt-out, no grandfathering, and no path back to FEHB.

The confusion is understandable. FEHB ran the postal health benefits system for decades, and plenty of retirement guides written before 2025 still reference it as the active program. Any checklist that mentions selecting an FEHB plan for postal retirement is now obsolete.

The Structural Differences

Program exclusivity. PSHB is the only health benefits program available to the Postal Service. General federal employees on the GS pay scale remain in FEHB. The two programs operate under separate carrier contracts, separate risk pools, and separate premium calculations.

Plan year alignment. Under FEHB, the active employee plan year aligned with the first day of the first full pay period in January. PSHB runs on a strict calendar year — January 1 through December 31 — for both active employees and retirees. This matters for premium timing and Open Season decisions.

Medicare Part B mandate. This is the single largest difference, and it affects every postal annuitant approaching age 65. Under PSHB, postal retirees who become entitled to Medicare Part A must also enroll in Medicare Part B to keep their PSHB coverage. FEHB had no such requirement — federal retirees under FEHB can decline Part B without losing their health plan.

If you're a postal retiree subject to the mandate and you fail to enroll in Part B — or later drop it — OPM will terminate your PSHB coverage. That termination is permanent. There's no reinstatement mechanism.

Integrated Part D prescription coverage. All PSHB plans must provide prescription drug coverage to Medicare-eligible retirees through an integrated Employer Group Waiver Plan under Medicare Part D. Enrollment is automatic once OPM confirms your Medicare eligibility. If you opt out of the integrated Part D benefit, you lose all prescription drug coverage under your PSHB plan.

Who's Exempt from the Part B Mandate

Five narrow exceptions exist:

1. Pre-2025 retirees who retired on or before December 31, 2024, and weren't enrolled in Part B as of January 1, 2025
2. Active employees who turned 64 on or before January 1, 2025 (born on or before January 1, 1961)
3. Overseas residents living permanently outside the United States and its territories
4. VA health beneficiaries enrolled in or eligible for VA healthcare under 38 U.S.C. Chapter 17
5. Indian Health Service beneficiaries eligible for IHS health services

If a primary annuitant qualifies for one of these exceptions, their covered family members are also exempt. OPM verifies exemptions automatically through its databases — no manual filing is needed for the first two categories.

Premium Comparison: 2026 Numbers

Both FEHB and PSHB premiums rose in 2026. PSHB premiums increased by an average of 11.3%, compared to 12.3% for FEHB. The programs have different carrier pools and risk profiles, so direct plan-to-plan comparisons aren't meaningful, but the overall cost trajectory is roughly parallel.

In 2026, PSHB enrollees have 75 plan options across 17 health carriers. The geographic spread of regional HMO options has expanded since the program's first year, giving retirees more choices in metropolitan areas.

For retirees subject to the Medicare Part B mandate, the 2026 standard Part B premium is $202.90 per month. High-income retirees pay more through the Income-Related Monthly Adjustment Amount, based on their Modified Adjusted Gross Income from two years prior. At the highest IRMAA bracket (individual MAGI above $500,000), the monthly Part B premium reaches $689.90.

How Premiums Are Paid Differently After Retirement

As an active postal employee, your health insurance premiums are deducted pre-tax from each paycheck through premium conversion. After retirement, premiums shift to post-tax deductions from your monthly OPM annuity payment.

During the OPM adjudication period — which averaged 108 days for all claims and 96 days for digital submissions as of June 2026 — your PSHB premium deductions are temporarily suspended. OPM deducts retroactive premiums from your adjustment payment once your case is finalized. Your coverage isn't interrupted during this period, but you need to account for the catch-up deduction in your financial planning.

Open Season and Plan Changes

PSHB Open Season runs from the second Monday in November through the second Monday in December each year. Plan selection and changes are handled through OPM's PSHB enrollment portal, which requires a Login.gov account.

If you don't make a change during Open Season, your current PSHB enrollment continues at the updated premium. If your plan exits the program or stops serving your area, OPM automatically transitions you to a comparable plan. For retirees whose monthly annuity payment is too small to cover PSHB premiums, direct premium payments can be made to the National Finance Center.

What This Means for Your Retirement Planning

If you're planning a USPS retirement in 2026 or beyond, your health benefits will be entirely under PSHB. The key decision points are understanding whether you'll face the Medicare Part B mandate, budgeting for the additional Part B premium if you will, and selecting the right PSHB plan during Open Season.

The USPS Retirement Guide covers the full PSHB coordination sequence, including the Medicare enrollment windows, the five exceptions in detail, and how to manage health coverage during the interim pay period after separation.
