Key Takeaways
-
In 2025, new eligibility requirements for the Postal Service Health Benefits (PSHB) Program could impact your ability to maintain coverage, especially if you’re a retiree or nearing retirement.
-
Exceptions to Medicare Part B enrollment and transitioning from FEHB to PSHB involve critical deadlines, status checks, and careful review of your annuitant classification.
Understanding the 2025 PSHB Landscape
The shift from the Federal Employees Health Benefits (FEHB) Program to the Postal Service Health Benefits (PSHB) Program is one of the most significant changes affecting Postal Service employees and retirees in recent years. As of January 1, 2025, all USPS employees and annuitants must enroll in a PSHB plan to continue health coverage. However, your eligibility—and how it interacts with Medicare—depends on multiple variables you may not be aware of until it’s too late.
You need to know these eligibility rules before you sign or enroll in anything. They’re not as straightforward as you might think.
Who Is Required to Enroll in a PSHB Plan in 2025?
Most current USPS employees and annuitants are required to switch to a PSHB plan beginning in 2025. This applies to:
-
Career USPS employees enrolled in FEHB in 2024
-
USPS annuitants and survivors who receive an annuity and had FEHB coverage prior to 2025
-
Medicare-eligible annuitants and family members who meet certain age and retirement timelines
Enrollment into PSHB is not automatic for everyone. While active employees will typically be auto-enrolled into a comparable PSHB plan during Open Season, retirees and survivors need to pay closer attention to ensure their coverage continues without interruption.
Medicare Part B Requirements You Can’t Ignore
Starting in 2025, Medicare-eligible annuitants and eligible family members must also enroll in Medicare Part B in order to maintain their PSHB coverage. Failing to do so could result in the loss of certain benefits or drug coverage.
You are required to enroll in Medicare Part B if:
-
You are a USPS annuitant or family member who is Medicare-eligible as of January 1, 2025, or become Medicare-eligible after that date
-
You are not exempt under the limited categories defined by the Office of Personnel Management (OPM)
Who Is Exempt from the Part B Requirement?
Not everyone needs to sign up for Medicare Part B. The following individuals are exempt from the mandate:
-
Those who retired on or before January 1, 2025, and are not enrolled in Part B
-
Employees who are 64 or older as of January 1, 2025
-
Annuitants and family members living overseas
-
Those receiving care through the Veterans Health Administration or Indian Health Service
Even if you’re exempt, you still have the option to enroll in Medicare Part B and coordinate it with your PSHB plan to potentially reduce your out-of-pocket costs.
The Transition From FEHB to PSHB: What You Need to Do
For most current FEHB participants within USPS, the transition to PSHB is designed to be automatic, but it still requires action in certain cases:
-
Employees: You’ll be auto-enrolled in a similar PSHB plan unless you make changes during Open Season.
-
Annuitants: If you don’t actively enroll in a PSHB plan during Open Season, your FEHB coverage will not carry over. That means you must take action to ensure uninterrupted coverage.
Open Season for 2025 coverage ran from November to December 2024. If you missed that window, you may only enroll during a Qualifying Life Event (QLE), such as marriage, divorce, or loss of other coverage.
Your Drug Coverage Also Changes in 2025
With the implementation of PSHB, prescription drug benefits for Medicare-eligible annuitants and family members are now provided through a Medicare Part D Employer Group Waiver Plan (EGWP). This plan is automatically included in your PSHB coverage if you’re eligible.
But there’s a catch: if you choose to opt out of this drug coverage, you’ll lose drug benefits under PSHB altogether. Re-enrollment is not guaranteed and may only happen during future Open Seasons.
Timelines That Matter More Than You Think
There are specific dates and age cutoffs that define your eligibility and responsibilities:
-
April to September 2024: Special Enrollment Period (SEP) for Medicare Part B ran for eligible annuitants to avoid penalties
-
November to December 2024: Open Season enrollment window for PSHB
-
January 1, 2025: Official transition date to PSHB plans for all USPS employees and annuitants
-
Throughout 2025 and beyond: QLEs remain the only opportunity to change your PSHB plan outside of Open Season
If you missed any of the 2024 enrollment periods, it’s critical to explore QLE options or seek help from a licensed agent right away.
Are You a Retiree or a Survivor? Your Responsibilities May Be Different
USPS annuitants and survivors need to take initiative. Unlike active employees, retirees are not auto-enrolled in a PSHB plan. If you are an annuitant or a surviving family member of a former USPS employee, you must actively enroll during Open Season or risk losing your coverage.
-
Annuitants should confirm their Medicare status and ensure compliance with Part B enrollment rules
-
Survivors must check if their benefits continue under PSHB and complete enrollment steps during the designated window
How to Confirm Your Eligibility Status
Understanding your classification and eligibility for PSHB and Medicare Part B requires accurate information. You should:
-
Log in to your account on KeepingPosted.org if you’re a retiree
-
Use LiteBlue if you’re an active employee
-
Review all communication from OPM and USPS, including letters about your enrollment classification and required actions
Mistakes That Could Jeopardize Your Coverage
-
Assuming auto-enrollment applies to you — Many retirees believe they’ll be transitioned automatically like active employees. This is false and dangerous.
-
Skipping Medicare Part B enrollment — If you’re required and don’t enroll, you may lose access to drug coverage and other benefits under PSHB.
-
Missing Open Season deadlines — If you don’t act within the enrollment window, you may need to wait an entire year or experience a QLE to make changes.
-
Overlooking exemption status — Just because you’re over 64 doesn’t automatically exempt you from Medicare Part B requirements; you must have retired before the January 1, 2025 cutoff.
-
Failing to update your contact information — If OPM or USPS can’t reach you, you could miss critical notifications about your benefits.
Common Questions About Eligibility
What happens if I delay Medicare Part B enrollment?
If you’re required to enroll and delay signing up, you could face late enrollment penalties and a permanent increase in your monthly premiums.
Can I stay on my spouse’s federal health plan?
If your spouse is a non-USPS federal employee and covered under FEHB, you can continue that plan. But you must confirm this status with your benefits administrator.
What if I’m still working past age 65?
If you’re still an active USPS employee, you aren’t required to enroll in Medicare Part B yet. The requirement kicks in once you retire and become eligible.
Why This Matters for Long-Term Planning
Health coverage is one of the most significant parts of your retirement benefits. If you don’t understand the new PSHB rules, you could:
-
Lose access to affordable drug coverage
-
Face large out-of-pocket healthcare costs
-
Miss enrollment windows and be locked out of changes
-
Incur unnecessary penalties from delayed Medicare enrollment
The PSHB program is built to work in tandem with Medicare. Failing to coordinate these two pieces correctly could lead to financial and health-related hardships.
Don’t Let the 2025 PSHB Changes Catch You Off Guard
The 2025 shift to PSHB plans introduces new eligibility rules and timelines that require your attention. Whether you’re a current USPS employee, a retiree, or a surviving dependent, failing to understand the requirements can put your health coverage at serious risk.
Make sure you confirm your Medicare Part B status, pay attention to enrollment periods, and clarify whether you need to act or you’re automatically covered. If you’re unsure about your classification or what actions to take, speak with a licensed agent listed on this website for professional advice.
