Postal Workers in 2025 Face a Medicare Rule That’s Not Well Advertised

Key Takeaways

• In 2025, many Medicare-eligible Postal retirees and family members must enroll in Medicare Part B to keep their Postal Service Health Benefits (PSHB) coverage active.

• There are exemptions, but they apply narrowly and require a clear understanding of eligibility, timelines, and consequences for opting out.

As of January 1, 2025, Postal Service employees and retirees are no longer covered by the traditional Federal Employees Health Benefits (FEHB) Program. Instead, you are now part of the Postal Service Health Benefits (PSHB) Program. While the coverage structure appears similar, the rules have changed—especially when it comes to Medicare.

One key difference? Your eligibility for continued PSHB coverage often hinges on Medicare Part B enrollment once you become Medicare-eligible.

What the 2025 Medicare Rule Means for You

If you’re a Postal retiree—or a family member—who is eligible for Medicare as of 2025 or beyond, a new requirement applies: you must be enrolled in Medicare Part B to maintain full PSHB medical and drug coverage. This rule is mandated by the Postal Service Reform Act of 2022 but takes effect now in 2025.

You Must Enroll in Part B When First Eligible

Unless you qualify for a narrow exemption, failing to enroll in Medicare Part B when first eligible could mean:

• Losing access to comprehensive PSHB coverage

• Being left with limited or no drug coverage

• Facing late enrollment penalties if you decide to join Part B later

This rule catches many retirees off guard, especially those accustomed to the more flexible rules under FEHB.

Who Must Enroll and Who’s Exempt

The Medicare Part B requirement doesn’t apply to everyone. Here’s how to know where you stand.

Required to Enroll:

You must enroll in Medicare Part B in 2025 if:

• You are a Postal Service annuitant or family member who is already enrolled in Medicare Part A or becomes eligible for Medicare in 2025 or later.

• You want to keep your PSHB coverage active for both medical and prescription drugs.

Exemptions May Apply If:

• You retired on or before January 1, 2025

• You are age 64 or older as of January 1, 2025

• You reside outside the U.S. and its territories

• You qualify for health services through the VA or Indian Health Services

Even if you meet one of these criteria, you are not automatically exempt. Documentation or proof may be required, and each exemption is subject to review.

Part B Enrollment Timelines That Matter

Timing is critical when it comes to enrolling in Medicare Part B. If you miss your window, you may have to wait months before coverage kicks in—and you’ll likely pay more.

Initial Enrollment Period (IEP):

This is a 7-month window:

• Begins 3 months before you turn 65

• Includes your birth month

• Ends 3 months after the month you turn 65

Enroll during the first three months to avoid delays in coverage.

General Enrollment Period (GEP):

If you miss your IEP, you can enroll between January 1 and March 31 each year. However, coverage won’t begin until July 1—and you’ll likely face a late enrollment penalty.

Special Enrollment Period (SEP) for PSHB:

In 2024, a one-time Special Enrollment Period was offered from April 1 to September 30 for Medicare-eligible Postal annuitants not enrolled in Part B. That window has now closed. Moving forward, no such SEP is expected unless you experience a qualifying life event.

Why Medicare Part B Matters for PSHB Plans

PSHB plans are now designed with Medicare integration in mind. If you’re not enrolled in Part B, you’re likely to face higher out-of-pocket costs, limited provider access, or denial of claims. Here’s why:

• PSHB assumes Medicare Part B is your primary insurance

• Plans coordinate benefits with Medicare to reduce your share of expenses

• Prescription drug coverage is linked to Medicare enrollment under the EGWP model (Employer Group Waiver Plan)

If you decline Part B, you may lose drug coverage entirely under PSHB.

How the Prescription Drug Rule Adds to the Confusion

Another lesser-known rule affects your drug coverage under PSHB. If you are eligible for Medicare but opt out of Part B, your PSHB drug coverage is automatically dropped. This is because the prescription benefits are delivered through a Medicare Part D EGWP plan.

Without Part B, you are not eligible for the EGWP, which means:

• You lose access to affordable prescription drugs

• You may need to purchase separate coverage on your own

• Your ability to rejoin the plan later may be restricted

Don’t Rely on Automatic Enrollment Notices Alone

Many retirees assume they’ll be automatically protected or that someone will notify them when action is required. That’s a dangerous assumption.

In 2025, you may receive an enrollment notice, but it is your responsibility to:

• Read the Annual Notice of Change (ANOC)

• Confirm your Medicare Part B status

• Contact the PSHB Navigator Help Line if you’re unsure

Financial Implications of Skipping Part B

Declining Medicare Part B doesn’t just limit your PSHB benefits—it can lead to long-term financial consequences:

• Late Enrollment Penalties: For each 12-month period you delay, your Part B premium increases by 10%—permanently.

• Uncovered Services: Without Part B, your PSHB plan may not pay for major outpatient services like diagnostic testing, durable medical equipment, and physical therapy.

• Prescription Drug Gaps: Without access to the EGWP, medication costs can spiral without subsidy protections.

Coordination of Benefits Now Hinges on Part B

Before 2025, many FEHB enrollees delayed Medicare Part B enrollment without immediate consequences. That is no longer the case under PSHB.

In 2025:

• PSHB plans are structured assuming Medicare will pay first

• If you don’t have Part B, your plan becomes secondary payer to…nothing

• This shifts full financial responsibility to you for covered services

This change impacts not just retirees, but also Medicare-eligible spouses or survivors relying on your PSHB coverage.

What You Can Do Right Now

If you haven’t taken action yet, it’s not too late. Here’s what to do:

• Check Your Medicare Status: Are you eligible? Are you enrolled in both Parts A and B?

• Review Your PSHB Plan: See how it handles Part B non-enrollment

• Call for Guidance: Contact a licensed professional listed on this website for a plan review

Why Early Planning Makes a Big Difference

The key to protecting your PSHB benefits in 2025 is awareness and action. Late decisions can be costly—and irreversible.

• Know your enrollment window

• Understand your exemption status

• Secure both medical and drug coverage by enrolling in Part B

Staying Covered and Informed in 2025

Medicare coordination is now at the core of your Postal health benefits. Whether you’re already retired or planning to retire this year, don’t underestimate how much hinges on a single enrollment decision.

Missing the Medicare Part B requirement could strip you of drug coverage, increase your costs, and reduce your access to care.
