Key Takeaways

• Understand the eligibility, procedures, and repercussions of declining Medicare Part B with a PSHB plan.
• Staying informed on deadlines and re-enrollment options helps you manage your USPS retiree health benefits wisely.

Navigating the PSHB transition can feel overwhelming, especially when it comes to decisions about Medicare Part B. As a USPS retiree or near-retiree, clear, trustworthy guidance can make all the difference. This article breaks down all you need to know about declining Medicare Part B under the PSHB system—covering who can opt out, deadlines, steps, and the effects on your healthcare coverage for 2026 and beyond.

What Is Medicare Part B in PSHB?

Overview of Medicare Part B

Medicare Part B covers outpatient medical services such as doctor visits, preventive care, and durable medical equipment. It comes with a monthly premium based on your income and is available to most Americans 65 and older, or those with certain disabilities. Enrollment in Part B is voluntary, but many federal retirees consider it to have a significant impact on their overall health care costs and choices.

How PSHB integrates with Medicare

The Postal Service Health Benefits (PSHB) Program began January 1, 2025. For eligible USPS retirees, PSHB plans are designed to work alongside Medicare. If you are eligible for Medicare Part A and Part B, PSHB expects you to enroll as well. Typically, Medicare pays first, and PSHB pays secondary, helping to lower your out-of-pocket costs and broaden your access to providers. However, you do have the right to decline Part B.

Who Can Decline Part B With PSHB?

Eligibility rules for USPS retirees

If you’re a USPS retiree eligible for Medicare, you do have the choice to decline Medicare Part B. This option is available if you’re turning 65, becoming newly eligible, or already covered but considering changes during the PSHB transition. Your eligibility to decline does not remove your eligibility for PSHB—however, it may affect the benefits you receive through your plan.

Exceptions and special cases

Some USPS retirees may have unique circumstances. For example, if you are still actively employed and covered under a group health plan, delaying or declining Part B may not result in a late enrollment penalty. Disabled dependents or survivors may face different rules—explore your specific scenario with a benefits specialist or OPM resource for clarity.

What Are the Deadlines for Declining?

Important PSHB dates to remember

The official start of the PSHB transition was January 1, 2025, with new coverage rules fully in effect for 2026 and beyond. Medicare Initial Enrollment Period (IEP) begins three months before you turn 65 and ends three months after. For most retirees, the PSHB-related deadline to decline Medicare Part B will coincide with these key windows. OPM sends official notices and reminders ahead of decision dates.

Typical enrollment and declination period

You typically must decide whether to enroll in or decline Medicare Part B during your IEP or within Special Enrollment Periods provided for specific life events (such as losing employer coverage). For current USPS retirees, the PSHB open season—usually held in the fall—may offer one more chance to adjust your declaration for the following year. Missing these deadlines can have long-term consequences for premium rates and coverage options.

How Do You Decline Part B in 2026?

Required steps and notifications

If you decide not to enroll in Medicare Part B, you must formally opt out. This process often includes:

• Not responding to (or actively declining) your Medicare Part B enrollment application.
• Notifying the Social Security Administration (SSA) and, if needed, your PSHB plan administrator of your intention to decline.
• Keeping all receipts, letters, and SSA confirmations of your decision for your records.

It’s important to read and follow the instructions in all correspondence from OPM, SSA, and your PSHB provider. Always confirm your status before making healthcare changes.

Key forms and documents

Look out for these documents:

• Social Security’s Medicare Card (if you automatically qualify at 65)
• Medicare Part B Enrollment/Declination Notification Form
• Any PSHB plan-specific waiver or declination statement

File and store these papers safely, as you may need them if you later reconsider or need to show proof of prior coverage.

What Happens After You Decline?

Changes to your PSHB benefits

If you decline Medicare Part B, your PSHB plan remains in place. However, your PSHB coverage may operate on a different payment structure, as it will now become the primary payer rather than secondary. This may mean higher copays or coinsurance, since you are not benefitting from Medicare paying first.

Impacts on healthcare coverage

Declining Part B could affect which providers you can see and what services are covered. Some services may not be covered as fully, and your out-of-pocket costs could be higher depending on the provider. Always review the current PSHB plan brochure to understand how benefits coordinate—or don’t—with Medicare if you have chosen to decline Part B.

Are There Penalties or Consequences?

Medicare late enrollment considerations

If you later decide you want Medicare Part B, you could face a late enrollment penalty. This penalty is typically a permanent increase in your monthly Part B premium, calculated by how many months you delayed enrollment after you were first eligible.

Potential effects on future coverage

Declining Part B now might limit certain options for re-enrollment later. Your choices for changing coverage may be restricted until the next available General Enrollment Period. During this period, coverage delays may apply, and you could have gaps in healthcare access.

Do You Still Need a 1095-B Form?

Purpose of the 1095-B form for USPS retirees

The IRS Form 1095-B verifies that you had minimum essential health coverage for the previous year. It’s useful for proving you met health coverage requirements, even though the penalty for not having insurance has been reduced or eliminated for most Americans.

How 1095-B relates to PSHB transition

You will continue to receive a 1095-B for your PSHB plan as evidence of qualifying health coverage—whether or not you’ve signed up for Medicare Part B. Retain this form for your records and tax preparation in case you need proof of your insurance status.

How Do You Reconsider or Re-Apply?

Returning to Medicare Part B later

Should you change your mind about declining Medicare Part B, you may reapply, but generally only during the Medicare General Enrollment Period (January 1 through March 31). Coverage will not begin until July 1, so consider timing carefully to avoid gaps.

Re-enrollment opportunities and conditions

Special Enrollment Periods may allow you to enroll outside the usual window if you lose coverage under a group health plan or other qualifying life event occurs. If you have doubts about your decision, consult helpful resources (see below) before finalizing your choice.

Who Can Help With PSHB Choices?

Support from OPM and resources

The Office of Personnel Management (OPM) offers support and information to help you understand your PSHB and Medicare options. Visit the OPM website or call their retiree services helpline for official guidance and updates.

Where to find additional guidance

You can also find assistance through trusted retirement counselors, union benefit representatives, and nonprofit organizations focused on supporting federal retirees. Make sure any advice received is up to date and consistent with the rules for 2026 and beyond.
