Key Takeaways

• Understand how the Medicare Part A hospital deductible works and how it affects federal retirees in 2025.
• Learn to estimate your hospital costs and navigate the PSHB transition with confidence.

If you’re a federal retiree navigating Medicare in 2026, understanding hospital costs is essential—especially with the sweeping changes brought on by the 2025 PSHB transition. This guide answers your questions about the Medicare Part A hospital deductible, how it works in 2025, and what action steps can help you prepare.

What Is the Medicare Part A Deductible?

Definition of the hospital deductible

Medicare Part A helps cover inpatient hospital care, but it’s not free of out-of-pocket costs. The hospital deductible is the amount you must pay for each benefit period before Medicare pays its share for a hospital stay. This deductible is set by the Centers for Medicare & Medicaid Services (CMS) and can change each year.

How it works for hospital stays

The Part A hospital deductible applies for each benefit period—a unique rule that often surprises people. A benefit period begins when you’re admitted to a hospital and ends 60 days after you leave. That means you could pay the deductible more than once in a year if you have multiple, non-consecutive hospital stays. Once you meet the deductible during a benefit period, Medicare helps cover the rest of your inpatient charges for that period.

How Did the 2025 PSHB Transition Affect Retirees?

PSHB basics for federal retirees

The Postal Service Health Benefits (PSHB) Program officially began on January 1, 2025, replacing previous FEHB coverage for many USPS retirees and offering a new integration with Medicare. This was a major shift in how health and prescription benefits coordinate for eligible retirees and their families.

Timeline of the 2025 transition

Planning for the PSHB Program began years earlier, but the true transition took place at the start of 2025. USPS retirees and family members were required to enroll in PSHB plans during a special enrollment window leading up to January. Alongside PSHB, most Medicare-eligible retirees needed to enroll in Medicare Part B to maintain full coverage. As of 2025, these retirees now navigate the new PSHB landscape and its interaction with Medicare Part A.

Why Does the Hospital Deductible Matter?

Costs federal retirees may face

Even with high-quality health insurance, the Part A hospital deductible can be a significant out-of-pocket expense. Federal retirees may face this cost if hospitalized, depending on how their PSHB or former FEHB plan coordinates with Medicare. This is typically a one-time payment for each benefit period, but the potential to pay more than once annually can catch people off guard.

Impact on PSHB and FEHB members

For retirees newly integrated into PSHB, understanding what the hospital deductible covers—and what your plan will help pay—matters more than ever. FEHB and PSHB plans may offer secondary coverage to help pay all or part of the deductible after Medicare pays its share, but this varies by plan. If you’re enrolled only in Medicare Part A (without secondary coverage), you bear the full deductible out-of-pocket. Reviewing your plan’s coordination-of-benefits section is essential.

What Are the 2026 Part A Deductible Amounts?

Latest CMS-updated figures

For 2026, CMS set the Medicare Part A hospital deductible at $1,736 per benefit period. This amount is updated annually, reflecting changes in healthcare costs nationwide. Always check the latest CMS announcements or your plan materials for any mid-year updates or clarifications.

How amounts differ by benefit period

Unlike an annual deductible that resets once each calendar year, the Part A deductible is based on benefit periods. If you’re admitted to a hospital, discharged, and then readmitted after more than 60 days, a new benefit period begins—and you’ll owe a new deductible. This makes estimating yearly costs more complex, especially if you have multiple hospitalizations or chronic conditions. Your plan’s summary of benefits should explain if and how it covers multiple deductibles in the same year.

Do Federal Retirees Pay the Part A Deductible?

FEHB and PSHB coordination with Medicare

For many years, FEHB plans often acted as secondary payers after Medicare. With PSHB launching in 2025, coordination rules can differ. Many PSHB plans will still coordinate with Medicare, helping pay some or all of the remaining hospital costs, including the Part A deductible. However, this is not guaranteed and depends on your specific plan’s guidance.

When you might owe the deductible

You may be responsible for the Part A hospital deductible if your plan does not cover it, or if you’re only enrolled in Medicare without a secondary plan. Even for those with PSHB or FEHB, double-checking your plan’s coordination-of-benefits rules is important. You should always confirm with your benefits administrator or OPM resources to avoid unexpected out-of-pocket costs if you’re hospitalized.

How to Prepare for Hospital Costs in Retirement

Steps to review and estimate expenses

• Read your PSHB or FEHB plan’s summary of benefits annually.
• Check exactly how hospital stays are covered and what costs (if any) you may owe after Medicare pays.
• List possible hospital scenarios (e.g., surgery, complications) and estimate expenses based on your specific plan.
• Compare prior years’ hospital use to anticipate potential future costs.

Resources for benefits counseling

If you need assistance, consider reaching out to the Office of Personnel Management (OPM) benefits counselors, your employing agency’s HR office, or local State Health Insurance Assistance Programs (SHIPs). These resources are designed to help retirees interpret federal and Medicare benefits without offering product recommendations or sales talk.

Which Questions Should Federal Retirees Ask?

Key topics for OPM and plan contacts

• How often might I owe this deductible each year under my current plan?
• What happens if I am hospitalized more than once in a calendar year?

Commonly overlooked premium and coverage details

• Are there any changes to PSHB or FEHB monthly premium costs due to coordination with Medicare?
• Which hospital and specialist networks will be available under my plan after full implementation?
• Are there coverage limitations unique to PSHB that differ from FEHB?
