The Postal Service Reform Act of 2022 created the Postal Service Health Benefits (PSHB) program and moved every USPS employee and retiree out of FEHB starting January 1, 2025. It was the biggest change to postal employee benefits in decades — and more than a year later, many postal workers still aren’t clear on what actually changed, what stayed the same, and how to make smart plan choices going forward.
This guide breaks down the real differences between FEHB and PSHB, explains the Medicare cost trap that catches retirees off guard, and walks through how to evaluate your plan options.
The Big Picture: Why PSHB Exists
FEHB covered all federal employees — postal and non-postal — in one giant risk pool. The problem was that USPS carried massive unfunded retiree health liabilities on its books, contributing to billions in paper losses each year. The Postal Service Reform Act fixed this by doing two things: eliminating the pre-funding mandate and creating a separate postal-only health insurance pool that integrates with Medicare.
The logic is straightforward. By requiring Medicare-eligible postal retirees to enroll in Medicare Part B, Medicare becomes the primary payer for their medical claims. That takes the most expensive population (retirees 65+) off the backs of the insurance carriers, which should hold down premium growth for everyone in the postal pool — including active employees.
What Actually Changed
| Feature | FEHB (Before 2025) | PSHB (2025+) |
|---|---|---|
| Who’s in the pool | All federal employees & retirees | Postal employees & retirees only |
| Medicare Part B | Optional for all retirees | Mandatory for most postal retirees (with exceptions) |
| Plan year start | First full pay period in January (employees) | January 1 (all enrollees) |
| Plan carriers | Shared carrier contracts with federal pool | Separate postal-specific contracts |
| Provider networks | FEHB networks | Mostly identical for large carriers; may differ for regional HMOs |
| Prescription drugs (retirees) | Through FEHB plan only | Integrated with Medicare Part D (EGWP) |
| FSAFEDS | Available | Not available under PSHB |
| Benefit levels | Set by carrier | Must be equivalent to FEHB counterpart by law |
What Stayed the Same
More than you might think. PSHB plans are legally required to offer benefits and cost-sharing equivalent to their FEHB counterparts. If your FEHB plan had a $300 deductible and 15% coinsurance for specialist visits, the PSHB version of that plan should have the same structure. The government contribution toward premiums works the same way, FEDVIP (dental and vision) is unaffected, and FEGLI life insurance continues unchanged.
For most active employees, the day-to-day experience of using your health insurance hasn’t changed at all. You still pick a plan during Open Season, you still use the same doctors (especially with large national carriers like BCBS), and your payroll deduction still comes out the same way.
The Medicare Part B Requirement: Who’s Affected
This is the single biggest change and the source of most confusion. Here’s who must enroll in Medicare Part B to keep PSHB coverage:
Required to enroll in Part B: Postal annuitants who become entitled to Medicare Part A after January 1, 2025, plus their Medicare-eligible family members. In practice, this means current employees who retire in the future and turn 65 will need Part B. Anyone hired on or after January 1, 2025 will also fall into this category when they eventually retire.
Not required to enroll in Part B: Postal annuitants who retired on or before January 1, 2025 and were not already enrolled in Part B. Employees who were age 64 or older on January 1, 2025 — even if they keep working past 65 and retire later. Family members of exempt annuitants. Veterans receiving care through the VA. People receiving care through the Indian Health Service. Annuitants living outside the United States.
The Real Cost Math for Retirees
The PSHB plan premium alone doesn’t tell you what your health coverage actually costs. For retirees required to have Medicare Part B, you need to add that premium to get the true monthly number.
Standard income retirees
The standard Medicare Part B premium for 2026 is $202.90 per month, or about $2,435 per year. If you’re married and both of you need Part B, that doubles to roughly $4,870 per year. Some PSHB plans offer partial Part B premium reimbursement, which can offset $800–$1,200 of that annual cost. Check your specific plan brochure for this benefit — it varies by carrier.
Higher-income retirees (the IRMAA trap)
If your modified adjusted gross income exceeds $109,000 (single) or $218,000 (married filing jointly), you’ll pay an Income-Related Monthly Adjustment Amount (IRMAA) surcharge on top of the standard Part B premium. For 2026, total monthly Part B costs range from $284.10 at the first surcharge tier up to $689.90 at the highest.
Under PSHB, there’s an additional hit: Medicare Part D prescription drug coverage is integrated through an Employer Group Waiver Plan (EGWP), and high-income retirees face a separate IRMAA surcharge on Part D as well. This is the “double whammy” that catches postal retirees off guard — Part B IRMAA plus Part D IRMAA on top of your plan premium.
Example: What a retired PS-06 actually pays
Assume a retired clerk at PS-06, single, with a FERS annuity of $28,000 and TSP withdrawals of $15,000/year (total MAGI around $43,000 — well under the IRMAA threshold):
| Cost | Monthly | Annual |
|---|---|---|
| PSHB plan premium (self only, mid-tier plan) | ~$230 | ~$2,760 |
| Medicare Part B (standard) | $202.90 | $2,435 |
| Total health coverage cost | ~$433 | ~$5,195 |
Under FEHB, that same retiree would have paid only the plan premium — roughly $2,760/year. The additional $2,435 for Part B is real money. The upside is that with Medicare as the primary payer, out-of-pocket costs for doctor visits, hospital stays, and procedures typically drop significantly because Medicare covers first and PSHB picks up most of what’s left.
Provider Networks: Are They Really the Same?
For large nationwide fee-for-service plans like BCBS FEP, the answer is effectively yes. BCBS uses the same provider directory for both FEHB and PSHB enrollees, so your doctors, hospitals, and specialists should all still be in-network.
Regional HMOs are where you need to be more careful. Because PSHB and FEHB operate under separate carrier contracts, a regional HMO’s PSHB network may not be identical to its old FEHB network. If you’re in a regional plan, verify your providers before Open Season each year.
One notable change: the NALC Health Benefit Plan exited FEHB for 2026 but remains in PSHB. Non-postal federal employees who were in the NALC plan had to switch to a different carrier. For postal workers, the NALC plan is still available.
For Active Employees: What This Means Now
If you’re currently working and under 64, PSHB is mostly a non-event for you right now. You pick your plan during Open Season, your premiums come out of your paycheck, and you use your insurance the same way you always have. You don’t need to think about Medicare Part B until you’re approaching retirement and age 65.
The two things active employees should do now:
First, review your plan during Open Season every year. In 2026, PSHB enrollee premiums rose by an average of 11.3%. That’s a significant jump, and the increase varies widely by plan. Some plans went up more, some went up less, and a few actually decreased. Don’t just auto-renew — check whether a different PSHB carrier might save you money for equivalent coverage.
Second, start factoring Medicare Part B into your retirement planning now. If you’re 20 years from retirement, the Part B premium will likely be significantly higher than today’s $202.90. Building this into your retirement budget early — and considering Roth TSP contributions to manage your future MAGI — will pay off when the time comes.
How to Evaluate Your PSHB Plan
Whether you’re active or retired, the plan evaluation process is the same as it was under FEHB. Use the PSHB plan comparison tool at health-benefits.opm.gov (not the old FEHB tool at opm.gov — they’re separate). Then pull the actual plan brochure for any plan you’re considering and look at:
Total cost: Premium plus deductible plus expected copays for the services you actually use. If you’re a retiree on Medicare, add the Part B premium to this number. A plan with a lower premium but higher out-of-pocket costs may end up being more expensive overall.
Prescription drug coverage: Compare formularies if you take regular medications. For retirees, PSHB plans integrate with Medicare Part D through an EGWP, which may change your drug costs compared to the old FEHB plan.
Provider network: Confirm your doctors and preferred facilities are in-network, especially if you’re in a regional HMO rather than a nationwide PPO.
Part B reimbursement: Some PSHB plans reimburse a portion of your Medicare Part B premium. If you’re a retiree paying Part B, this benefit can offset $800–$1,200 per year and should factor into your plan comparison.

Calculate Your Retirement Pay →Bottom Line
For active employees, PSHB is essentially the same coverage under a different name. Your focus should be on reviewing plans annually and starting to plan for the Medicare Part B cost in retirement.
For retirees — especially those required to enroll in Part B — the total cost of health coverage has gone up. The trade-off is lower out-of-pocket costs when you actually use medical services, since Medicare pays first. Whether that’s a good deal depends on how much healthcare you use and whether your income pushes you into IRMAA surcharge territory.
The worst thing you can do is ignore it. Review your plan every Open Season. Know your Medicare obligations. And if you’re within five years of retirement, start running the numbers now so there are no surprises.
