PSHB Explained: What USPS Employees and Retirees Need to Know in 2026
Last Updated: May 20, 2026 Reading Time: 9 min
If you work for USPS or retired from it, your health insurance program changed on January 1, 2025. The Postal Service Health Benefits (PSHB) program replaced FEHB for all 1.9 million eligible USPS employees, annuitants, and their family members. The premiums look similar. The carrier names are familiar. But there is one rule that is completely different from FEHB, and if you miss it you lose your health coverage.
This guide covers what PSHB is, how it differs from FEHB, what it costs in 2026, and the Medicare Part B requirement that every postal retiree needs to understand before they hit 65.
Key Takeaways
- PSHB replaced FEHB for USPS on January 1, 2025, under the Postal Service Reform Act of 2022
- 75 plan options across 17 carriers in 2026, compared to FEHB's 132 options
- Average PSHB enrollee premium increase for 2026: 11.3%
- If you retire after January 1, 2025 and become eligible for Medicare, you must enroll in Medicare Part B to keep PSHB coverage
- Retirees who retired on or before January 1, 2025 are grandfathered and exempt from the Part B mandate
- The Part B premium adds $2,434.80 per person annually, but Medicare+PSHB coordination can reduce out-of-pocket medical costs significantly for frequent users
What Is PSHB?
The Postal Service Health Benefits Program is a federal health insurance program created specifically for USPS. It was authorized by the Postal Service Reform Act of 2022 (PSRA, Pub. L. 117-108), signed into law on April 6, 2022.
OPM administers PSHB, the same as FEHB. The plan structures look similar. But PSHB is a separate risk pool with its own carrier contracts, premium rates, and eligibility rules. Postal employees and annuitants are not in the same actuarial pool as other federal workers.
The PSRA required OPM to build PSHB from scratch, which is why Congress appropriated $70.5 million in implementation funds and set a January 2025 effective date. The final rulemaking published in May 2024 gave carriers and enrollees roughly eight months to prepare before coverage switched.
The core financial motivation: move long-term healthcare costs off USPS's balance sheet by integrating retirees into Medicare. That is what drives the Part B mandate covered later in this guide.
How PSHB Differs from FEHB
PSHB and FEHB look similar on the surface: same administrator, same basic benefit structure, many of the same carrier names. The places they differ are what matter.
| Feature | FEHB | PSHB |
|---|---|---|
| Eligible enrollees | All federal civilian employees and retirees | USPS employees, annuitants, and eligible family members only |
| Administered by | OPM | OPM (separate risk pool) |
| Plan options (2026) | 132 options / 47 carriers | 75 options / 17 carriers |
| Avg enrollee premium increase (2026) | 12.3% | 11.3% |
| Medicare Part B required for retirees | No requirement | Mandatory for most retirees after Jan 1, 2025 |
| USPS workers can use | Yes (until Dec 31, 2024) | Yes (only option from Jan 1, 2025) |
| Other federal workers can use | Yes | No |
The shorter plan list in PSHB is not a flaw in the program. It reflects that not every FEHB carrier elected to offer a PSHB-specific contract. Many of the plans with highest postal enrollment, Blue Cross, NALC, APWU, and GEHA, all transitioned. The plans most postal workers were actually using came along. Smaller and regional FEHB-only plans did not.
The Medicare Part B requirement is the sharpest break from FEHB. Under FEHB, taking Part B was your call. Under PSHB, it is no longer optional once you retire after 2025 and turn 65.
2026 PSHB Premiums
PSHB enrollees saw an average 11.3% increase in their enrollee share of premiums for 2026, roughly one percentage point below the FEHB average increase of 12.3%. That gap is partly by design. Greater Medicare integration in PSHB reduces plan claims, which moderates premium growth over time.
Program-Wide Weighted Averages (Biweekly, 2026)
| Enrollment Type | Total Premium | Government Pays (72%) | You Pay |
|---|---|---|---|
| Self Only | $423.11 | $304.64 | $118.47 |
| Self Plus One | $913.19 | $657.50 | $255.69 |
| Self and Family | $989.30 | $712.30 | $277.00 |
Source: OPM 2026 PSHB Premium Tables, weighted average across all 75 plans.
These are averages across all plan options. Individual plan costs vary. Here is a confirmed example using the APWU High Option (plan code 71-019):
APWU High Option Biweekly Premiums (2026, Verified)
| Enrollment Type | Total Premium | Government Pays | You Pay |
|---|---|---|---|
| Self Only | $411.79 | $304.64 | $107.15 |
| Self Plus One | $864.71 | $648.53 | $216.18 |
| Self and Family | $988.24 | $712.30 | $275.94 |
Source: OPM PSHB Plan Brochures, 2026, APWU plan code 71-019.
The government contribution formula follows the same structure as FEHB: the government pays 72% of the program-wide weighted average, up to 75% of any specific plan's total premium. Annuitants and active employees receive the same government contribution.

The Medicare Part B Mandate: The Biggest PSHB Change
Under FEHB, taking Medicare Part B was your call. You could carry FEHB alone in retirement, skip Part B, and stay covered. PSHB removes that option for anyone who retires after January 1, 2025.
Who Must Enroll in Medicare Part B
You must enroll in Medicare Part B, and so must your Medicare-eligible family members, if you:
- Retire on or after January 1, 2025, AND
- Become eligible for Medicare (generally at age 65)
Failing to enroll means losing PSHB coverage. Not a penalty. Not a surcharge. Loss of coverage.
Who Is Exempt from the Part B Requirement
You are not required to enroll in Part B to keep PSHB if:
- You retired on or before January 1, 2025 and are not already enrolled in Part B (grandfathered)
- You were age 64 or older on January 1, 2025 as an active employee (exempt even after you retire)
- You are an active employee (the requirement kicks in when you retire, not while you are working)
The grandfathering rule matters. Roughly 300,000 to 400,000 postal annuitants who retired before 2025 kept their pre-existing PSHB coverage without a Part B requirement attached. They got the new program without the new mandate.
Why Congress Built in the Mandate
The PSRA's Medicare integration provision is the financial mechanism that makes the whole law work. When PSHB-covered retirees have both Medicare Part A and B, Medicare becomes the primary payer for Medicare-covered services. The PSHB plan pays second, covering remaining cost-sharing. That coordination reduces what PSHB plans pay out, which lowers PSHB premiums over time, which reduces what USPS pays in employer contributions.
In short: Congress made postal retirees the secondary payer to Medicare so that USPS's long-term benefit obligation shrinks. The individual retiree bears the Part B premium. The program (and USPS's balance sheet) benefits from lower claims.
The Part B Special Enrollment Period
For postal annuitants who were Medicare-eligible but not yet enrolled in Part B as of early 2024, OPM ran a Special Enrollment Period from April through September 2024. This gave existing retirees a chance to enroll in Part B penalty-free before PSHB launched. Roughly 28,000 postal annuitants enrolled during that window.
If you are a current USPS employee approaching retirement and are close to age 65, you will have a Part B Special Enrollment Period tied to your retirement date. Missing it triggers a 10% late enrollment penalty per 12-month period you were eligible but did not enroll, and that penalty is permanent.
What Medicare + PSHB Actually Costs: FedTools 2026 Analysis
The Part B mandate adds a guaranteed premium on top of your PSHB plan cost. Whether the combination saves or costs you money depends on how much care you use.
FedTools 2026 Analysis: Single USPS Retiree, Age 65+, Retired After January 1, 2025
| Coverage Component | FEHB 2024 (pre-PSHB, voluntary Part B) | PSHB 2026 (Part B mandatory) |
|---|---|---|
| Health plan enrollee premium (monthly est.) | ||
| Medicare Part B premium | Optional ($185/mo in 2025 if enrolled) | Mandatory ($202.90/mo in 2026) |
| Total annual cost if enrolling in Part B | $1,020 + $2,220 = $3,240 | $1,500 + $2,434.80 = $3,934.80 |
| Total annual cost if skipping Part B | $1,020/yr | Not permitted |
Note: Health plan premium figures above are illustrative estimates for comparison framing. For confirmed 2026 per-plan rates, see the APWU High Option table above or check OPM's PSHB premium tables. The APWU High Option self-only enrollee share is $107.15 biweekly ($2,785.90/year).
The key shift: under FEHB, a healthy postal retiree could skip Part B and pay only the health plan premium. Under PSHB, $2,434.80/year per person is a fixed cost once you retire post-2025.
Medicare Part B 2026 Standard Premium and IRMAA
The standard 2026 Part B premium is $202.90/month ($2,434.80/year). If your household income exceeds certain thresholds, Income-Related Monthly Adjustment Amounts (IRMAA) apply:
| Filing Status | 2024 MAGI | Monthly Part B Premium |
|---|---|---|
| Single | Up to $109,000 | $202.90 |
| Single | $109,001–$136,000 | $284.10 |
| Single | $136,001–$163,000 | $365.30 |
| Joint | Up to $218,000 | $202.90 |
| Joint | $218,001–$272,000 | $284.10 |
Source: CMS, 2026 Medicare Parts A and B Premiums and Deductibles fact sheet.
IRMAA is based on your income from two years prior. A high-earning final year before retirement can push you into a higher bracket in year two of retirement, even after income drops.
What You Get for the Part B Premium
Part B pays off fastest for retirees who use healthcare regularly. When Medicare is primary and PSHB is secondary, the combination typically:
- Waives the PSHB plan deductible for Medicare-covered services
- Covers most or all of the 20% Medicare Part B coinsurance
- Picks up Medicare Part A hospital cost-sharing
For a retiree with a chronic condition or regular specialist visits, out-of-pocket costs on Medicare-covered services can drop close to zero. The $283 Part B annual deductible (2026) is often the only cost-sharing before both payers cover the rest.
For a healthy retiree who sees a doctor once a year, the math is less clear. You pay $2,434.80 in Part B premiums and might save a few hundred dollars in avoided cost-sharing. Whether it breaks even depends on your plan's cost-sharing and how much care you use in a given year.
The FEHB + Medicare Part B guide covers the full break-even math in detail. That analysis applies to PSHB retirees too, with one difference: the choice is no longer optional for those who retire after 2025.
Which Carriers Offer PSHB Plans in 2026
PSHB has 75 plan options across 17 carriers for 2026. The major names are:
- Blue Cross Blue Shield (FEP): Basic, Standard, and Plus options. The most widely enrolled plan among both USPS and non-USPS federal workers.
- NALC Health Benefit Plan: High Option. Union-sponsored plan for letter carriers and their families. Has a dedicated Medicare wraparound plan for annuitants with both Part A and B.
- APWU Health Plan: High Option. Union-sponsored plan for postal clerks, maintenance, and motor vehicle service employees.
- GEHA: High Option, Standard Option, and HDHP. A self-insured plan that has been a consistent lower-premium option in the federal benefits space.
- Aetna: Multiple HMO plans in regional service areas.
- Kaiser Permanente: Regional HMO plans where Kaiser operates.
- Humana: Regional plans in select markets.
Not all 47 FEHB carriers elected to offer PSHB plans. Carriers that declined to enter PSHB contracts are still available to non-USPS federal employees through FEHB, but postal workers cannot access them.
Full carrier and plan listings are on the OPM PSHB Carriers page.
PSHB Open Season and Enrollment Rules
PSHB Open Season runs on the same calendar as FEHB: annually in November and December, with changes effective January 1.
- 2025 Open Season: November 10–December 8, 2025 (for 2026 plan year)
- Changes take effect January 1 of the following year
- Outside Open Season, you can change plans only during a Qualifying Life Event (QLE): marriage, divorce, birth of a child, loss of other coverage, and similar events
- USPS employees and annuitants cannot enroll in FEHB plans. That option closed December 31, 2024
- Newly hired USPS employees have 60 days from their hire date to enroll in PSHB
If you miss both Open Season and do not have a QLE, you stay in your current plan for the full plan year. The only exceptions are changes triggered by qualifying events.
Calculate Your Health Plan Costs
Don't auto-renew. Premium differences between PSHB plans can top $100 biweekly for the same enrollment type, and benefit structures vary enough to matter depending on your health situation.
Use the FEHB Calculator to compare annual costs across PSHB-eligible plans side by side. Factor in your expected healthcare use, prescription costs, and whether you have Medicare as a primary payer.
Frequently Asked Questions
What is PSHB and when did it start?
PSHB stands for the Postal Service Health Benefits Program. It replaced FEHB coverage for all USPS employees, annuitants, and eligible family members on January 1, 2025. The program was created by the Postal Service Reform Act of 2022 and is administered by OPM, but operates as a separate risk pool from FEHB with its own plan options, carriers, and rules.
Can USPS employees still use FEHB in 2026?
No. As of January 1, 2025, USPS employees and annuitants are no longer eligible to enroll in FEHB. You must use PSHB. OPM automatically transitioned all USPS FEHB enrollees into their corresponding PSHB plan in January 2025.
Do USPS retirees have to sign up for Medicare Part B under PSHB?
It depends on when you retired. If you retired on or before January 1, 2025, you are grandfathered and not required to enroll in Medicare Part B to keep PSHB coverage. If you retire after January 1, 2025 and become Medicare-eligible (typically at age 65), you and your Medicare-eligible family members must enroll in Part B or you lose PSHB coverage entirely.
How much do PSHB premiums cost in 2026?
The 2026 program-wide weighted average biweekly enrollee share is $118.47 for Self Only, $255.69 for Self Plus One, and $277.00 for Self and Family. The government contributes 72% of the weighted average premium. Individual plan costs vary. The confirmed APWU High Option enrollee share is $107.15 biweekly for Self Only.
What carriers offer PSHB plans in 2026?
PSHB has 75 plan options across 17 carriers in 2026. Major options include Blue Cross Blue Shield (FEP), NALC Health Benefit Plan, APWU Health Plan, GEHA, Aetna, Kaiser Permanente, and Humana. Not all FEHB carriers elected to offer a PSHB variant, which is why PSHB has fewer total options than FEHB's 132 plans.
What happens if a USPS retiree misses Medicare Part B enrollment?
If you retire after January 1, 2025 and fail to enroll in Medicare Part B when you become eligible, you lose PSHB coverage. There is no grace period. You would also face a Medicare Part B late enrollment penalty of 10% for each 12-month period you were eligible but did not enroll, which stays in effect for as long as you have Part B.
