Compare the whole plan, not one deductible
FEHB HDHPs combine medical coverage with an HSA for eligible enrollees or an HRA for enrollees who are not HSA-eligible. The plan contributes a published premium pass-through to the account. With limited exceptions such as qualifying preventive care, the enrollee generally pays negotiated costs until the deductible is met.
A standard plan may use copays before a deductible, a smaller deductible, or different coinsurance and out-of-pocket rules. That can make routine care more predictable, but it does not guarantee the lowest annual cost. The correct comparison annualizes the premium and models both an ordinary year and a high-cost year.
| Dimension | HDHP/HSA or HRA | Standard plan |
|---|---|---|
| Premium | Often competitive; plan-specific | Plan-specific |
| Before deductible | Most non-preventive care paid by enrollee | May use copays or a lower/no deductible |
| Medical account | HSA if eligible; otherwise HRA | Usually no HSA pass-through |
| Early-year cash need | Can be substantial before account funding accumulates | Often more predictable, but varies |
| Network and drugs | Brochure-specific | Brochure-specific |
Use 2026 HSA rules, not an old threshold
IRS Revenue Procedure 2025-19 sets the 2026 HSA contribution ceiling at $4,400 for self-only coverage and $8,750 for family coverage. It sets the 2026 HSA-qualified HDHP minimum deductible at $1,700 for self-only and $3,400 for family coverage, with maximum out-of-pocket amounts of $8,500 and $17,000 respectively.
The contribution ceiling includes the FEHB plan's premium pass-through, payroll contributions, direct contributions, and contributions from other sources. Subtract the plan's annual pass-through before deciding how much more to contribute. A person age 55 or older may have an additional statutory catch-up amount, but eligibility, partial-year coverage, spouses, and Medicare can change the calculation.
- Confirm that you have no disqualifying non-HDHP coverage or general-purpose health FSA.
- Do not make or receive HSA contributions for months enrolled in Medicare.
- Treat the HRA as different from an HSA: the enrollee cannot contribute and portability rules differ.
- Keep receipts and use current IRS rules before treating a distribution as tax-free.
Run three cost scenarios
Start with a low-use year: annual premium minus the plan's account contribution, plus known preventive or prescription exceptions. Then model an expected year using predictable visits, therapy, prescriptions, labs, and procedures under the brochure. Finally, model a high-cost year using the applicable in-network out-of-pocket maximum and identify services that do not count toward it.
Cash timing matters even when the annual math favors an HDHP. OPM notes that the HSA generally receives the plan pass-through over time, so the full annual amount may not be available for a large January claim. Keep enough liquid cash to meet the net deductible before using tax savings as the deciding factor.
Questions about this FEHB decision
What is the 2026 HSA contribution limit?
The IRS limit is $4,400 for self-only HDHP coverage and $8,750 for family HDHP coverage. Plan pass-through and other contributions count toward that total; eligible people age 55 or older may have a separate catch-up amount.
Does FEHB Self Plus One use the self-only HSA limit?
No. Self Plus One is family HDHP coverage for HSA-limit purposes, so the family ceiling applies when the enrollee is otherwise eligible.
What happens if I am not eligible for an HSA?
OPM says an FEHB HDHP generally establishes an HRA for an enrollee who is ineligible for an HSA. The HRA has different contribution and portability rules; verify the exact brochure.
Is an FEHB HDHP always cheaper than a standard plan?
No. Compare annual premiums, pass-through, deductible, expected care, prescriptions, network, and out-of-pocket exposure. The result is household- and plan-specific.
