How to use our Health Insurance reporting to your benefit

The landscape of your health insurance continues to change in a way that adds additional costs directly to you which will impact your savings and your monthly budget. Our information is based on what we see as the most widely used plans. You may find that other plans exists both inside and outside of the federal health platform that you want to explore. Keep in mind what works best for you is not just about budget, but also based on where you life, availability of services in your area and the health/utilization of you/family members. Use this guide to help get your thoughts organized and make sure to confirm your final decisions after reviewing all plan specifications in the plan brochure available provided by each insurer.

Consider re-thinking your approach to health care

As the cost burden shifts toward you as the Federal Employee, you may find that researching and understanding how to use the HDHP plus the HSA/HRA can be a longer term solution to help you lower current costs, accumulate more wealth and tax advantage of a triple tax deduction.

The Short Version

A High Deductible Health Plan with a Health Savings Account is not a cheaper health plan. It is a trade: you accept more financial exposure in a bad-but-not-catastrophic year in exchange for a lower net premium, a plan-funded deposit you keep forever, and the only account in the tax code that is untaxed going in, while growing, and coming out.

Whether that trade is good depends on five questions. The rest of this analysis works through each.

Question	HDHP fits well when…	HDHP is a poor fit when…
Age	Decades of compounding ahead, or peak earning years with catch-up room	Within 6 months of Medicare / Social Security, or already on Medicare
Savings	Liquid savings can cover the out-of-pocket maximum	Savings cannot cover the deductible
Income	Room in the budget to contribute beyond the plan deposit	Every dollar is spoken for; the 10–12% bracket
Health care use	Very low use, or very high use that hits the out-of-pocket max	Moderate, steady spending that lands right around the deductible
Location	Strong in-network access; state conforms to federal HSA tax rules	Thin networks (rural); California or New Jersey residence

The counterintuitive finding: HDHPs are often the right answer at both ends of the health-spending spectrum — the healthy and the very sick — and the wrong answer in the middle. A client with a serious chronic condition who reliably reaches the out-of-pocket maximum frequently pays less in total under the HDHP, because the premium savings outweigh any difference in the catastrophic ceiling. The client most likely to lose money is the one with steady moderate spending who uses up the deductible every year but never gets close to the maximum.

The plan deposit, which FEHB calls the premium pass-through, counts against the IRS limit. It arrives monthly, not as a lump sum in January — a detail that matters for cash flow and is discussed under Savings below.

How HSA money enters and leaves

• Plan pass-through: a portion of your premium deposited monthly. Not taxed, not deductible — it simply never counts as income.
• Payroll allotment: OPM notes many federal employees can make pre-tax HSA allotments through their payroll provider. Pre-tax payroll contributions generally avoid the 7.65% FICA tax as well as income tax — confirm on the Leave and Earnings Statement.
• Direct contribution: deposited to the HSA yourself and deducted on your return. Saves income tax only, not FICA. This is the route for retirees and anyone whose payroll does not offer an allotment.
• One-time IRA transfer: a once-in-a-lifetime qualified HSA funding distribution from a traditional or Roth IRA, up to the annual limit. Useful for someone with an IRA balance but no spare cash flow.
• Withdrawals: tax-free for qualified medical expenses at any age. Before 65, non-medical withdrawals are taxed plus a 20% penalty. After 65, non-medical withdrawals are taxed like a traditional IRA with no penalty.

How the Math Actually Works

An HDHP creates value from three sources and costs you in one place.

• Value 1 — lower net premium. Premium minus pass-through is usually below the traditional plan’s premium. This benefit arrives whether or not you contribute a dollar.
• Value 2 — tax savings on your own contributions. Only realized if you contribute beyond the plan deposit.
• Value 3 — tax-free compounding. Only realized if you leave money in the HSA and invest it rather than spending it each year.
• Cost — deductible exposure. You pay full price for non-preventive care until the deductible is met.

One fairness point that is often missed: for money you spend on care this year, an enrollee in a traditional FEHB plan gets nearly the same tax break by using an FSAFEDS Health Care FSA. The HSA’s real tax edge is on money you do not spend — it rolls over forever, is never use-or-lose, and can be invested. An HDHP enrollee who spends every HSA dollar every year is capturing value 1, but little of values 2 and 3.

By Age

Age drives two things: how long HSA money can compound, and how close the client is to the Medicare wall that ends contributions.

Stage	Fit	Why
Under 35	Strong	Longest compounding runway; typically low health spending; most years land in the HDHP’s winning zone
35–49, young children	Moderate	Pediatric sick visits and urgent care fall under the deductible; strong if savings are solid
35–49, no dependents	Strong	Higher tax bracket raises contribution value; still long runway
50–59	Strong	Peak earnings, $1,000 catch-up at 55, last big accumulation window
60–64	Good	Can build a dedicated fund for retiree premiums and Medicare costs; plan the exit
65+, still working, not on Medicare	Good	May keep contributing while Part A and B are delayed — watch the 6-month rule
65+, enrolled in Medicare	Ineligible	No new contributions; FEHB HDHP converts plan money to an HRA

Under 35 — the compounding case

A young employee who contributes the Self Only maximum and invests it rather than spending it is building what amounts to a second Roth IRA that is also deductible going in. The numbers below assume a 6% annual return, level contributions at 2026 limits, and nothing withdrawn.

Years contributing	Plan deposit only$1,200 / year	Self Only maximum$4,400 / year	Family maximum$8,750 / year
10 years	$15,817	$57,995	$115,332
20 years	$44,143	$161,857	$321,874
30 years	$94,870	$347,856	$691,759
35 years	$133,722	$490,313	$975,054

Even a client who contributes nothing of their own and simply leaves the plan deposit invested accumulates over $94,000 in 30 years. For a FERS employee, this pairs naturally with the TSP: take the full TSP match first, then fund the HSA, then return to additional TSP or IRA savings.

35–49 — the family-formation years

This is the most mixed age band. Children generate frequent, small, unpredictable claims — ear infections, urgent care, stitches — that fall squarely under the family deductible. For a family with strong savings, the HDHP still usually wins on total cost. For a family living close to the edge, a $4,000 family deductible in a year with a broken arm and two rounds of strep is a real hardship. Check whether the specific HDHP covers maternity at no cost before recommending it to someone planning a pregnancy; MHBP’s Consumer Option does.

50–59 — the peak accumulation window

Income, tax bracket, and savings are usually at their highest. The $1,000 catch-up opens at 55, and a married couple can each contribute a catch-up if both are 55 or older — but each catch-up must go into that spouse’s own HSA. Health spending also starts rising in this band, so a client who begins developing a chronic condition should rerun the break-even rather than assume last decade’s answer still holds.

60–64 — plan the exit

HSA eligibility is not tied to employment. A FERS employee who retires at the MRA or at 62, keeps FEHB, and stays in the HDHP can continue contributing until Medicare enrollment — as a direct contribution, since payroll allotments end. The HSA becomes a dedicated fund for three future costs: FEHB premiums after 65, Medicare Part B and D premiums including any income-related surcharge, and out-of-pocket costs Medicare does not cover.

65 and older — the Medicare wall

• Enrolling in Medicare ends new contributions. Enrollment in Part A or Part B makes you ineligible to contribute. The FEHB HDHP then provides a Health Reimbursement Arrangement instead of an HSA deposit.
• The 6-month trap. When you apply for Social Security or Medicare after age 65, Part A is backdated up to six months (though not before the month you turned 65). Contributions made during that retroactive period become excess contributions. Stop HSA contributions six months before applying.
• Claiming Social Security triggers Part A. An employee who wants to keep contributing past 65 must delay both Social Security and Medicare. FEHB coverage through current employment allows Part B to be delayed without penalty.
• The balance keeps working. Existing HSA money remains tax-free for qualified expenses for life, including Medicare Part B and D premiums.
• FEHB premiums in retirement. Premium conversion ends at retirement, so annuitants pay FEHB premiums with after-tax dollars. IRS Publication 969 allows HSA funds to pay premiums for “Medicare and other health care coverage” once you are 65, excluding only Medigap-type supplements. This is widely read to cover an annuitant’s share of FEHB premiums, which would make them effectively tax-free again. Confirm with a tax professional before building it into a retirement income plan.

By Savings

Savings is the single best predictor of whether an HDHP will cause a client real harm. The plan’s worst case is not catastrophic — out-of-pocket maximums are similar to traditional plans — but the timing is front-loaded. The bill arrives before insurance meaningfully engages.

Liquid savings, including HSA balance	Fit	Guidance
Covers the full in-network out-of-pocket max$6,500 Self / $13,000 family, MHBP example	Strong	The HDHP’s risk is fully absorbable. Invest the HSA and pay current bills from cash.
Covers the deductible but not the out-of-pocket max	Good	Keep enough HSA in cash to cover the deductible; invest the rest.
Less than the deductible	Poor	One mid-size claim becomes debt. Choose a traditional plan until savings are built.
Living paycheck to paycheck	Avoid	The HSA can only pay what has been deposited — in January, that is one month of plan deposit.

The January problemAn HSA works like a checking account — you can only withdraw what is in it. The FEHB pass-through arrives monthly, so a Self Only enrollee in MHBP’s Consumer Option has about $100 of plan money in the account at the end of January and about $600 by June. A February surgery that hits the full $2,000 deductible has to be paid from somewhere else.By contrast, the HRA provided to Medicare-enrolled HDHP members, and APWU’s Personal Care Account, are credited up front. That is one of the few ways those structures beat an HSA.Clients should either keep a cash cushion equal to the deductible or start with a year of accumulated HSA balance before relying on it.

The receipts strategy

For clients with solid cash savings, the highest-value approach is to pay current medical bills out of pocket, keep the receipts, and leave the HSA fully invested. There is no deadline for reimbursing yourself, as long as the expense was incurred after the HSA was established. A client can reimburse ten years of saved receipts tax-free in retirement, effectively converting the HSA into tax-free retirement income on demand. This works only for clients whose cash flow can carry medical costs without the HSA.

Where HSA fits in the savings order

1. Build an emergency fund at least equal to the HDHP deductible.
2. Contribute enough to the TSP to capture the full 5% agency match (FERS).
3. Fund the HSA to the IRS limit.
4. Return to additional TSP, Roth TSP, or IRA contributions.

The HSA ranks above additional TSP because it is the only account that is tax-free on both ends for medical use, and medical costs are one of the few near-certain expenses in retirement.

By Discretionary Income

Discretionary income determines whether a client can capture value 2 — the tax savings on their own contributions. The plan deposit and lower premium arrive regardless, so even a client who cannot contribute gets part of the HDHP’s benefit. But the full case depends on contributing.

• Higher income, stronger case. A 24% bracket family contributing through payroll saves about $2,300 in taxes on top of the premium advantage. The HDHP becomes one of the best tax shelters available to them.
• Lower income, weaker case. In the 10–12% brackets the tax savings are modest, and these households are the most likely to be cash-constrained. For them, the HDHP stands or falls on the premium advantage and on having enough savings to survive the deductible — the tax argument alone does not carry it.
• Payroll beats direct. For employees below the Social Security wage base, contributing through payroll rather than directly is worth an extra 7.65% on every dollar.
• High earners phase nothing out. Unlike Roth IRAs, HSAs have no income limits. For clients above the Roth IRA income limits, the HSA is one of the few remaining tax-advantaged accounts.

By Health Care Usage

Usage profile	Fit	Reasoning
Preventive care only, rare sick visits	Strong	Preventive is free in every FEHB HDHP. Nearly all premium savings are kept.
Occasional acute care, under $1,500 / year	Strong	Well inside the winning zone.
Steady moderate use near the deductible	Poor	The losing zone — deductible used up every year without reaching the out-of-pocket max.
Chronic condition, reliably hits OOP max	Good	Compare worst cases; the HDHP’s lower premium often wins despite a similar ceiling.
Brand-name or specialty prescriptions	Weak	Drugs sit under the deductible until it is met; January through March refills are full price.
Weekly therapy or physical therapy	Weak	Visit-based care: copays on a traditional plan often beat full price up to the deductible.
Planned pregnancy	Check plan	Fine if the HDHP covers maternity at no cost, as MHBP’s does; verify for others.
Planned surgery this year	Check math	Compare total cost at that claim level; cash-flow timing matters as much as the total.
Heavy telehealth user	Good	Pre-deductible telehealth is now permanently allowed for HSA eligibility.

The chronic-condition surprise

A client with high, predictable costs often assumes a traditional plan is safer. Run the worst case instead. Using 2026 MHBP Self Only figures, a year that hits the in-network maximum costs $7,796 in the HDHP (net premium $1,296 plus $6,500) versus $8,441 in the Standard Option ($2,441 plus $6,000). The HDHP is $645 cheaper in the worst year — and under the Standard Option, the brochure indicates prescription costs do not count toward that $6,000 ceiling, which can widen the gap further for a heavy medication user.

The prescription caveat

Prescriptions are where HDHPs most often disappoint. Under a traditional plan, a preferred brand drug might be a fixed copay from the first fill. Under an HDHP, the same drug is full negotiated price until the deductible is met. A client on an expensive maintenance medication will meet the deductible early in the year either way — but must be able to fund that front-loaded cost. Some HDHPs cover specific preventive maintenance drugs before the deductible; check the plan’s preventive drug list.

The behavioral risk

Research consistently finds that some people in high-deductible plans skip or delay care they need to avoid paying the deductible. For clients who would realistically do this — especially with a chronic condition that requires monitoring — the HDHP’s savings are an illusion that can turn into larger costs later. A client should choose an HDHP only if they will still see a doctor when they need one.

By Where You Live

Location factor	Effect on HDHP value
California or New Jersey	Neither state recognizes HSAs. Contributions, including the plan deposit, are taxable state income, and interest, dividends, and gains are taxed annually. California has a pending proposal (AB 781) that would change this — watch it. Federal benefits still apply, so an HSA is still worthwhile, but less so.
High-tax conforming statese.g. New York, Oregon, Minnesota, DC	State deduction adds meaningful value on every contribution dollar.
No-income-tax statesAK, FL, NV, NH, SD, TN, TX, WA, WY	No state deduction, but no state tax on HSA earnings either. Value comes from federal income tax and FICA only.
Rural or thin networks	Out-of-network care carries a higher deductible and out-of-pocket maximum — for MHBP’s HDHP, $3,000 and $10,000 Self Only. If the nearest in-network specialist is two hours away, the HDHP becomes much riskier.
High-cost metro areas	Higher negotiated prices burn through the deductible faster, pushing more clients toward the losing zone.
Lower-cost regions	The same deductible buys more care, keeping more clients in the winning zone.
Overseas posting	FEHB plans cover care abroad, but overseas claims are typically paid up front and reimbursed. Cash-flow risk rises; strong savings are essential.
Regional HMO-based HDHPs	Some FEHB HDHPs are local plans. Confirm the plan is offered where the client lives — and where they plan to retire.

For FERS clients planning to relocate at retirement, check both the current location and the retirement destination. An HSA balance is portable anywhere; a local HDHP plan is not.

When HDHPs Are Not Good — Who Should Avoid Them

Not eligible to contribute at all

These clients can enroll in an FEHB HDHP, but the plan will provide an HRA rather than an HSA, which removes the portability, investment, and contribution benefits that make HDHPs attractive.

• Enrolled in Medicare Part A or Part B, including anyone receiving Social Security at age 65 or older, which triggers Part A automatically.
• Within six months of applying for Social Security or Medicare after 65, because of retroactive Part A.
• Covered by TRICARE, which is common among military retirees now in civilian federal service.
• Veterans who received VA medical care in the last three months — unless they have a VA disability rating, in which case VA care does not affect eligibility.
• Anyone whose spouse has a general-purpose health FSA through the spouse’s employer, because it can reimburse the enrollee’s expenses. A limited-purpose (dental and vision) FSA is fine — FSAFEDS offers exactly that as the Limited Expense Health Care FSA.
• Anyone who can be claimed as a dependent on another person’s tax return.

Eligible, but a poor fit

• Savings below the deductible. One mid-year claim becomes credit card debt.
• Steady moderate spenders. People whose annual claims reliably land near the deductible, where the HDHP loses to a traditional plan.
• Heavy brand-name or specialty drug users without the cash to front-load costs.
• Frequent visit-based care — weekly therapy, physical therapy, or regular specialist visits — where fixed copays beat full price.
• Anyone likely to skip needed care because of the deductible.
• Clients who will not contribute or invest. They still get the premium advantage, but give up most of what makes the HSA special.
• Clients in thin-network areas who would routinely go out of network.
• Families where the cheapest traditional plan is nearly as cheap as the HDHP — the head start is too small to survive the deductible gap.

Client Decision Checklist

Count the “yes” answers. Seven or more is a strong HDHP candidate; four to six warrants running the break-even with the client’s own claims history; three or fewer suggests a traditional plan.

#	Question	Yes / No
1	Not on Medicare, TRICARE, recent non-rated VA care, or a spouse’s general FSA?
2	More than six months from applying for Social Security or Medicare?
3	Liquid savings at least equal to the HDHP deductible?
4	Able to contribute at least some money beyond the plan deposit?
5	In the 22% federal bracket or higher?
6	Last two years of claims clearly below the deductible or clearly near the out-of-pocket max?
7	No expensive brand or specialty drugs that would fall under the deductible?
8	Good in-network access where the client lives and plans to retire?
9	Lives outside California and New Jersey?
10	Will still seek care when needed, despite the deductible?

Additional Federal-Specific Points

• HDHP enrollment counts as FEHB coverage for the five-year rule to carry FEHB into retirement.
• The HSA is yours. It stays with you if you change plans, leave federal service, or retire. Balances at the plan’s HSA trustee can be moved to a lower-cost HSA custodian with broader investment options through a trustee-to-trustee transfer.
• A spouse named as beneficiary inherits the HSA as their own. Any other beneficiary receives the full balance as taxable income in the year of death — a planning point for estate-minded clients, who may prefer to spend the HSA down in late retirement.
• Enrollees who join mid-year receive a prorated pass-through.
• FEHB HDHPs cover in-network preventive care in full with no deductible.
• An HDHP enrollee cannot use a regular FSAFEDS Health Care FSA, but can use the Limited Expense Health Care FSA for dental and vision.

What is an HRA in the federal context

When you enroll in an FEHB or PSHB high-deductible plan but aren’t eligible for an HSA, the plan gives you a Health Reimbursement Arrangement instead. Same dollar amount, very different instrument. You become HSA-ineligible by enrolling in Medicare, being on TRICARE, receiving VA care in the last three months without a service-connected disability rating, being claimed as someone’s dependent, or having a spouse with a general-purpose health FSA.

The HRA pays the same qualified medical expenses, but it’s the plan’s money held on your books. You can’t add to it, it earns nothing, and it disappears if you leave the plan — except when you retire and stay in the same plan, where it follows you.

One plan uses an HRA by design rather than as a fallback: APWU’s Consumer Driven Option. Its Personal Care Account ($1,200 Self Only, $2,400 for two or more) is an HRA for every enrollee, HSA-eligible or not. It pays your first claims in full and rolls over up to $5,000 or $10,000 while you stay enrolled.

	HSA	HRA
Who owns it	You	The plan
Who funds it	Plan deposit + you + anyone else	Plan only
Can you contribute?	Yes, up to the IRS limit	No
2027 limit	$4,500 self / $9,000 family, plus $1,000 catch-up at 55	Whatever the plan credits
When the money arrives	Monthly pass-through	Credited in full in January
Earns interest or invests	Yes, tax-free growth	No
Rolls over year to year	Yes, forever	Yes, while you stay in the plan
If you change plans or leave	Keep it	Forfeited
If you retire in the same plan	Keep it	Follows you
Pays Medicare premiums	Yes, after 65	No
Tax treatment	Pre-tax in, tax-free growth, tax-free out	Never taxed; not reportable
At death	Spouse inherits as their own HSA; anyone else owes tax on the full balance	Ends
Requires an HDHP	Yes, plus HSA eligibility	Yes, but no eligibility test

The practical difference: the HRA is a spending account; the HSA is an asset. An HSA-eligible client funding the account fully and leaving it invested is building a retirement asset that can later pay Medicare premiums tax-free. An HRA client gets help with this year’s deductible and nothing more.

Where it shows up in plan selection: a Medicare-enrolled retiree looking at GEHA’s HDHP gets the $1,000 (FEHB) or $1,300 (PSHB) deposit as an HRA, not an HSA. The plan still works — low premium, low out-of-pocket maximum — but the wealth-building argument is gone, and other plans with Part B reimbursement may serve them better.
