One benefits option has a smaller paycheck deduction. Another promises lower bills when you see a doctor. Comparing them means looking at both parts of the price, then checking the providers, prescriptions and account benefits attached to each.
Start with the actual plan documents. The labels on an enrollment screen are useful shorthand, but they cannot tell you what a year of care will cost.
HSA vs PPO: What Are You Actually Comparing?
An HSA is a Health Savings Account: money you hold for medical expenses. A PPO, or Preferred Provider Organization, describes how an insurance plan organizes its provider network. The missing term in many comparisons is HDHP, the coverage that generally makes HSA contributions possible.
IRS Publication 969 defines the HSA as a tax-exempt account and sets the rules for contributing. Our HDHP guide covers the plan definition and annual thresholds. Those are separate questions from whether the insurance uses a PPO network.
One plan can be both. The 2026 G.E.H.A FEHB HDHP brochure states, “We have a Preferred Provider Organization (PPO) Network”, and the plan pays part of the premium into the HSA of each enrollee who qualifies. That is one real plan that is a PPO and HSA-qualified at once.
Is a PPO HSA-Eligible?
Yes, a PPO can be HSA-eligible when the plan is an HSA-qualified HDHP and you personally qualify to contribute. The PPO label alone won't tell you, so check two things: the plan's HSA qualification, then your other coverage.
Under Publication 969, contribution eligibility generally requires qualifying HDHP coverage, no disqualifying additional coverage, no Medicare enrollment and no eligibility to be claimed as someone else's tax dependent. A general-purpose health FSA that covers you can prevent HSA contributions; permitted limited-purpose arrangements work differently.
There is an important current exception to the ordinary HDHP thresholds. Starting in 2026, bronze and catastrophic plans available as individual coverage through an Exchange are treated as HDHPs even if they fail the usual deductible or out-of-pocket requirements. IRS Notice 2026-5, questions 4 and 6, explains that treatment, including purchases of those same plans outside the Exchange. It does not erase the other personal eligibility requirements.
HDHP vs PPO: Costs and Coverage at a Glance
HSA qualification and PPO networks answer different questions, so compare the actual options offered to you. For the table below, the alternatives are an HSA-qualified plan and a PPO that does not qualify for new HSA contributions. Your benefits menu may offer a different pairing.
| Compare | HSA-qualified plan | Non-HSA-qualified PPO |
|---|---|---|
| Premium | HDHP premiums are often lower than traditional coverage | Compare the quoted premium; PPO alone does not set the price |
| Deductible | Generally more spending before the plan shares costs, with exceptions | May offer a lower deductible; read the benefits |
| Visits and prescriptions | Check which services are subject to the deductible | Check copays, coinsurance and any deductible that applies |
| Provider network | Can use a PPO network | PPO network, with additional costs outside it |
| Out-of-pocket exposure | Read the covered, in-network maximum | Read the covered, in-network maximum |
| Employer HSA funding | Count the amount offered and when it arrives | No new HSA contributions based on this coverage |
| Existing HSA balance | Available for qualified medical expenses | Still available for qualified medical expenses |
| Tax savings | Contributions are deductible or pre-tax through payroll, growth is tax free, qualified withdrawals are tax free | No new HSA contributions, so no new HSA tax savings |
Publication 969 lists the HSA's tax benefits: deductible contributions, tax-free earnings and tax-free withdrawals for qualified medical expenses, in an account that stays with you if you change jobs. HealthCare.gov describes the usual HDHP trade-off as a lower monthly premium with more costs paid before insurance shares them. Its PPO definition concerns networks and the additional cost of using providers outside them.
Which Costs Less Over a Year?
The lower-premium option does not necessarily have the lower total cost. Compare premiums plus the medical bills you expect to pay, then examine employer HSA funding and tax benefits separately. Keeping those lines separate shows both the cost of coverage and the resources available to pay for care.
Use this worksheet for each option:
| Worksheet line | What to enter |
|---|---|
| Annual premiums | Your monthly premium multiplied by 12, or your paycheck deduction multiplied by the number of deductions |
| Expected medical spending | Your share of covered visits, prescriptions and procedures under that plan |
| Estimated yearly cost | Annual premiums plus expected medical spending |
| Employer HSA contribution | The promised amount, eligibility requirements and deposit schedule |
| HSA money available now | Your current spendable balance, separate from future deposits |
| Federal tax benefit | A separate estimate based on eligible contributions and your tax situation |
This follows HealthCare.gov's total-cost approach. Your own HSA deposit moves money into an account you own; it is not another insurance charge. Avoid counting both the deposit and the medical bill it later pays as separate costs. An employer deposit adds account funds, but money left unspent is still yours rather than a discount on the insurance premium.
Also compare a high-spending year: annual premiums plus the plan's covered, in-network out-of-pocket maximum. Do not add the deductible again on top of that maximum. This is a covered-care comparison, not a ceiling on every possible bill: premiums, noncovered services and out-of-network spending are among the items excluded from the in-network out-of-pocket limit.
Then check timing. G.E.H.A's example plan passes money into eligible members' HSAs monthly. An employer contribution expected later in the year cannot cover a bill due today. A plan can look less expensive over the full year while requiring more cash early on.
Compare the Care You Actually Use
The useful comparison is what each plan charges for the same care, with the same providers and prescriptions. A deductible alone cannot show that. The Summary of Benefits and Coverage gives you a common format for comparing benefits and includes standardized childbirth and diabetes-care examples.
Use those examples to see how the plans divide costs, rather than assuming that pregnancy or regular appointments automatically make one label better. For care you expect, compare the drug's coverage and cost-sharing, the clinician's network status, and whether a deductible applies before the listed copay. For family coverage, read both the individual and family deductible and out-of-pocket provisions.
Preventive care deserves its own check. Most plans cover specified in-network preventive services without cost-sharing, even before the deductible. That does not make every office visit free. Keep preventive services separate from visits, tests or treatment with different coverage terms.
What Happens to Your HSA if You Switch Plans?
Your existing HSA money stays yours when you change coverage. Spending that balance and making new contributions are separate rights: eligible medical expenses can still be paid from the account, while new contributions depend on your eligibility under the IRS rules.
If you move to a nonqualifying PPO, review your contribution eligibility for the months involved rather than assuming you can keep depositing the same amount all year. For expenses paid from the existing balance, Publication 969 requires that they be incurred after the HSA was established and not already reimbursed elsewhere.
An FSA offered with the new plan has different ownership and spending rules. Our HSA vs FSA comparison covers that account-to-account decision without mixing it up with the insurance network.
Using Your HSA for Purchases That Need an LMN
HSA spending follows the qualified-medical-expense rules, which are separate from what an insurance plan agrees to cover. Publication 969 allows tax-free HSA payments for qualified expenses that insurance has not reimbursed. Choosing coverage is one decision; documenting a qualifying purchase is another.
For a purchase that needs a Letter of Medical Necessity, get the letter before you buy. With Crates, you take a 2 to 3 minute online health assessment, our licensed medical team reviews it, and if you qualify your letter is issued, typically in under 24 hours.
