HDHP (High-Deductible Health Plan)
A health insurance plan with lower premiums but a higher deductible than traditional plans — and the only plan type that makes you eligible for an HSA.
Definition
A High-Deductible Health Plan (HDHP) is a health insurance plan with higher deductibles and lower premiums than traditional PPO or HMO plans. HDHPs are the only plan type that qualifies you to open and contribute to a Health Savings Account (HSA).
IRS thresholds for 2026:
- Minimum deductible: $1,650 (individual) / $3,300 (family)
- Maximum out-of-pocket: $8,300 (individual) / $16,600 (family)
The HDHP + HSA strategy: The lower premium saves money every month. Those savings, invested in an HSA, grow tax-free. If you're healthy and don't use much healthcare, you can accumulate significant tax-advantaged funds over time. If you need care, the HSA covers the higher deductible tax-free.
Who benefits most from an HDHP:
- Relatively healthy individuals and families who don't expect high medical usage
- People who want to invest through an HSA for future healthcare costs (including retirement)
- Those whose out-of-pocket costs in a year are consistently below the premium savings
Who may be better served by a lower-deductible plan:
- People with chronic conditions requiring frequent care
- Families with young children who have high healthcare utilization
- Anyone who can't absorb the high deductible if a major medical event occurs
Examples
Your HDHP saves you $3,600/year in premiums vs. a PPO. You contribute $3,600 to your HSA. After a year with no major health events, you've kept the $3,600 in your HSA — effectively making healthcare free that year.
Your HDHP has a $2,000 individual deductible. A $4,000 appendectomy means you pay the $2,000 deductible from your HSA (tax-free), then 20% coinsurance on the remaining $2,000 — capped by your out-of-pocket maximum.
A healthy 38-year-old contributes the maximum to an HDHP + HSA for 10 years and invests all HSA funds. At 65, they have a substantial tax-free healthcare reserve for retirement medical expenses.
Frequently asked questions
Is an HDHP always better if I'm healthy?
Not always. You need to be able to cover the deductible if something unexpected happens — the HDHP savings strategy breaks down if you'd have to go into debt to cover the deductible. Have at least 1 year's deductible in savings before relying on an HDHP.
Can I use an HSA to pay my HDHP deductible?
Yes. HSA funds can be used for any qualified medical expense, including payments toward your HDHP deductible. This is the core of the HDHP + HSA strategy.
Do preventive services cost anything on an HDHP?
On ACA-compliant plans, preventive services (annual physical, recommended screenings, immunizations) are covered at no cost even before meeting the deductible — the same as traditional plans.
