Why is an HDHP with an HSA often cheaper than a low-deductible PPO?

An HDHP saves $1,800 to $4,500 per year in lower payroll premiums, often includes an employer HSA contribution ($500 to $1,000 free cash), and provides a triple-tax shield on HSA deposits. These guaranteed savings usually exceed the higher deductible even in years with high medical expenses.

When should someone choose a Traditional PPO instead of an HDHP?

A Traditional PPO may be preferable if you do not have sufficient liquid emergency savings to pay the upfront deductible, take expensive non-generic specialty medications requiring immediate flat copays, or anticipate high frequent ongoing doctor visits without having cash to seed an HSA.

What happens to unspent HSA money at the end of the year?

Unlike a Flexible Spending Account (FSA) which has a 'use-it-or-lose-it' rule, HSA funds never expire. All unused contributions and investment earnings roll over year after year indefinitely and belong to you even if you change employers.

The Open Enrollment Deductible Illusion: Why Fear of High Deductibles Costs Families $3,000+ Every Year

An actuarial breakdown of payroll deductions, employer HSA seeds, FICA tax avoidance, and why HDHPs mathematically dominate PPOs.

The Net Cost Formula

To compare health plans objectively, always calculate Total True Out-of-Pocket Cost: Total Premiums + Medical Out-of-Pocket - Employer HSA Contribution - Tax Savings. Because an HDHP saves $2,000+ in premiums and provides tax deductions on HSA savings, it often provides a superior safety net even during hospitalizations.

Frequently Asked Questions (HDHP vs. PPO Open Enrollment)

How do preventive care checkups work under an HDHP?

Under the Affordable Care Act (ACA), all qualified HDHPs must cover standard preventive care (annual physicals, routine pediatric checkups, vaccines, mammograms, and cholesterol screenings) at 100% with $0 copay and $0 deductible. You do not pay anything toward your deductible for preventive health.

Can I use my HSA to pay for dental, vision, and chiropractic care?

Yes! IRS Publication 502 allows HSA funds to be spent 100% tax-free on qualified dental cleanings, fillings, braces/Invisalign, eyeglasses, contact lenses, LASIK surgery, and chiropractic care, even if your health insurance does not cover them.
