How High-Deductible Health Plans Work

The options above show a situation where it clearly makes sense to choose the HDHP. With either plan, you’ll end up spending $4,500 of your own money in premiums and deductibles if your medical expenses for the year are at least as much as your deductible. But with the HDHP, you’re only guaranteed to spend $1,500 in premiums, unless you know for a fact what your upcoming medical expenses will be.

Also, having the HDHP lets you contribute to a health savings account. If you’re in the 24% federal tax bracket and you do incur $3,000 in medical expenses, you could use your HSA to pay for them with pre-tax dollars. If you used post-tax dollars, that same $3,000 in medical expenses could cost you nearly $4,000. If you chose the lower deductible plan (the non-HDHP), you could pay $2,550 of your $3,000 in medical expenses from a flexible spending account (FSA) if your employer offers one. Then, you’d have similar tax savings with the non-HDHP.

Even this simplified example isn’t really that simple. Similarly, most real-life situations aren’t clear-cut as to whether you should select a high-deductible or low-deductible plan. You’ll need to do the math for your own circumstances, taking into account your likely medical expenses for the year and the premiums, deductibles, and out-of-pocket maximums for the available plans.

High-Deductible Health Plans and Preventive Care

If you do choose the high-deductible plan, you’ll still have 100% coverage for preventive services from in-network providers before you meet your deductible because of the Affordable Care Act requirements. Quite a few services fall into this category, and you aren’t responsible for any copayment or coinsurance for any of them. Here are a few examples taken from Healthcare.gov:

Adults

• Abdominal aortic aneurysm: one-time screening for men of specified ages who have ever smoked
• Aspirin use to prevent cardiovascular disease for adults of certain ages
• Blood pressure screening
• Cholesterol screening for adults of certain ages or at higher risk
• Colorectal cancer screening for adults 45 to 75
• Depression screening
• Diabetes (Type 2) screening for adults 40 to 70 who are overweight or obese
• Certain immunizations for adults, such as the flu shot

Women

• Breastfeeding comprehensive support and counseling from trained providers, and access to breastfeeding supplies for pregnant and nursing women
• Contraception: Food and Drug Administration-approved contraceptive methods, sterilization procedures, and patient education and counseling, as prescribed by a healthcare provider for women with reproductive capacity (not including abortifacient drugs). This does not apply to health plans sponsored by certain exempt “religious employers.”
• Breast cancer mammography screenings every one to two years for women over 40
• Cervical cancer screening every three years for women 21 to 65
• Osteoporosis screening for women over age 65 or women age 64 and younger who have gone through menopause
• Well-woman visits to get recommended services

Children

• Autism screening for children at 18 and 24 months
• Behavioral assessments
• Blood pressure screening
• Depression screening for adolescents
• Developmental screening for children under age 3
• Hearing screening for all newborns
• Vaccines for illnesses such as whooping cough, influenza and chickenpox

HSA Eligibility

As noted already, the other major advantage of having an HDHP, besides typically lower premiums, is that it allows you to contribute to a health savings account. Because HSA contributions come from pre-tax dollars, you can save a considerable amount on your medical expenses when you pay for them with your HSA. For example, if you’re in the 24% federal tax bracket, a $100 medical bill will effectively cost you only $76. You must have an HDHP to be eligible to contribute to an HSA and to receive any employer contributions to your HSA.

In fact, “free” money in the form of optional employer contributions to your HSA is another potential benefit of having an HDHP and an HSA. In addition, you don’t have to keep your HDHP forever to take advantage of an HSA in future years. Contributions carry over from one year to the next, and you can invest your contributions to help them grow, too. In the future, even if you no longer have an HDHP, you can use money previously deposited to your HSA to pay for health expenses.

Disadvantages of High-Deductible Health Plans

The big drawback to choosing an HDHP is having potentially high out-of-pocket expenses for the year. As noted above, that means HDHP plan participants could face out-of-pocket costs of up to $5,700 for individual coverage or $10,500 for a family plan in 2025.

Another potential problem with enrolling in an HDHP is that you may find yourself wanting to skip doctor visits because you’re not used to having such high out-of-pocket costs. Don’t choose an HDHP if it will cause you to avoid doctors, procedures or prescriptions because you want to save money in the short term. Neglecting medical issues could end up costing you more in the long term, plus you’ll be jeopardizing your health.

High-Deductible Health Plans and You

Whether or not it makes sense to have an HDHP depends on your life stage and the associated medical expenses you’re likely to incur. In particular, you should weigh the benefits of lower monthly premiums against the risk of accumulating higher deductibles and out-of-pocket expenses that can add up and overwhelm some consumers.

If you’re young and healthy and rarely go to the doctor or take prescription medication, you’ll probably save a lot of money by choosing an HDHP since the premiums are lower. If you’re planning to have a baby in the near future, an HDHP might not be a good choice since the costs of hospital childbirth are high and your out-of-pocket expenses could easily reach your high out-of-pocket maximum. In that case, it may actually be more cost-effective to opt for a plan with lower deductibles and lower out-of-pocket costs instead, even if the premiums are initially higher.

Similarly, an HDHP also might not make sense if you have young children since they tend to visit the doctor frequently, which can quickly accumulate deductibles. When your children are older and if they and you are healthy, an HDHP might make more sense. On the other hand, if anyone covered by your plan has a chronic condition that needs ongoing treatment, you might benefit from a plan with a lower deductible.

Finally, you’re statistically more likely to have higher medical expenses if you’re older, so you may not want to take a chance on an HDHP. But if you’re still in good health and have no reason to anticipate expensive healthcare costs, an HDHP might work for your circumstances despite your age.

Whether an HDHP will save you money always depends on the details of the specific plans available to you and your expected medical expenses for the year. An HDHP is not automatically a better or worse deal than an insurance policy with a lower deductible just because your circumstances fall into a specific category. You always have to do the math for your own situation. 

The Bottom Line

An HDHP can save you money through lower premiums and the tax break you can get on your medical expenses through an HSA. It’s important to estimate your health costs for the coming year to see how much you might pay out of pocket with an HDHP before you sign up. In some cases, a plan with a lower deductible will save you money, even though it will usually have higher premiums and won’t let you have an HSA. In addition, if your employer offers it, you can use an FSA to get tax savings on your medical expenses with a lower-deductible plan.
