Buying health insurance is one of the most important financial decisions you can make — but it’s also one of the most confusing. Between premiums, deductibles, networks, and copays, it’s easy to make mistakes that could cost you a lot in the long run. Whether you’re purchasing insurance for the first time or reviewing your current policy, understanding common pitfalls can save you money, time, and stress.
Here are the top 7 mistakes to avoid when buying health insurance:
1. Choosing the Cheapest Plan Without Looking at Coverage
It’s tempting to go for the plan with the lowest monthly premium. After all, why pay more when you’re healthy, right? But many low-cost plans come with high deductibles, limited coverage, and narrow provider networks. That means if you do need care — even for something minor — you could end up paying significantly out-of-pocket.
Tip: Compare the total cost of each plan, including premiums, deductibles, co-pays, and coverage limits. Make sure it meets both your health and financial needs.
2. Ignoring the Provider Network
Not all health insurance plans allow you to see any doctor you want. Many plans have “networks” — groups of approved healthcare providers and hospitals. If you go to a provider outside the network, you might pay more or your insurance may not cover it at all.
Tip: Before choosing a plan, check whether your preferred doctors, specialists, and local hospitals are included in the provider network.
3. Misunderstanding Key Insurance Terms
Terms like deductibles, co-insurance, out-of-pocket maximums, and premiums can be confusing — and that confusion can cost you. For example, some people think their insurance pays everything once they hit their deductible, but you may still owe a portion of the costs through co-insurance.
Tip: Take time to understand the basic insurance vocabulary. If you’re unsure, ask the insurance provider to explain it clearly — it’s your right as a consumer.
4. Overlooking Prescription Drug Coverage
Not all plans cover the medications you need. Some have a limited drug formulary, and others require prior authorization or charge higher copays for brand-name drugs.
Tip: Make a list of any prescriptions you take and verify whether they’re covered under the plan’s formulary (list of approved medications). Check for any limitations, like step therapy or tiered pricing.
5. Failing to Consider Your Future Health Needs
Your health insurance shouldn’t only be based on your current needs. If you’re planning to have a child, anticipate surgery, or manage a chronic condition, those needs should shape your plan selection.
Tip: Think ahead. If you’re planning major life events or know your health situation could change, choose a plan with more comprehensive coverage and a lower out-of-pocket maximum — even if the monthly premium is slightly higher.
6. Missing the Open Enrollment Period
Health insurance is usually only available during an annual open enrollment period unless you qualify for a special enrollment due to a major life event (like job loss or marriage). Missing that window could leave you uninsured for a year.
Tip: Mark your calendar with enrollment dates and prepare ahead of time. If you experience a qualifying life event, act quickly — you may only have 30–60 days to enroll in a new plan.
7. Not Asking for Help When You Need It
Health insurance is complex, and it’s perfectly okay not to understand every detail. But not asking questions — or trying to figure it out alone — can lead to costly mistakes.
Tip: Use available resources. Reach out to an insurance agent, a health navigator, or the customer service department of the insurer. These professionals are there to help you choose the right plan and understand the fine print.
