10 Common Health Insurance Mistakes and How to Avoid Them

Health insurance plays a critical role in protecting your physical and financial well-being. However, many individuals make costly errors when choosing or using their health plans—mistakes that can lead to unnecessary expenses or lack of essential coverage. Whether you're shopping for a new plan or reviewing your current policy, knowing what pitfalls to avoid is crucial. Here are ten of the most common health insurance mistakes and tips on how to steer clear of them.

1. Not Understanding the Plan Details

Many people sign up for a health insurance plan without thoroughly reviewing what it covers. Skimming through the summary of benefits may leave you unaware of limitations, exclusions, or hidden costs.

How to avoid it: Take time to read the full plan documents. Understand your deductible, copays, coinsurance, network restrictions, and what services require pre-authorization.

2. Ignoring the Provider Network

One of the biggest mistakes is choosing a plan without checking whether your preferred doctors, hospitals, and pharmacies are in-network. Out-of-network care can lead to significantly higher costs—or no coverage at all.

How to avoid it: Use the insurance company’s provider directory or call your doctors directly to confirm they’re in-network for your chosen plan.

3. Focusing Only on the Premium

A lower monthly premium might seem like a great deal, but it can come with high out-of-pocket costs. Many plans with low premiums have higher deductibles and coinsurance rates, which can cost more over the year if you need regular care.

How to avoid it: Compare the total cost of each plan, including premiums, deductibles, copays, and out-of-pocket maximums—not just the upfront price.

4. Missing the Enrollment Deadline

Failing to enroll during the open enrollment period means you may be stuck without coverage for the year or have to rely on limited short-term options.

How to avoid it: Mark your calendar with open enrollment dates. If you experience a qualifying life event—such as marriage, job loss, or having a child—you may be eligible for a special enrollment period.

5. Not Considering Prescription Coverage

Assuming that all medications are covered or not checking the drug formulary can lead to unexpected expenses for your prescriptions.

How to avoid it: Review the plan’s formulary to make sure your medications are covered. Check for generic alternatives, tiered pricing, and any special requirements like prior authorization.

6. Overlooking Mental Health Coverage

Mental health services are essential but are sometimes overlooked when evaluating health insurance plans.

How to avoid it: Ensure the plan covers mental health services such as therapy, counseling, or psychiatric visits. Confirm whether there are limits on the number of visits or if referrals are required.

7. Not Estimating Healthcare Needs

Choosing a plan without assessing your health history or expected usage can lead to under- or over-insuring yourself.

How to avoid it: Consider your past healthcare usage, current medical conditions, and anticipated needs for the upcoming year. This will help you choose a plan that balances cost and coverage effectively.

8. Failing to Use Preventive Services

Many people don’t take advantage of free preventive services like vaccinations, screenings, or annual check-ups included in their plan.

How to avoid it: Review your plan’s list of no-cost preventive services and schedule them regularly to catch potential issues early.

9. Not Asking Questions

Health insurance can be confusing, and failing to ask questions can result in poor plan choices or denied claims.

How to avoid it: Don’t hesitate to reach out to customer service, a licensed insurance agent, or a healthcare navigator to clarify details. Informed decisions start with asking the right questions.

10. Assuming You Don’t Need Insurance

You might feel healthy now, but medical emergencies can happen to anyone. Not having insurance can expose you to enormous out-of-pocket costs.

How to avoid it: Always maintain some level of health coverage—even a high-deductible plan—to protect against major financial losses due to unexpected medical events.
