Picking a health insurance plan shouldn’t feel like solving a puzzle, but for many families, it does. With so many options, confusing terms, and hidden costs, it’s easy to make a choice that ends up costing you more than it saves.
To save you the headache (and your wallet), here are the top 10 mistakes people make when choosing health insurance — and how you can avoid them.
1. Focusing Only on the Monthly Premium
It’s tempting to pick the cheapest plan just because the monthly premium looks low. But what about the deductible, co-pays, and out-of-pocket maximums? A low premium often means higher costs when you actually use the plan.
👉 Tip: Balance monthly costs with potential yearly expenses. Sometimes paying a little more upfront saves you thousands later.
2. Ignoring the Provider Network
Many people don’t check if their doctor, hospital, or kids’ pediatrician is covered. Out-of-network visits can mean sky-high bills.
👉 Tip: Always confirm your preferred doctors and nearby hospitals are included in the plan’s network.
3. Forgetting About Prescription Coverage
Prescription drugs can make or break your budget. Not all plans cover the same medications, and some require higher co-pays for certain drugs.
👉 Tip: Review the plan’s formulary (list of covered medications) before signing up.
4. Skipping the Fine Print on Out-of-Pocket Maximums
This number is the real safety net. Once you hit it, the insurer pays 100% of covered costs. Many people don’t realize how different these amounts can be between plans.
👉 Tip: For families, make sure the out-of-pocket maximum is manageable in a worst-case scenario.
5. Overlooking Preventive Care Benefits
Annual checkups, screenings, and vaccines are often free under ACA-compliant plans. Families sometimes ignore this, missing out on care that prevents bigger bills later.
👉 Tip: Use preventive care — it’s included and saves money long-term.
6. Not Comparing Plans Every Year
Health insurance changes annually. Networks shift, premiums rise, and new subsidies may apply. Auto-renewing could mean you’re paying more than you need to.
👉 Tip: Shop around every open enrollment period — even if you think you’re happy with your plan.
7. Assuming Employer Coverage Is Always Cheaper
Employer plans are great, but adding dependents can be pricey. In some cases, ACA marketplace plans with subsidies cost less.
👉 Tip: Compare your employer’s family coverage with ACA options side by side.
8. Choosing the Wrong Deductible Level
Some people go too low (and pay high premiums unnecessarily), while others go too high and struggle with big out-of-pocket costs.
👉 Tip: Pick a deductible that matches your family’s typical healthcare usage.
9. Forgetting About Life Changes
Getting married, having a baby, or moving can all affect your insurance options. Families often forget to update their coverage during these “special enrollment” windows.
👉 Tip: Keep track of life events and adjust coverage when they happen — don’t wait until the next open enrollment.
10. Not Asking Questions
Health insurance jargon can be intimidating, but staying silent costs you money. Too many people accept plans without really understanding them.
👉 Tip: Call the insurer, talk to HR, or use a licensed broker. A 10-minute conversation could save you thousands.
