5 Common Health Insurance Mistakes (And How to Avoid Them)

Health insurance can be confusing—and one wrong move could cost you hundreds (or even thousands) of dollars. Whether you’re picking a new plan or using your current coverage, many people make the same avoidable mistakes.

Here are five common health insurance slip-ups and how to dodge them:


1. Picking the Cheapest Plan Without Checking Coverage

The Mistake: Going for the lowest premium without considering deductibles, copays, or what’s actually covered.
Why It’s Bad: That “$99/month” plan might leave you paying way more out-of-pocket when you actually need care.
✅ How to Avoid It:

  • Compare total costs (premium + deductible + copays).
  • Check if your regular doctors and meds are covered.
  • Ask: “What’s the worst-case yearly cost if I get sick?”

2. Ignoring the Provider Network

The Mistake: Assuming all doctors/hospitals accept your insurance.
Why It’s Bad: Going “out-of-network” can lead to huge bills—some plans won’t cover a penny.
✅ How to Avoid It:

  • Search your insurer’s online directory before booking appointments.
  • Always confirm with the doctor’s office (“Do you take [Your Insurance]?”).
  • In emergencies, go to the nearest hospital—but follow up in-network afterward.

3. Not Checking Prescription Coverage

The Mistake: Thinking all medications are covered equally.
Why It’s Bad: Your plan might only pay for generic versions—or exclude certain drugs entirely.
✅ How to Avoid It:

  • Look up your insurer’s formulary (list of covered drugs).
  • Ask your doctor for generic or lower-cost alternatives.
  • If your med isn’t covered, appeal or apply for an exception.

4. Skipping Preventive Care

The Mistake: Avoiding check-ups to “save money.”
Why It’s Bad: Many plans cover free annual physicals, vaccines, and screenings—catching problems early saves $$$ later.
✅ How to Avoid It:

  • Use your free preventive benefits (ACA-compliant plans include them).
  • Schedule yearly check-ups even if you feel fine.
  • Know your plan’s wellness perks (like discounts on gym memberships).

5. Not Reviewing Your Plan Yearly

The Mistake: Auto-renewing without checking changes.
Why It’s Bad: Networks, drug coverage, and costs change every year—your perfect plan might not stay perfect.
✅ How to Avoid It:

  • During Open Enrollment, compare plans (even if you like yours).
  • Look for new benefits (telehealth, mental health, etc.).
  • Update your info if your health needs changed (new meds, chronic conditions, etc.).

Final Tip: Don’t Be Afraid to Ask for Help!

If insurance jargon makes your head spin:

  • Call your insurer’s customer service (yes, they can explain things!).
  • Use a licensed broker (they’re free—they get paid by insurers).
  • Check HealthCare.gov or your state’s marketplace for guidance.

Better to double-check now than get a surprise bill later!
