In this post, we’ll walk you through the key health insurance terms and plan types—plain and simple—so you can feel confident about protecting your health and your family’s future.
What Is Health Insurance?
Health insurance is a contract between you and an insurance company. In exchange for a monthly premium, the company agrees to pay part of your medical expenses. But what that "part" includes depends on the specifics of your plan.
Common Plan Types
HMO (Health Maintenance Organization): Requires you to choose a primary care doctor and get referrals to see specialists. Typically lower costs, but less flexibility.
PPO (Preferred Provider Organization): More flexibility in choosing doctors and no referrals needed. Higher premiums.
EPO (Exclusive Provider Organization): Like a PPO, but no out-of-network coverage (except emergencies).
POS (Point of Service): A mix of HMO and PPO. You choose a primary care doctor and can go out-of-network with a referral.
HDHP (High-Deductible Health Plan): Lower monthly premiums, higher deductibles; can be paired with a Health Savings Account (HSA).
1. Premium
Your monthly bill—due whether or not you use your insurance.
2. Deductible
The amount you pay out of pocket before insurance begins to cover services.
3. Copay
A fixed fee for a specific service, such as $30 for a doctor visit.
4. Coinsurance
The percentage of costs you share with your insurer after your deductible. For example, you pay 20%, your insurer pays 80%.
5. Out-of-Pocket Maximum
The most you’ll pay in a year. After you hit this number, your insurance pays 100%.
6. In-Network vs. Out-of-Network
In-network providers have agreed-upon rates with your insurer. Out-of-network costs more.
7. Explanation of Benefits (EOB)
A summary of what your insurer covered, what your provider charged, and what you owe.
8. Prior Authorization
Approval required from your insurer before certain procedures or medications are covered.
9. Preventive Care
Routine services like vaccines and annual checkups—usually covered at no cost in-network.
Meet Eric, a 40-year-old freelance graphic designer. He chose a high-deductible health plan (HDHP) to save on monthly premiums. He rarely got sick—until one day he woke up with severe abdominal pain. It was appendicitis, and he needed emergency surgery.
Total hospital bill: $18,500
Eric’s deductible: $5,000
Coinsurance: 20%
Out-of-pocket max: $7,500
His Final Costs:
$5,000 deductible
20% of the next $12,500 = $2,500
Total: $7,500 (then insurance covered the rest)
Without insurance, Eric would’ve owed $18,500. With it, he paid less than half.
Lesson: Even if you’re healthy, health insurance protects your financial stability from unexpected emergencies.
