2. What Is Health Insurance?

Health insurance is a contract between you and an insurer where the company agrees to pay for a portion of your healthcare expenses in exchange for a monthly premium. This can include hospital stays, doctor visits, prescriptions, surgeries, and preventive services.

Health insurance can be obtained through:

• Employers (group coverage)

• Government programs (Medicare, Medicaid)

• Private insurers (individual/family plans)

• Marketplaces (ACA exchanges in the U.S.)

3. Why Health Insurance Is Essential

a. Protection from High Medical Costs

Even a single emergency room visit can cost thousands of dollars. Health insurance cushions you from these potential financial disasters.

b. Access to Preventive Care

Routine checkups, vaccinations, and screenings are often free with insurance—helping you catch problems early.

c. Peace of Mind

You don’t need to avoid care due to fear of costs. Insurance gives you confidence to seek timely treatment.

d. Legal Requirements (in some countries)

In places like the U.S., health coverage may be required or highly incentivized under national laws.

4. Types of Health Insurance Plans

a. HMO (Health Maintenance Organization)

• Requires primary care provider (PCP)

• Referrals needed for specialists

• Lower premiums and limited provider network

b. PPO (Preferred Provider Organization)

• More flexible: no referrals required

• Larger provider network

• Higher premiums but greater freedom

c. EPO (Exclusive Provider Organization)

• No referrals, but you must use in-network providers

• Lower cost than PPOs, more flexibility than HMOs

d. POS (Point of Service)

• Combines HMO and PPO features

• Requires PCP and referrals, but allows out-of-network care at a higher cost

e. HDHP (High Deductible Health Plan)

• Lower premiums, higher deductibles

• Often paired with HSA (Health Savings Account)

5. How Health Insurance Works

1. Pay a Premium
   A monthly fee to keep your coverage active.

2. Meet Your Deductible
   You pay out-of-pocket up to a certain limit before coverage kicks in.

3. Coinsurance & Copayments
   After the deductible, you split costs with the insurer (e.g., 20% you, 80% insurer).

4. Out-of-Pocket Maximum
   Once you hit this cap, the insurer pays 100% for covered services.
