1. What is Health Insurance?

Health insurance is a contract between you and an insurance provider that helps cover medical expenses. In exchange for a monthly premium, the insurer agrees to pay part or all of your medical costs, depending on the policy you select.

Covered services may include:

• Doctor visits

• Hospital stays

• Emergency care

• Prescription drugs

• Mental health services

• Preventive care

2. Why Health Insurance is Important

Without insurance, even a minor medical issue can cost hundreds or thousands of dollars. Major illnesses, surgeries, or emergencies can lead to devastating debt. Health insurance provides:

• Financial protection

• Access to regular and preventive care

• Discounted rates with in-network providers

• Peace of mind for unexpected health events

3. Types of Health Insurance Plans in 2025

Understanding plan types can help you choose the right one for your needs:

b. PPO (Preferred Provider Organization)

• More flexibility in choosing doctors

• No referrals needed

• Higher premiums and deductibles

c. EPO (Exclusive Provider Organization)

• No coverage for out-of-network care (except emergencies)

• No PCP requirement

• Lower premiums than PPOs

d. POS (Point of Service)

• Hybrid of HMO and PPO

• 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 Health Savings Accounts (HSA)

5. What Does Health Insurance Cost in 2025?

Costs vary depending on your plan, location, income, and age.

Main costs include:

• Premium: Monthly payment to keep your policy active

6. How to Buy Health Insurance

Purchased directly from insurance companies—often more expensive, but with more plan options.

8. Understanding Your Policy

Every health insurance plan comes with a Summary of Benefits and Coverage (SBC) document. It includes:

• What’s covered and not covered

• Your copay, deductible, and coinsurance

• List of in-network providers

• Instructions for filing claims and appeals

9. Using Your Insurance Wisely

• Stay in-network: Going to out-of-network providers may cost more or not be covered.

• Use preventive care: Most plans cover annual check-ups, vaccines, and screenings for free.

• Track your spending: Use your insurer’s website or app to monitor your deductible and out-of-pocket total.

• Use urgent care for minor issues: It’s cheaper than the emergency room.

• Assuming all providers are in-network
