What Is Health Insurance

Health insurance is an agreement between an individual and an insurance provider.

In exchange for regular payments, known as premiums, the insurance company agrees to help cover certain healthcare expenses according to the terms of the policy.

Depending on the plan, health insurance may help cover:

• Doctor visits
• Hospital stays
• Emergency treatment
• Prescription medications
• Laboratory tests
• Preventive care
• Surgical procedures
• Specialist consultations

Coverage varies depending on the insurance provider and policy.

Why Health Insurance Is Important

Health insurance offers several benefits.

Financial Protection

Medical expenses can be costly. Insurance helps reduce out-of-pocket costs for covered services.

Access to Healthcare

Insurance may make it easier to access doctors, hospitals, specialists, and preventive care services.

Peace of Mind

Knowing you have financial support for covered healthcare needs can reduce stress during medical emergencies.

Preventive Care

Many health plans encourage preventive healthcare through routine checkups, screenings, and wellness programs.

Common Health Insurance Terms Explained

Premium

A premium is the amount you pay for your health insurance policy.

Premiums may be paid:

• Monthly

• Annually

You generally pay the premium regardless of whether you use healthcare services.

Deductible

A deductible is the amount you must pay toward covered healthcare costs before your insurance begins sharing certain costs.

Deductible rules vary depending on the policy.

Copayment (Copay)

A copayment is a fixed amount you pay for a healthcare service, such as a doctor’s visit or prescription medication.

Coinsurance

Coinsurance refers to the percentage of healthcare costs shared between you and the insurance provider after applicable deductible requirements have been met.

Out-of-Pocket Maximum

This is generally the maximum amount you are required to pay for covered services during a policy period before the insurer covers eligible additional costs according to the plan.
