In exchange for monthly premiums, the insurer helps pay covered healthcare expenses.
Health insurance may help cover:
- Doctor visits
- Hospital stays
- Emergency care
- Prescription medications
- Preventive care
- Surgical procedures
Coverage varies depending on the policy.
Why Is Health Insurance Important?
Healthcare costs continue to rise.
Without insurance, even routine medical treatment can become expensive.
Health insurance helps:
- Reduce medical expenses
- Protect savings
- Improve access to healthcare
- Provide financial security
- Support preventive care
It serves as both a health and financial protection tool.
How Health Insurance Works
The basic process is simple.
Step 1: Pay Premiums
You pay regular monthly premiums.
Step 2: Receive Medical Care
Visit healthcare providers when needed.
Step 3: Insurance Shares Costs
The insurer helps pay covered expenses according to your policy.
Step 4: Pay Your Share
Depending on the plan, you may be responsible for:
- Deductibles
- Copayments
- Coinsurance
Important Health Insurance Terms
Understanding these terms is essential.
Premium
A premium is the amount you pay each month to maintain health insurance coverage.
Example
Monthly Premium:
$300
You pay this amount regardless of whether you use healthcare services.
Deductible
A deductible is the amount you pay before insurance begins sharing costs.
Example
Deductible:
$1,500
You may need to pay the first $1,500 of covered medical expenses before insurance contributes.
Copayment (Copay)
A copay is a fixed fee for specific healthcare services.
Example
Doctor Visit Copay:
$30
You pay $30 while the insurer covers the remaining eligible costs.
Coinsurance
Coinsurance is the percentage of medical expenses you pay after meeting your deductible.
Example
80/20 Coinsurance
- Insurance pays 80%
- You pay 20%
Out-of-Pocket Maximum
This is the most you'll pay for covered services during a policy year.
After reaching the limit, insurance generally covers eligible expenses at a higher level.
