Health insurance is a type of insurance coverage that usually pays for medical, surgical, prescription drugs, and sometimes dental expenses incurred by the insured.

Health insurance can reimburse the insured for expenses incurred from illness or injury, or pay the care provider directly.

This is often included in the employer benefit package as a way to persuade standard employees, premiums are partially covered by the employer but are often also deducted from employee salaries.

The price of health insurance premium is deductible for the payer, and the benefits received are tax-free, with few exceptions for corporation employees.
