Health insurance is a contract between you and an insurer where you pay regular premiums in exchange for coverage of medical costs. Depending on the plan, it may cover hospitalization, outpatient care, prescription medications, dental visits, optical care, and preventive services. Health insurance can be obtained through employers, government programs, or purchased directly from private insurers.
What it covers
- Hospital stays and surgical procedures
- Doctor consultations and specialist visits
- Prescription medications
- Diagnostic tests (blood work, X-rays, MRI)
- Emergency ambulance services
- Mental health services (varies by plan)
- Preventive care and annual check-ups
- Maternity and newborn care (varies by plan)
What it doesn’t cover
- Cosmetic or elective procedures not medically necessary
- Experimental treatments not approved by regulators
- Pre-existing conditions (depending on policy and jurisdiction)
- Certain alternative therapies unless specified
- Injuries from high-risk activities (unless covered by a rider)
How to choose
Consider your health needs, budget, network of providers, deductible amount, co-pay structure, annual out-of-pocket maximum, and whether your current doctors are in-network. Compare waiting periods for pre-existing conditions and check if overseas treatment is covered if you travel frequently.
