What Is Health Insurance?
Health insurance is a contract between you and an insurance company where you pay premiums in exchange for coverage of medical costs. The insurance company pays a portion of your healthcare expenses, and you pay the rest through deductibles, copayments, and coinsurance.
Why You Need It:
- Protects against catastrophic medical costs
- Provides access to preventive care and screenings
- Reduces out-of-pocket costs for routine care
- Legally required in some situations (US: Affordable Care Act individual mandate in some states)
- Peace of mind during illness or injury

Most Canadians have private insurance (often through employers) to cover services not included in provincial plans:
- Extended health benefits: Prescription drugs, paramedical services, medical equipment
- Dental insurance: Routine and major dental work
- Vision coverage: Eye exams, glasses, contact lenses
- Travel insurance: Medical coverage outside Canada
Key Health Insurance Terms
Premium
Amount you pay for health insurance every month (or pay period). You pay this whether you use healthcare services or not.
Deductible
Amount you must pay out-of-pocket before insurance starts paying. Example: $2,000 deductible means you pay first $2,000 of covered services, then insurance kicks in.
Copayment (Copay)
Fixed amount you pay for covered service, usually at time of service. Example: $30 copay for doctor visit, $10 for prescription.
Coinsurance
Percentage of costs you pay after meeting deductible. Example: 20% coinsurance means you pay 20% of bill, insurance pays 80%.
Out-of-Pocket Maximum
Most you'll pay in a year for covered services. After reaching this amount, insurance pays 100% for covered services. Example: $8,000 out-of-pocket max.
Network
Group of doctors, hospitals, and other healthcare providers contracted with your insurance. In-network providers cost less than out-of-network.
Prior Authorization
Approval from insurance company required before certain services or medications are covered. Failure to get authorization can result in denied claims.
Explanation of Benefits (EOB)
Statement showing what medical services were provided, what insurance paid, and what you owe. Not a bill, but important to review for accuracy.
Formulary
List of prescription drugs covered by your plan. Drugs are typically tiered (generic, preferred brand, non-preferred) with different copays for each tier.
Understanding Plan Types (US)
HMO (Health Maintenance Organization)
How it works: Choose primary care physician (PCP) who coordinates care. Need referrals for specialists. Must use in-network providers (except emergencies).
Pros: Lower premiums and out-of-pocket costs, predictable copays
Cons: Less flexibility, referrals required, limited to network
PPO (Preferred Provider Organization)
How it works: No PCP required. See any doctor without referrals. Pay less with in-network providers, but can use out-of-network (higher cost).
Pros: Flexibility, no referrals, nationwide coverage
Cons: Higher premiums, deductibles often apply
EPO (Exclusive Provider Organization)
How it works: Must use network providers (except emergencies). No PCP or referrals required. No out-of-network coverage.
Pros: Lower cost than PPO, no referrals needed
Cons: No out-of-network coverage
POS (Point of Service)
How it works: Hybrid of HMO and PPO. Choose PCP, need referrals for specialists. Can use out-of-network at higher cost.
Pros: Some out-of-network coverage, moderate costs
Cons: Requires referrals, more complex rules
HDHP with HSA (High Deductible Health Plan)
How it works: Lower premiums, high deductible. Paired with Health Savings Account (HSA) for tax-advantaged medical savings.
Pros: Lowest premiums, HSA tax benefits, good for healthy people
Cons: High upfront costs before insurance pays, must have savings for deductible
How to Choose the Right Plan
Questions to Ask:
- • What's my total expected healthcare spending? (Consider chronic conditions, medications, planned procedures)
- • Are my current doctors in-network?
- • What prescription drugs do I take? Are they on the formulary?
- • Can I afford the deductible if something major happens?
- • Do I need nationwide coverage or just local?
- • Am I comfortable with referral requirements?
- • What's the total annual cost (premiums + expected out-of-pocket)?
Tool to Compare Plans: Use HealthCare.gov Plan Finder to compare Marketplace plans and estimate total costs based on your expected usage.
