Health Insurance Basics and Policy Provisions
Health policy mechanics
Health insurance transfers morbidity risk and is priced using expected claims, expenses, and reserves. Candidates must distinguish deductibles (amount paid before benefits), coinsurance (percentage sharing after deductible), copayments (fixed charge), and out-of-pocket maximums. Benefit periods, elimination or waiting periods, preexisting-condition rules, and renewability clauses shape coverage. Individual policies may be noncancellable, guaranteed renewable, conditionally renewable, or optionally renewable; group coverage uses a master policy and certificates. Underwriting guards against adverse selection, and claims handling must follow fair-claim-settlement rules. Coordination of benefits prevents duplicate payment when multiple plans cover the same loss; subrogation lets the insurer recover from a responsible third party. HIPAA and ACA rules affect portability, preexisting conditions, and dependent coverage, but details change and should be verified.
Traps: treating coinsurance as a flat fee; confusing an elimination period (time) with a deductible (dollars); assuming all health policies are guaranteed renewable; and forgetting that preexisting-condition rules depend on applicable law. Worked rule: calculate the member's share as deductible plus coinsurance, capped by the out-of-pocket maximum. Example: a $2,000 deductible and 20% coinsurance on a $12,000 claim leaves $2,000 plus 20% of $10,000, or $4,000, before the cap.
