Health Insurance Basics and Policy Provisions
Cost sharing
The deductible is what the insured pays before benefits begin. Coinsurance is a percentage split after the deductible; a copayment is a flat dollar amount, often for a visit or prescription. The out-of-pocket maximum caps the insured's exposure for covered in-network services. Keep the distinction sharp: coinsurance is a percentage, copay is a flat fee.
Renewability clauses
Cancelable: the insurer may cancel and raise rates at any time. Optionally renewable: the insurer may decline renewal at a premium date. Conditionally renewable: renewal is guaranteed unless the insured fails to meet stated conditions. Guaranteed renewable: the insurer must renew but may raise the premium by class. Noncancellable: the insurer can neither cancel nor raise the premium, and may only reduce benefits by class. Noncancellable is the strongest protection for the insured and the most expensive.
Other core provisions
The grace period (commonly 30 or 31 days) preserves coverage for a late payment. Reinstatement restores a lapsed policy on proof of insurability and payment of overdue premium. The time limit on certain defenses (incontestability) bars the insurer from contesting the application after about two years for fraud. A preexisting-condition provision limits coverage for a stated period. Coordination of benefits prevents double payment when two plans cover the same loss, using the primary/secondary rules. Probationary and elimination periods delay when benefits begin; an elimination period is the disability waiting period.
Worked example
A plan has a $1,000 deductible, 20% coinsurance, and a $5,000 out-of-pocket maximum. A $6,000 covered claim leaves the insured paying $1,000 plus 20% of $5,000 = $2,000 total. Once cumulative out-of-pocket hits $5,000, the plan pays 100%.
