Critical Illness Rider

A critical illness rider accelerates or adds a lump-sum payment to a life insurance policy upon first diagnosis of a covered critical illness—commonly cancer, heart attack, or stroke—giving the insured cash to use for any purpose including medical bills, lost income, or home modifications.

Definition

A critical illness rider provides the insured with a lump-sum payment—typically equal to a percentage (25–100%) of the life policy's death benefit or a fixed dollar amount—upon first diagnosis of a qualifying critical illness such as invasive cancer, myocardial infarction, stroke, major organ transplant, end-stage renal failure, or coronary artery bypass surgery. The rider benefit reduces the remaining life insurance death benefit dollar-for-dollar; a $500,000 policy with a $100,000 critical illness rider would pay $100,000 at diagnosis and leave $400,000 in remaining death benefit. Unlike the accelerated death benefit rider which requires terminal illness, the critical illness rider pays upon diagnosis even if the insured is expected to survive. The lump sum can be used for any purpose—covering out-of-pocket treatment costs, mortgage payments during recovery, experimental treatments not covered by health insurance, or home modifications. The American Cancer Society estimates the average out-of-pocket cancer expense at $4,000–$20,000 per year depending on treatment type, making a critical illness payment meaningful even when health insurance is in place. Critical illness riders are underwritten and may exclude pre-existing conditions or impose a 30–90 day survival period after diagnosis before payment.
