Critical illness insurance pays one cash lump sum, sent to you, when a doctor diagnoses a covered condition. How much you get depends on the condition, the plan’s percentage for it, and timing rules such as waiting periods and recurrence limits.
The lump sum is the whole point of critical illness insurance. You pick a benefit amount when you buy, such as $10,000 or $20,000. If you are diagnosed with a covered illness, the insurer pays a set share of that amount in one payment. It does not depend on your medical bills, and the money is yours to use.
This page explains how that payment is calculated, when it is reduced, and when a second payment is possible. For the basics of the product, see critical illness insurance. If you are deciding between a lump sum and a per-day hospital benefit, read critical illness insurance vs hospital indemnity.
