Critical illness insurance: how the lump sum works and what it covers.

How critical illness coverage works.

You pick a benefit amount, such as $10,000 or $25,000. If you are diagnosed with a covered condition that meets the policy's definition, the insurer pays that amount (or a stated percentage for less severe conditions) directly to you. Many policies pay again for a different covered condition, or for a recurrence after a set period.

The cash is separate from your health plan. It is meant for the costs health insurance does not touch: the deductible and coinsurance, time off work, a spouse's lost income, travel to a specialist center.

Definitions decide everything.

Each covered condition has a written definition. "Heart attack" may require specific test results; "cancer" may exclude early-stage or skin cancers or pay only part of the benefit for them. Before you buy, read the list of conditions, the definitions, and any partial benefits.

• Which conditions are covered, and at what percentage.
• Waiting periods after you buy.
• Pre-existing condition exclusions.
• Whether benefits reduce with age.
• Whether there is a wellness or screening benefit.

Who it fits.

Critical illness coverage fits people with a family history of heart disease, stroke or cancer, sole earners, and anyone on a high-deductible plan with little saved. A lump sum sized to cover your out-of-pocket maximum ($12,000 for one person in 2027) plus a few months of expenses is a common approach.

Supplemental policies are limited-benefit insurance. They pay a fixed cash amount when a covered event happens and are designed to sit alongside major medical coverage, not replace it. They do not count as minimum essential coverage, are not sold on HealthCare.gov, and cannot be paid for with a premium tax credit.
