Critical illness and hospital indemnity insurance: the supplemental cash policies

Supplemental health policies — critical illness insurance and hospital indemnity insurance — get pitched at open enrollment as a cushion for the costs your main health plan doesn't cover. They pay cash directly to you (not to providers) when a covered event happens, and you can spend it on anything: deductibles, rent, groceries, travel to treatment. They are genuinely useful in specific situations and genuinely oversold in others. The distinction comes down to what gap you're actually filling.

What each one does

• Critical illness insurance: pays a lump sum (say $10,000-$50,000) upon diagnosis of a covered serious condition — commonly heart attack, stroke, cancer, kidney failure. The cash is yours to use however you like.
• Hospital indemnity insurance: pays a fixed cash amount per day (or per admission) that you're hospitalized, regardless of the actual bill.
• Both pay in addition to your regular health insurance — they don't coordinate with or replace it.
• Both have covered-condition lists and exclusions; a diagnosis or stay outside the definitions pays nothing, so the fine print is the product.

The honest limits

• They are not a substitute for comprehensive health insurance — they pay narrow, defined benefits, not your actual medical bills.
• Covered-condition definitions can be strict: a 'heart attack' or 'cancer' may need to meet specific clinical criteria to trigger payment.
• Like other narrow products, their loss ratios can be modest — a chunk of premium goes to overhead, so the expected payout is often less than premiums for most buyers.
• Pre-existing conditions are frequently excluded, and benefits may be reduced or waived for conditions you already have.

The bottom line

Critical illness and hospital indemnity insurance pay you cash — not your providers — when a covered diagnosis or hospital stay hits, on top of your regular coverage. They earn their keep mainly as a bridge over a high deductible for people who'd struggle to cover that gap from savings. If a low-deductible plan or a solid emergency fund already caps your exposure, they mostly duplicate protection you have. Read the covered-condition definitions closely, treat them as supplements rather than health insurance, and buy only the specific gap you can't otherwise absorb.
