Key Takeaway
Chubb critical illness insurance is a supplemental group plan sold at work through Chubb Workplace Benefits, mostly issued by ACE Property and Casualty Insurance Company, that pays you a cash lump sum when you are diagnosed with a covered condition such as cancer, heart attack or stroke. Combined Insurance, another Chubb company, also markets a critical illness policy to individuals and families.

Chubb is one of the largest insurance groups in the world, but most people meet its critical illness coverage in one place: a payroll deduction offered during open enrollment. The plan pays a set amount of cash straight to you after a covered diagnosis. You decide how to spend it.
This guide breaks down what a Chubb certificate pays for cancer, why two coworkers at different companies can hold very different Chubb plans, how the recurrence rule works and what Chubb sells outside the workplace. Critical illness coverage is supplemental, limited-benefit insurance. It does not pay doctors, it is not major medical coverage and it does not replace health insurance through work, the ACA Marketplace or Medicare.
