The list of covered critical conditions varies from insurer to insurer, but generally speaking, most comprehensive trauma insurance policies cover approximately 40 medical conditions. Among the standard conditions that will typically be covered are common illnesses and medical events like cancer, heart attack, stroke, and terminal illness. Depending on your policy, you may also be covered for things like Alzheimer's disease, blindness, chronic liver or lung disease, major head trauma, Parkinson's disease, severe burns, and severe diabetes (to name a few). There are also 'partial payments' from some insurers for some conditions that aren't quite as severe too. It's important to read the policy document carefully to ensure you know what's covered and what's not.
