Trauma insurance typically covers 30-60 serious medical conditions, with policies varying between insurers. The four main conditions accounting for approximately 90% of claims are: cancer (excluding specified early-stage cancers), heart attack with evidence of severe heart muscle damage, stroke resulting in specified permanent impairment, and coronary artery bypass surgery through open chest. Other commonly covered conditions include major organ transplant, kidney failure requiring dialysis, multiple sclerosis, paralysis, severe burns, loss of limbs, benign brain tumour, motor neurone disease, Parkinson's disease, blindness, deafness, and loss of speech. Since July 2017, Australian insurers use industry-approved standard definitions for at least the three main conditions (cancer, heart attack, and stroke) as set by the Financial Services Council. However, it's crucial to read your specific Product Disclosure Statement (PDS) as coverage and medical definitions can differ significantly between insurers and policies.
