definition
A person or asset is considered underinsured when the sum insured (coverage amount) is less than the actual value of the risk or loss. This can result in out-of-pocket expenses during claims.
Underinsurance is common in health insurance, property insurance, and vehicle insurance.
"If your health insurance covers ₹5 lakh but your medical bill is ₹10 lakh, you must pay ₹5 lakh yourself—this is being underinsured."
