What type of policy feature allows for increased coverage in the event of serious illness?

The type of policy feature that allows for increased coverage in the event of serious illness is the living benefit rider. This rider provides policyholders with the ability to access a portion of their life insurance benefit while they are still alive, specifically in circumstances involving terminal illness or chronic conditions. It is designed to offer financial support during challenging times, which can be crucial for expenses related to treatment or end-of-life care.

This coverage allows individuals to maintain their quality of life during serious health challenges and eases the financial burden of medical costs. Living benefit riders enhance a life insurance policy's value by providing additional liquidity when it is most needed, highlighting the policy's flexibility in addressing unforeseen health crises.
