What type of insurance coverage allows the insured to purchase more insurance after a specific period of time?

The type of insurance coverage that allows the insured to purchase more insurance after a specific period of time is known as "guaranteed insurability" or "guaranteed purchase option" coverage. This provision is typically found in life insurance policies and some health insurance plans, enabling policyholders to increase their coverage without undergoing additional medical underwriting. This feature is beneficial for individuals who anticipate changes in their insurance needs due to life events such as marriage, the birth of a child, or increased financial responsibilities.
