What type of rider provides additional benefits to the insured when they have a pre-existing handicap?

The impairment rider is designed specifically to address situations involving pre-existing conditions or handicaps. When a policyholder has a pre-existing condition, this rider provides additional benefits or coverage that would not typically be included in a standard policy. This could mean that the insurer agrees to cover certain conditions that might otherwise be excluded from coverage due to their pre-existing nature.

The guaranteed insurability rider allows the insured to purchase additional coverage in the future without providing evidence of insurability, which is not relevant to pre-existing conditions. The multiple indemnity rider pays out a multiple of the face amount of the policy in the event of accidental death, providing extra benefits under specific circumstances rather than addressing pre-existing conditions. The waiver of premium rider allows the policyholder to stop paying premiums if they become disabled, but it does not extend additional benefits related to impairments. Thus, the impairment rider is the only option that directly enhances benefits based on existing handicaps.
