Currently in the United States, Medicare will not approve a power wheelchair for persons who do not need to use the chair "inside their own home", even if their medical needs restrict the use of a mobility scooter. For example, a person with severe arthritis of both shoulders and hands may not be the best candidate for a scooter, but because they can walk a few steps in their own home, such persons are not seen as approved candidates for a power wheelchair either. Various disability rights groups are campaigning for Medicare to change this policy. For those who do qualify for Medicare, they can reimburse up to 80% of the Medicare allowable value of the scooter.
