Anticipating Aduhelm's costs, Medicare plans big jump in premiums

Premiums and deductibles in one part of Medicare will rise by 15% in 2022 as the federal program for elderly and disabled people prepares for the possibility that the cost of Biogen's controversial Alzheimer's drug Aduhelm will push up spending. The $21.60-a-month increase to premiums is the largest ever in the program's history, according to the AARP.
