Seniors Paid Billions in Extra Premiums Due to Alleged Medicare Overpayments

The average American senior's Medicare premiums last year were about 10% higher, or more than $200 annually, because of alleged overpayments to private Medicare Advantage plans, congressional investigators found.

Medicare Part B premiums that most seniors pay were partly pushed up by controversial health-insurer practices such as adding diagnoses to trigger higher payments, according to the Joint Economic Committee, a bipartisan group of lawmakers that advises Congress on financial matters.
