WASHINGTON (AP) — A new $56,000-a-year Alzheimer’s medication that’s leading to one of the biggest increases ever in Medicare premiums is highlighting the limitations of President Joe Biden’s strategy for curbing prescription drug costs. The medication known as Aduhelm would be protected from Medicare price negotiations for more than a decade under the Democratic drug pricing compromise before Congress. That’s because the bill doesn’t allow Medicare to negotiate over newly launched drugs. Seniors soon will be paying higher premiums so Medicare can set aside a contingency fund for Aduhelm. Medicare’s Part B premium will jump by $21.60 a month next year, to $170.10.
