WHAT IT DOES

What the bill would do, and why it matters

BASED ON THE TEXT AS INTRODUCED
tl;drWRITTEN OCT 4 FROM THE TEXT AS INTRODUCED

Medicare negotiates prices for certain prescription drugs, including biologic medicines. This bill would give some reference biologic drugs up to two years more before Medicare negotiation when a biosimilar is expected to enter the market. If the biosimilar does not reach the market within the specified period, the reference drug's manufacturer would owe rebates.

  • INTRODUCED ONLY This bill has been introduced and possibly referred to a committee, but it has not passed any vote. Most introduced bills never become law — they die in committee without a hearing.
  • DATA NOTE No Congressional Research Service summary was available.
WHAT IT WOULD DO · 4 PROVISIONSINTRODUCED IN HOUSE
  1. Extend delays for biosimilar entry

    The bill would allow a delay of up to two years in Medicare price negotiation when a biosimilar is expected to reach the market. A delay could be granted on request based on clear and convincing evidence, or automatically when specified development steps have occurred and the manufacturer expects to market the biosimilar within the two-year period.

  2. Require manufacturers to confirm information

    Before relying on information to grant a delay, the Secretary of Health and Human Services would have to share that information with the biosimilar manufacturer and require it to confirm or correct the information in writing under penalty of perjury. Pending or prospective patent litigation would not by itself prevent a delay.

  3. Require rebates if a biosimilar does not launch

    If a biosimilar is not licensed and marketed by the specified two-year point, the reference product would be added to the Medicare negotiation list for a later year, and its manufacturer would owe rebates for the delayed period. The rebate calculation would use 75 percent of the specified price difference for Part D and 80 percent for Part B.

  4. Apply changes beginning in 2027

    The changes would apply to initial price applicability years beginning with 2027.

THE CONTEXT

The bill would change how the timing of Medicare price negotiation is tied to the expected arrival of a competing biosimilar. The practical stakes are when Medicare's negotiated price applies and whether the reference drug manufacturer owes rebates if the expected competition does not reach the market in time.
