Democrats plan to submit a “finalized agreement” on allowing Medicare to negotiate prices with pharmaceutical companies to a key Senate official “in the coming days” to see whether it complies with the chamber’s strict budget rules, one of the sources said.

The source, who requested anonymity to discuss sensitive negotiations between Senate Majority Leader Chuck Schumer, D-N.Y., and Sen. Joe Manchin, D-W.Va., described the expected move as “major progress” that shows Democratic leadership wants to “move forward with a bill on the floor as early as next month.”

There’s no final deal on the broader bill, however, as the other major parts of the “reconciliation” package — energy and climate policy provisions and tax changes to raise revenue — are still being negotiated between Schumer and Manchin. Unless an agreement can be reached quickly, it would be difficult to pass the bill before a scheduled monthlong August recess.
