Republican and Democratic lawmakers have agreed on a framework to replace the problematic Medicare payment formula for doctors with a plan that would link reimbursements to the quality of care provided. If successful, the plan could end the annual ?doc fix? debate. The draft released Thursday by the Senate Finance and House Ways and Means committees would eliminate the sustainable growth rate, or SGR, formula. That formula will reduce Medicare doctor payments by nearly 25 percent Jan. 1 unless Congress intervenes.
