A headline in the Notes From Annapolis column in yesterday's edition's of The Sun incorrectly referred to Medicare, when the story was about the state Medicaid program. The article also may incorrectly have led to the conclusion that doctors billing the state twice the amount they are now allowed to bill might actually get paid more. In fact, the higher billing to the state is designed to leverage a greater federal reimbursement to the state. The doctors' share of the reimbursement will not increase.
