The Centers for Medicare & Medicaid Services (CMS) has sent several final Medicare calendar year 2013 payment rules to the White House Office of Management and Budget (OMB) for final regulatory clearance. Rules under review will establish final 2013 payment and other policies under the Medicare physician fee schedule, hospital outpatient prospective payment system,, home health prospective payment system (PPS), and end-stage renal disease PPS. Copies of the rules are not available at this point, but they are expected to go on display at the Federal Register in the coming days.
