CMS has sent several major calendar year 2013 proposed Medicare payment rules to the White House Office of Management and Budget (OMB) for final regulatory clearance. Rules under consideration include the proposed Medicare outpatient hospital, ambulatory surgical center (ASC), end-stage renal disease, and home health prospective payment system rules for calendar year (CY) 2013, along with notices updating payment policies for inpatient rehabilitation facilities and hospices for fiscal year 2013. We also expect the CY 2013 proposed Medicare physician fee schedule rule to reach the OMB shortly. While the text of the regulations are not available at this point, we expect that they will be put on display at the Federal Register in the near future. We will be providing summaries of the rules in future updates.
