In the final rule regarding the Medicare hospital outpatient prospective payment system (OPPS) for calendar year 2010, the Centers for Medicare & Medicaid Services (CMS) adopted several significant changes to its policies on physician supervision of hospital outpatient services (74 Fed. Reg. 60316 [November 20, 2009]). These changes were made in response to strongly negative reactions of hospitals to CMS “clarifications” regarding these supervision requirements in the OPPS rule for calendar year 2009 and in Medicare Manual provisions.
