This regulation was adopted to correct technical and typographic errors identified in a final rule published November 24, 2010, titled “Medicare Program: Hospital Outpatient Prospective Payment System and CY 2011 Payment Rates; Ambulatory Surgical Center Payment System and CY 2011 Payment Rates; Payments to Hospitals for Graduate Medical Education Costs; Physician Self-Referral Rules and Related Changes to Provider Agreement Regulations; Payment for Certified Registered Nurse Anesthetist Services Furnished in Rural Hospitals and Critical Access Hospitals.” The errors were found in the preamble and addenda B, AA and BB of the November 2010 final rule. The new regulation also incorporates changes to the Medicare Physician Fee Schedule (MPFS) for CY 2011, which appeared in a January 11, 2011, CY 2011 MPFS correction notice. The corrections are effective January 1, 2011, as if they were initially included in the November final rule.
