On December 14, 2017, the Centers for Medicare & Medicaid republished the final rule with comment period for the Medicare hospital outpatient prospective payment system (OPPS) and the Medicare ambulatory surgical center (ASC) payment system for CY 2018 (“Final Rule”). The republication included an editorial note stating that the Final Rule was originally published in the federal register on November 13, 2017 but that publication omitted a section of the document due to a printing error. Instead of publishing only the missing section, CMS republished the Final Rule in its entirety. The Final Rule retains the January 1, 2018 effective date and the December 31, 2017 deadline for submitting comments.
