In August, CMS published the Final Rule for fiscal year 2020’s IPPS and OPPS code set changes. IPPS updates take effect for discharges occurring from October 1, 2019, through September 30, 2020. OPPS updates go into effect January 1, 2020. Naturally, medical coders are expected to become familiar with the changes and be prepared to assign appropriate codes on or before the effective date. However, the effects of new codes and coding rules reach far beyond an organization’s coding team.
