The document discusses changes to Medicare reimbursement policies in 2022 related to inpatient procedures. Specifically, it summarizes that CMS reversed its previous phase out of the Inpatient-Only (IPO) list, which designates certain complex procedures that must be performed in an inpatient setting to receive reimbursement. Reinstating the IPO list provides several benefits, including improved patient safety, increased reimbursement for hospitals that perform many IPO procedures, and reduced burden on physicians. Hospitals are advised to prepare for potential increases in inpatient volumes and coding needs resulting from the IPO list changes.
