Claims-Based Reporting of Post-Operative Visits for Procedures with 10- or 90-Day Global Periods: Updated Results Using Calendar Year 2018 Data.

Medicare payments for most surgical procedures cover both procedures and post-operative visits occurring within a global period of either ten or 90 days following procedures. There have been concerns that fewer post-operative visits are provided than the number of post-operative visits considered when the procedure was valued. To help inform accurate valuation of procedures with global periods, the Centers for Medicare & Medicaid Services (CMS) required select practitioners to report on post-operative visits after select procedures with 10- or 90-day global periods. The authors of this article summarize patterns of post-operative visits for procedures furnished during calendar year 2018, building on prior research that analyzed data for procedures with July 1, 2017, through June 30, 2018, service dates. During calendar year 2018, 96.5 percent of procedures with 10-day global periods did not have an associated post-operative visit. Approximately two-thirds of procedures with 90-day global periods had an associated post-operative visit; however, the ratio of observed to expected post-operative visits provided for 90-day global period procedures was only 0.38. Underreporting of post-operative visits might be driving these low rates. However, in sensitivity analyses limited to practitioners who were actively reporting their post-operative visits, post-operative patterns were largely similar to the main analysis. Collectively, these findings suggest that a large share of expected post-operative visits are not delivered, and that underreporting is unlikely to fully explain the low ratio of expected post-operative visits provided.
