Abstract

Background

Despite total shoulder arthroplasty (TSA) and reverse TSA (rTSA) being fundamentally different procedures, and indicated in different pathologies (rTSA for rotator cuff deficiency [RCD] and proximal humeral fractures [PHFx] and anatomic TSA [aTSA] for glenohumeral osteoarthritis [GHOA]), they have the same Current Procedural Terminology (CPT) code (23472). This paper’s aim is to investigate differences in operative time and work-related value units (wRVUs) per hour among these pathologies, and ultimately determine if there is a need to assign separate CPTs for aTSA and rTSA.

Methods

A retrospective cohort of data from the American College of Surgeons–National Surgical Quality Improvement Program was collected, all patients who underwent aTSA or rTSA (CPT: 23472) between the years of 2006 and 2019 for diagnoses of GHOA, RCD, and PHFx were included. Data collected included patient age, body mass index, operative time, and wRVUs per hour.

Results

Compared to GHOA (reference group), the average operative time for the RCD cohort was 12.242 minutes shorter (P < .001), while the wRVUs were higher by 1.627 (P < .001). The average operative time for rTSAs in the PHFx cohort were 17.615 minutes longer (P < .001), while the wRVUs were lower by 2.205 (P < .001).

Conclusion

The average operative time for rTSAs for both RCDs and PHFx were longer than that for aTSAs for GHOA. Additionally, wRVUs were lower for rTSAs for RCD and PHFx compared to aTSAs for GHOA. This elucidates inconsistency in reimbursement structure for the procedures, which should be revisited.
