Abstract
Objectives: Despite lack of nationwide Medicare Coverage by the Centers for Medicare and Medicaid Services, the utilization of cervical disc arthroplasty (CDA) has risen in popularity. The purpose was to compare primary and revision cervical disc arthroplasty (CDA) from 2010 to 2020 with respect to: 1) utilization trends, 2) patient demographics; and 3) healthcare reimbursements.
Methods: Using the PearlDiver database, we studied patients undergoing primary and revision CDA for degenerative cervical disc pathology from 2010 to 2020. Endpoints of the study were to compare patient demographics (including Elixhauser Comorbidity Index (ECI)), annual utilization trends, lengths of stay (LOS), and reimbursements. Chi-square analyses compared patient demographics. T-tests compared LOS and reimbursements. A linear regression was used to evaluate for trends in procedural volume over time. P values <0.05 were statistically significant.
Results: In total, 15,306 patients underwent primary (n= 14,711) or revision CDA (n= 595). Patients undergoing revisions had a greater comorbidity burden (mean ECI= 4.16 vs 2.91; p<0.0001). From 2010 to 2020, primary CDA utilization increased by 413% (447 vs 2297 procedures; p<0.001); comparatively revision CDA utilization increased by 141% (32 vs 77 procedures; p<0.001). Mean LOS were greater for revision cases (1.37 vs 3.30 days, p<0.001). Reimbursements for revisions were higher on the day of surgery ($5,585 vs $13,692) and within 90 days of surgery ($7,031 vs $19,340), all p<0.0001.
Conclusions: There is a high rate of annual growth in CDA utilization and revision CDA in the United States. Reimbursements for revision CDA were more than double primary cases.
