Abstract
Study design: Retrospective database study.
Objective: To leverage a commercial insurance claims database to explore trends in laminoplasty utilization and reimbursement in the United States. Secondarily, volume estimates were compared with data from the industry and from the Centers for Medicare and Medicaid (CMS).
Summary of background data: With purported benefits of motion preservation and lower complication rates than fusion, cervical laminoplasty is an important surgical technique. However, current commercial database studies suggest that laminoplasty adoption in the United States has been slow.
Methods: The primary outcome was the total volume of laminoplasty procedures performed in the United States per year. Truven, a large commercial insurance claims database, was used to estimate laminoplasty volume from 2009 to 2019. Volume estimates for posterior cervical fusions were also generated as a comparator. Reimbursement data for laminoplasty adjusted for inflation were also generated. Trends in national procedural volumes and reimbursement over time were assessed with the Pearson correlation test. CMS Part B national summary statistics from 2000 to 2022 and market data from laminoplasty device manufacturers from 2017 to 2024 were qualitatively compared with volume estimates from Truven.
Results: Truven volume of laminoplasty remained stable throughout the study period with an estimated annual volume of 944-1590 cases. Posterior cervical fusion volume was much higher, ranging from 7930 to 11,874 cases with increased trend. When compared qualitatively, Truven volume estimates were similar to those from CMS data, although industry volume estimates were comparatively higher (estimated total volume of 8352-11,428 cases). There was no statistically significant trend in Truven reimbursement values for laminoplasty from 2009 to 2019.
Conclusions: Industry market data suggest more laminoplasty procedures are being performed nationally than what is estimated by commercial/CMS databases. This suggests possible growth in laminoplasty usage, given purported advantages to fusion in the properly indicated patient, and possibly calls into question the epidemiological accuracy of commercial claims databases.
期刊介绍：
Clinical Spine Surgery is the ideal journal for the busy practicing spine surgeon or trainee, as it is the only journal necessary to keep up to date with new clinical research and surgical techniques. Readers get to watch leaders in the field debate controversial topics in a new controversies section, and gain access to evidence-based reviews of important pathologies in the systematic reviews section. The journal features a surgical technique complete with a video, and a tips and tricks section that allows surgeons to review the important steps prior to a complex procedure.
Clinical Spine Surgery provides readers with primary research studies, specifically level 1, 2 and 3 studies, ensuring that articles that may actually change a surgeon’s practice will be read and published. Each issue includes a brief article that will help a surgeon better understand the business of healthcare, as well as an article that will help a surgeon understand how to interpret increasingly complex research methodology. Clinical Spine Surgery is your single source for up-to-date, evidence-based recommendations for spine care.
