Abstract

Background: The use of facet joint interventions for spinal pain management increased rapidly between 2000 and 2010, followed by slower growth from 2010 to 2019. Post-COVID analyses demonstrated a marked decline in facet joint interventions despite an increasing prevalence of chronic pain among traditional Medicare beneficiaries after 2019, together with multiple contributing factors over time, including enactment of the Affordable Care Act, COVID-19, the Inflation Reduction Act, and other influences.

Objective: This study aims to update and analyze utilization patterns of facet joint interventions for chronic pain management in the U.S. traditional Medicare population across multiple periods from 2000 to 2024.

Study design: A retrospective cohort study evaluating utilization trends and influencing factors for facet joint interventions in the fee-for-service (FFS) traditional Medicare population in the United States from 2000 to 2024.

Methods: Data were derived from the Centers for Medicare & Medicaid Services (CMS) physician/supplier procedure summary database (2000-2024). Utilization rates per 100,000 Medicare beneficiaries, percentage of change, and geometric average changes were calculated.

Results: Facet joint intervention utilization increased rapidly from 2000 to 2010 (15.5% annually), slowed from 2010 to 2019 (4.2% annually), and declined from 2019 to 2024 (-6.1% annually). Episodes followed similar patterns but declined less steeply than procedures (-6.7% vs. -27.1%). By 2024, service rates had returned to approximately 2012 levels (5,016 vs 5,046 per 100,000 beneficiaries). From 2000 to 2010, lumbar and cervical/thoracic facet joint blocks and radiofrequency ablation procedures increased substantially (13.5%-24.6% annually), followed by slower growth from 2010 to 2019 (2.8%-11.0%), a sharp pandemic-related decline from 2019 to 2020 (10.6%-17.4%), and partial recovery with modest growth or stabilization through 2024. Between 2019 and 2024, the episode ratio of facet joint nerve blocks to radiofrequency ablation declined from 1.9 to 1.7 for lumbar procedures and from 2.4 to 2.0 for cervical procedures, attributed to the mandatory radiofrequency policy. Interventional pain-related specialties accounted for the majority of facet joint procedures, increasing their share from 87.3% in 2010 to 95% by 2024, while surgical specialties declined from 4.8% to 2.0%. During the same period, the site of service shifted modestly from office settings (50.7% to 48.8%) and hospital outpatient departments (HOPD) (declining to 20.5%) toward ambulatory surgery centers (ASCs) (25.6% to 30.6%). These findings reflect increasing specialization, recent reductions in treatment intensity, and the influence of policy changes, Medicare Advantage shifts, and broader system pressures on pain management.

Limitations: The analysis was limited to the FFS traditional Medicare population and data availability through 2024, excluding utilization patterns for Medicare Advantage Plans, which covered 54% of Medicare enrollees in 2024. As with other retrospective claims-based studies, inherent limitations related to coding and administrative data apply.

Conclusion: This retrospective analysis demonstrates a substantial decline in facet joint intervention episodes, with an overall reduction of 6.7% per 100,000 Medicare beneficiaries and an annual decline rate of 1.4% for episodes from 2019 to 2024. In contrast, services or procedures declined more markedly, with an overall reduction of 27.1% and an annual decline rate of 6.1% per 100,000 Medicare beneficiaries.
