BACKGROUND: The cost of US health care continues to increase, with treatments related to low back and neck pain and other musculoskeletal disorders accounting for the third highest amount of various disease categories. Interventional techniques for managing pain apart from conservative modalities and surgical interventions, have generally been thought to be growing rapidly. However, a recent analysis of utilization of interventional techniques from 2000 to 2016 has shown a modest decline from 2009 to 2016, compared to 2000 to 2009.

OBJECTIVES: The objectives of this analysis include providing an update on utilization of interventional techniques in managing chronic pain in the Medicare population from 2009 to 2018 in the fee-for-service (FFS) Medicare population of the United States.

STUDY DESIGN: Utilization patterns and variables of interventional techniques in managing chronic pain were assessed from 2000 to 2009 and from 2009 to 2018 in the FFS Medicare population of the United States.

METHODS: The data for the analysis was obtained from the master database from the Centers for Medicare & Medicaid Services (CMS) physician/supplier procedure summary from 2000 to 2018.

RESULTS: The analysis of data showed that there was a decline in utilization of interventional techniques from 2009 to 2018 of 6.7%, with an annual decline of 0.8% per 100,000 FFS Medicare population, despite an increase of 0.7% per year of population growth (3.2% of those 65 years or older) and a 3% annual increase in Medicare participation from 2009 to 2018. Medicare data from 2000 to 2009 showed an increase of 11.8% per year per 100,000 individuals of the Medicare population. The 2009 to 2018 data also showed a 2.6% annual decrease in the rate of utilization of epidural and adhesiolysis procedures per 100,000 population of FFS Medicare, and a 1% decrease for disc procedures and other types of nerve blocks, while there was an increase of 0.9% annually for facet joint interventions and sacroiliac joint blocks.

LIMITATIONS: Limitations of this analysis include: only the Medicare population was utilized, and among the Medicare population, only the FFS population was evaluated; utilization patterns in Medicare Advantage Plans, which constitutes almost 30% of the population were not considered. Further, the utilization data for individual states was sparse and may not be accurate.

CONCLUSION: The decline in utilization of interventional techniques continued from 2009 to 2018 with 6.7% per 100,000 Medicare population, with an annual decline of 0.8%, despite an increase in the population rate and Medicare enrollees of 0.7% and 3% annually.
