The role of commercial health insurance characteristics in bariatric surgery utilization.
The goal of this study was to understand relationships among insurance plan type, out-of-pocket cost sharing, and the utilization of bariatric surgery among commercially insured patients. Over 73,000 commercially insured members of the IBM MarketScan commercial claims database who underwent bariatric surgery from 2014-17 were retroactively reviewed. Findings showed that insurance plan types with higher cost sharing have lower utilization of bariatric surgery.

Impact of statewide essential health benefits on utilization of bariatric surgery.
This study looked at the utilization of bariatric surgery after it was included in the Affordable Care Act’s essential health benefits program. The program required individual and small-group insurance plans in 23 states to cover the surgery. Investigators used IBM MarketScan commercial claims data from 2009 to 2016. While bariatric surgery utilization increased in all states after ACA implementation, it was no greater in states with a bariatric surgery essential health benefit. Reasons why can be explored in further studies.

Rates of sialoendoscopy and sialoadenectomy in 5,111 adults with private insurance.
The purpose of this study was to determine frequencies and trends in sialoendoscopy and sialoadenectomy for the treatment of obstructive, non-neoplastic submandibular salivary gland disease. Researchers conducted an epidemiologic study of insurance claims from 2006 to 2013 in a large, private insurance claims database; 5,111 adults with sialadenitis who had a sialoendoscopy or submandibular gland excision were included. The results of this study indicate that the use of sialoendoscopy procedures has increased over time, while the overall rate of sialoadenectomy has decreased, but the authors conclude that both procedures are safe for the treatment of patients with sialadenitis and sialolithiasis.

Effect of insurance expansion on utilization of inpatient surgery.
The researchers examined the differential effect of the Massachusetts insurance expansion on the use of discretionary vs. nondiscretionary surgical procedures. They found that discretionary surgery increased 9.3 percent while nondiscretionary surgery decreased by 4.5 percent. The greatest increase in discretionary surgery was observed for nonwhite participants.

How do coverage policies influence practice patterns, safety, and cost of initial lumbar fusion surgery? A population-based comparison of workers' compensation systems.
In response to increasing use of lumbar fusion for improving back pain, despite unclear efficacy, particularly among injured workers, this study compared the use of complex fusion techniques, adverse outcomes within 3 months, and costs for California and Washington State with workers’ compensation policies that differed in their coverage restrictions. The researchers found that California’s broader coverage policy was associated with more aggressive practice, higher rates of reoperation, readmission and other complications.
