This retrospective cross-sectional study focused on patients who were 65 years and older who have Medicare and an ICD10 code of obesity. The study uses archival billing data from the 2017 Medicare 5% Limited Data Set to examine use of bariatric surgery. This study examined the different characteristics (geographic region, age, sex, co-morbidities) for all patients with a BMI greater than 40 who had bariatric surgery in 2017 compared to patients with a BMI greater than 40 who did not receive a surgical intervention. Results found that patients who are female are associated with higher odds of receiving bariatric surgery. Patients who are older, dual eligible for Medicare and Medicaid, or have a diagnosis of diabetes with complications are associated with lower odds of receiving bariatric surgery. The results of this study should be used to target patients over the age 65, have a diagnosis of obesity, and are considering making healthy lifestyle change with bariatric surgery or other healthy options.
