Number of Weight Loss Surgeries Performed in California Hospitals

The dataset contains the number for five types of weight loss (bariatric) surgeries (Open Roux-en-Y gastric bypass, laparoscopic Roux-en-Y gastric bypass , laparoscopic adjustable gastric banding, vertical sleeve gastrectomy , and biliopancreatic diversion ) performed in California hospitals. The 2015 Data are reported for January-September due to coding changes from ICD-9-CM to ICD-10-CM/PCS, which began October 1, 2015. Caution should be taken before making comparisons across years since previous years' results are based on 12 months of data, while results for year 2015 are based on 9 months of data. This dataset does not include surgeries performed in outpatient settings.
