Abstract
- Objective:To evaluate the positive predictive value of claims-based V85 codes for identifying individuals with varying degrees of BMI relative to their measured BMI obtained from medical record abstraction. Methods:This was a retrospective validation study utilizing administrative claims and medical chart data from 1 January 2009 to 31 August 2015. Randomly selected samples of patients enrolled in a Medicare Advantage Prescription Drug (MAPD) or commercial health plan and with a V85 claim were identified. The claims-based BMI category (underweight, normal weight, overweight, obese class I–III) was determined via corresponding V85 codes and compared to the BMI category derived from chart abstracted height, weight and/or BMI. The positive predictive values (PPVs) of the claims-based BMI categories were calculated with the corresponding 95% confidence intervals (CIs). Results:The overall PPVs (95% CIs) in the MAPD and commercial samples were 90.3% (86.3%–94.4%) and 91.1% (87.3%–94.9%), respectively. In each BMI category, the PPVs (95% CIs) for the MAPD and commercial samples, respectively, were: underweight, 71.0% (55.0%–87.0%) and 75.9% (60.3%–91.4%); normal, 93.8% (85.4%–100%) and 87.8% (77.8%–97.8%); overweight, 97.4% (92.5%–100%) and 93.5% (84.9%–100%); obese class I, 96.9 (90.9%–100%) and 97.2% (91.9%–100%); obese class II, 97.0% (91.1%–100%) and 93.0% (85.4%–100%); and obese class III, 85.0% (73.3%–96.1%) and 97.1% (91.4%–100%). Conclusions:BMI categories derived from administrative claims, when available, can be used successfully particularly in the context of obesity research. [ABSTRACT FROM PUBLISHER]
