Nonlinear GMM correlation estimates.

This study compares documentation and reimbursement rates before and after provider education in nutritional status documentation. Our study aimed to evaluate accurate documentation of nutrition status between registered dietitian nutritionists and licensed independent practitioners before and after the implementation of a dietitian-led Nutrition-Focused Physical Exam intervention at an academic medical center in the southeastern US. ICD-10 codes identified patients from 10/1/2016-1/31/2018 with malnutrition. The percentage of patients with an appropriate diagnosis of malnutrition and reimbursement outcomes attributed to malnutrition documentation were calculated up to 24 months post-intervention. 528 patients were analyzed. Pre-intervention, 8.64% of patients had accurate documentation compared to 46.3% post-intervention. Post-intervention, 68 encounters coded for malnutrition resulted in an estimated $571,281 of additional reimbursement, sustained at 6, 12, 18, and 24 months. A multidisciplinary intervention improved physician documentation accuracy of malnutrition status and increased reimbursement rates.
