Low-Back Pain-Related Healthcare Utilization Patterns for Upper and Lower Extremity Amputees

The goal of this study is to identify and develop a syntax of ICD (diagnosis) and CPT (procedures) codes that are able to accurately identify amputees in the MHS, and all LBP-related care, describe and characterize the amputee patient population with low back pain, and calculate the total 1-year LBP-related costs in the year following the initial index visit for LBP.
