The strongest CDI query opportunity is clarifying whether the UTI iscatheter-associated. The patient has anindwelling Foley catheter, significant leukocytosis (WBC 20), apositive urine culture for E. coli, and is being treated with antibiotics for UTI—these indicators raise a clear question about theetiology of infectionand whether it is related to the urinary catheter. In outpatient CDI practice, linking the infection to a device (when clinically supported) improves documentation accuracy, supports correct code assignment, and has important quality and compliance implications because catheter-associated UTIs are captured differently than uncomplicated UTIs. By comparison, querying the “etiology of BPH” is not supported as an immediate gap (BPH is already stated), and the “etiology of low back pain” is less directly tied to the documented treatment focus (UTI management). “Leukocytosis” is a lab finding that is already objectively supported and often represents a symptom/abnormal result rather than the principal clarification needed. Therefore, confirming whether the UTI is related to the Foley catheter is the best, most clinically anchored query.
