599.0
ICD-9-CMThis code signifies an infection affecting any part of the urinary system (kidneys, ureters, bladder, or urethra) where the specific anatomical location of the infection has not been documented by the provider. It indicates the presence of an infection within the urinary tract without further specificity regarding its origin or extent.
This code is appropriate when the physician's documentation clearly states "urinary tract infection" or "UTI" without specifying if it's cystitis, pyelonephritis, urethritis, etc. It is used when the clinical picture points to a urinary infection, but the exact site is undetermined or not yet diagnosed.
