Unspecified disorder of kidney and ureter

This code signifies a general, unspecified abnormality or dysfunction affecting either the kidney or the ureter. It indicates that a renal or ureteral issue is present, but the specific nature, etiology, or precise anatomical location of the disorder within these organs has not been definitively diagnosed or documented.

This code is appropriate when documentation indicates a problem with the kidney or ureter, but lacks the specificity required for a more precise diagnosis. It may be used in initial assessments or when diagnostic workup is incomplete, and the provider has not yet identified a more specific condition such as hydronephrosis, calculus, or infection.

• Avoid using this code if more specific documentation is available; always query for greater detail if possible.
• This code should be a last resort when no other specific ICD-9-CM code for a kidney or ureter disorder can be assigned.
• Consider if symptoms (e.g., flank pain, hematuria) are documented, which might lead to a more specific symptom code if no definitive diagnosis is made.
