Disorder of kidney and ureter, unspecified

This code represents a general, unspecified abnormality affecting either the kidney or the ureter. It indicates that a disorder exists within these organs, but the specific nature, cause, or precise location of the condition has not been definitively diagnosed or documented.

Use this code when documentation indicates a kidney or ureteral disorder without further specificity, such as "renal disorder" or "ureteral abnormality," and no more precise ICD-10-CM code is available. It is appropriate when the provider has not yet determined the exact diagnosis or when the available clinical information is insufficient for a more specific code.

• Avoid using this code if a more specific diagnosis for the kidney or ureter is documented (e.g., calculus, infection, hydronephrosis).
• Ensure documentation clearly states a disorder of the kidney or ureter, even if unspecified.
• Review "Excludes1" notes carefully; never code this with chronic renal insufficiency (N18.9) or unspecified nephritic syndrome (N05.-).
