Other specified disorders of kidney and ureter

This code signifies a renal or ureteral disorder that is not specifically classified elsewhere within the N28 category. It encompasses a range of less common or ill-defined conditions affecting the kidney or ureter, excluding those with more precise ICD-10-CM codes. This includes various structural anomalies, functional impairments, or inflammatory processes not meeting criteria for other specified diagnoses.

Use this code when documentation clearly indicates a disorder of the kidney or ureter that does not have a more specific ICD-10-CM code. This often applies to conditions like certain congenital anomalies, acquired deformities, or unspecified functional disturbances of these organs. Supporting documentation should detail the specific nature of the disorder, even if it lacks a dedicated code.

• Always review the entire N28 category and other relevant renal/ureteral codes (e.g., N10-N16 for tubulo-interstitial diseases) before assigning this unspecified code.
• Ensure the medical record explicitly states the condition affects the kidney or ureter and is not better described by a more specific diagnosis.
• Avoid using this code if a more precise "unspecified" code exists for the documented condition (e.g., N28.9 for unspecified disorder of kidney and ureter).
