Oth disorders of kidney and ureter in diseases classd elswhr

This code represents kidney and ureter conditions that are secondary manifestations of another underlying disease process, not primarily originating within the renal or urinary system itself. It signifies renal or ureteral involvement where the primary pathology is classified elsewhere in the ICD-10-CM system.

Use this code when documentation clearly links a kidney or ureter disorder to an external, underlying systemic disease. Examples include renal complications arising from conditions like diabetes, autoimmune disorders, or certain infectious diseases, where the primary disease is coded first. Ensure the physician explicitly states the kidney/ureter disorder is "due to" or "manifestation of" the primary condition.

• Always sequence the underlying systemic disease code first, followed by this code to indicate the renal/ureteral manifestation.
• Carefully review the "Excludes1" notes to avoid co-coding with specific infectious or metabolic conditions that have their own designated kidney/ureter manifestation codes.
• Do not use this code for primary kidney or ureter diseases; those conditions have specific codes within Chapter 14 (N00-N39).
