Other specified anomalies of kidney

This code signifies various congenital malformations of the kidney that are not specifically classified elsewhere. These anomalies can include conditions like renal hypoplasia (underdevelopment), renal dysplasia (abnormal tissue development), or other structural defects present at birth. It encompasses a range of developmental abnormalities affecting kidney size, shape, or internal architecture.

Use this code when documentation specifies a congenital anomaly of the kidney that doesn't fit a more precise ICD-9-CM code, such as agenesis or polycystic kidney disease. This code is appropriate for conditions like unilateral small kidney, multicystic dysplastic kidney (MCDK) when not specified as polycystic, or other non-specific developmental defects. Documentation should clearly state a congenital renal anomaly.

• Ensure the documentation explicitly states a congenital anomaly of the kidney.
• Always review for more specific codes first (e.g., renal agenesis, polycystic kidney disease) before resorting to this "other specified" category.
• If the anomaly is acquired rather than congenital, a different code from the acquired conditions of the genitourinary system would be more appropriate.
