Renal dysplasia

This code represents abnormal development of the kidney tissue, characterized by disorganized renal parenchyma, often with cysts and immature collecting ducts. It is a congenital malformation that can affect one or both kidneys, leading to impaired renal function.

Use this code when documentation explicitly states "renal dysplasia" or describes the characteristic histological findings of disorganized renal development. This diagnosis is typically made in infancy or childhood, often following imaging studies or biopsy.

• Differentiate from polycystic kidney disease; the Excludes1 note is critical.
• Ensure documentation specifies "dysplasia" rather than general kidney malformation.
• Consider laterality if specified (e.g., unilateral vs. bilateral), though this code does not differentiate.
