Congenital malformation of kidney, unspecified

This code signifies a birth defect affecting the kidney where the specific type of malformation is not documented or known. It indicates an abnormality in the kidney's structure or development present at birth, without further detail regarding its nature.

Use this code when a congenital kidney malformation is identified, but the medical record lacks specificity regarding the exact type of anomaly (e.g., agenesis, hypoplasia, dysplasia, polycystic kidney disease). This code is appropriate when documentation only states "congenital kidney malformation" or "renal anomaly, unspecified."

• Avoid using this code if more specific documentation is available; query the provider for clarification.
• Do not use for acquired kidney conditions or when the laterality of the malformation is specified (e.g., Q63.0-Q63.8).
• Sequence as a primary diagnosis when the congenital malformation is the reason for the encounter, or as a secondary diagnosis if it's an incidental finding or comorbidity.
