In simple words: An ectopic kidney means that one or both kidneys are not in their usual place in the body.This is a condition present from birth and might cause problems with kidney function later in life.

Q63.2, Ectopic kidney, signifies a congenital anomaly characterized by the presence of one or both kidneys in an abnormal location.This malposition can range from slightly displaced to significantly ectopic, potentially impacting renal function and increasing the risk of complications such as urinary tract infections, hydronephrosis, and renal calculi.The ectopic kidney may be located anywhere along the normal migratory pathway, including the pelvis, abdomen, or even the thorax.Thorough clinical evaluation, including imaging studies like ultrasound, CT scan, or MRI, is essential for accurate diagnosis and management.

Example 1: A newborn infant presents with an abdominal mass, identified on physical examination as an ectopic kidney.Ultrasound confirms the diagnosis, and the infant is monitored for potential complications., A young adult experiences recurrent urinary tract infections.Imaging reveals a pelvic ectopic kidney with partial obstruction of the ureter, requiring surgical intervention., An adult undergoes imaging for unrelated reasons and incidentally discovers an ectopic kidney.The kidney is functionally normal, and no intervention is needed, but regular monitoring is recommended.

Complete history and physical examination, including any symptoms related to renal function or location. Imaging studies such as ultrasound, CT scan, or MRI confirming the diagnosis and specifying the location and any associated anomalies.Relevant laboratory tests assessing renal function.Documentation of any interventions or follow-up care.

** Further sub-classification may be needed to specify the location (e.g., pelvic, thoracic) and laterality (unilateral, bilateral) of the ectopic kidney.Consider using additional ICD-10 codes to capture any associated malformations or complications.
