Nephroptosis

This code represents nephroptosis, also known as a floating or wandering kidney. It is a condition where a kidney descends more than 2 vertebral bodies or 5 cm when the patient moves from a supine to an upright position. While often asymptomatic, it can cause flank pain, hematuria, or gastrointestinal symptoms due to ureteral kinking or vascular compromise.

Use this code when documentation explicitly states a diagnosis of nephroptosis. This typically occurs after imaging studies (e.g., intravenous pyelogram, renal ultrasound) demonstrate excessive renal mobility. The diagnosis should be made by a physician based on clinical findings and imaging.

• Ensure the documentation clearly specifies "nephroptosis" or "floating kidney."
• Do not confuse this with general kidney displacement if the mobility criteria for nephroptosis are not met.
• Code any associated symptoms (e.g., flank pain, hematuria) separately if documented.
