Nephroptosis

This code represents nephroptosis, a condition where the kidney descends more than two vertebral bodies or 5 cm when the patient moves from a supine to an upright position. It is also known as a "floating kidney" and can be asymptomatic or cause flank pain, hematuria, or gastrointestinal symptoms.

Use this code when documentation clearly indicates a diagnosis of nephroptosis, often identified through imaging studies like intravenous pyelogram (IVP) or renal ultrasound performed in both supine and upright positions. It is appropriate for cases where the kidney exhibits abnormal mobility or displacement.

• Ensure documentation specifies "nephroptosis" or "floating kidney" and not just general kidney displacement without the characteristic mobility.
• Do not confuse with other kidney malpositions or ectopia, which have different ICD-9-CM codes.
• Sequence as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is an co-existing condition impacting care.
