Abnormal radiologic findings on dx imaging of r kidney

This code indicates the presence of an unexpected or unusual finding identified during a radiological examination (e.g., X-ray, CT, MRI, ultrasound) of the right kidney. These findings are not definitive diagnoses but rather observations that deviate from normal anatomy or expected appearance, requiring further investigation or clinical correlation. It suggests an abnormality without specifying the underlying pathology.

Use this code when diagnostic imaging of the right kidney reveals an abnormal finding (e.g., mass, cyst, hydronephrosis, calculus, or structural anomaly) that is not yet definitively diagnosed. This code is appropriate when the radiologist's report describes an abnormality but the physician has not yet established a specific diagnosis. Documentation should clearly state "abnormal findings" or similar language related to the right kidney on imaging.

• Do not use this code if a definitive diagnosis for the abnormal finding has been established (e.g., N20.0 for calculus of kidney).
• Always sequence this code after any definitive diagnosis if one is known and the abnormal finding is a manifestation of that diagnosis.
• Ensure the imaging report explicitly states the abnormality is located in the right kidney; otherwise, consider R93.429 for unspecified kidney.
