ICD Code N13.4

ICD code N13.4 is hydroureter, which refers to the swelling or dilation of the ureter due to a buildup of urine, often caused by an obstruction or blockage.

1. Evidence of ureteral dilation on imaging studies (e.g., ultrasound, CT, MRI)

2. Presence of urinary tract obstruction or impaired urine flow

3. Symptoms such as flank pain, abdominal pain, or urinary frequency

4. Associated findings of hydronephrosis or renal pelvis dilation

5. Exclusion of congenital causes in adult patients

6. Identification of underlying causes such as stones, strictures, tumors, or external compression

7. Absence of infection as the primary diagnosis (unless secondary to obstruction)
