2025 ICD-10-CM code N13.4

Hydroureter.A condition characterized by dilation of the ureter.

Code N13.4 should be used when the primary diagnosis is hydroureter without any associated infection. If infection is present, N13.6 (Pyonephrosis) should be used.Congenital hydroureter is classified under Q62.3.

Medical necessity for treatment of hydroureter is established by the presence of symptoms, the severity of the dilation, and the potential for complications such as kidney damage or infection. Treatment aims to relieve the obstruction, restore normal urine flow, and prevent further complications.

Diagnosis and management of hydroureter typically falls under the purview of urologists or nephrologists. They are responsible for determining the underlying cause, assessing the severity, and recommending appropriate treatment.

In simple words: Hydroureter is a condition where the tube that carries urine from your kidney to your bladder becomes swollen.

Hydroureter is the distension of the ureter, the tube that carries urine from the kidney to the bladder. This condition can be caused by various factors, including blockage, anatomical abnormalities, or functional issues.

Example 1: A patient presents with flank pain and difficulty urinating. Imaging studies reveal a blockage in the ureter causing hydroureter., A pregnant woman experiences hydroureter due to compression of the ureter by the enlarging uterus., A patient with a history of kidney stones develops hydroureter due to a stone lodged in the ureter.

Documentation should include details of the patient's symptoms, relevant medical history, imaging findings confirming the dilation of the ureter, and the identified cause of the hydroureter.Any associated infections or complications should also be documented.
