ICD Code N13.3 is a non-billable code. To code a diagnosis of this type, you must use one of the two child codes of N13.3 that describes the diagnosis 'other and unspecified hydronephrosis' in more detail.

The ICD code N133 is used to code Hydronephrosis

Hydronephrosis — literally "water inside the kidney" — refers to distension and dilation of the renal pelvis and calyces, usually caused by obstruction of the free flow of urine from the kidney. Untreated, it leads to progressive atrophy of the kidney. In cases of hydroureteronephrosis, there is distention of both the ureter and the renal pelvis and calices.

Specialty: Urology, Nephrology
MeSH Code: D006869
ICD 9 Code: 591

Specimen of a kidney that has undergone extensive dilation due to hydronephrosis. Note the extensive atrophy and thinning of the renal cortex.
