Hydronephrosis w ureteral stricture, NEC

This code describes the dilation of the renal pelvis and calyces due to an obstruction in the ureter, specifically caused by a narrowing or stricture of the ureter. This condition leads to urine backup and potential damage to the kidney. It indicates a non-infectious cause of hydronephrosis secondary to a ureteral stricture.

Use this code when documentation clearly states hydronephrosis resulting from a ureteral stricture, and there is no mention of an associated infection. This applies to cases where imaging studies (e.g., ultrasound, CT scan) confirm hydronephrosis and a ureteral stricture is identified as the cause. The physician's diagnostic statement should explicitly link the hydronephrosis to the ureteral stricture.

• Ensure documentation explicitly rules out infection; if infection is present, refer to the Excludes1 note.
• Do not use this code if the ureteral stricture is congenital or due to a specific underlying condition classified elsewhere.
• Verify that the stricture is indeed the cause of the hydronephrosis, not merely co-occurring.
