Unspecified injury of ureter, sequela

This code signifies a long-term complication or residual effect stemming from a past, unspecified injury to the ureter. It indicates that the acute phase of the ureteral injury has passed, and the patient is now experiencing a chronic condition or lasting consequence directly attributable to that original trauma.

This code is appropriate when documenting a patient presenting with ongoing issues, such as stricture, hydronephrosis, or chronic pain, that are a direct result of a previously sustained, but not specifically defined, ureteral injury. It should be used when the original injury occurred in the past and the current encounter is for the management of its lasting effects.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., N13.0 for hydronephrosis with ureteral stricture).
• Ensure documentation clearly links the current condition to a past ureteral injury, even if the specifics of the original injury are unknown.
• Do not use this code for acute ureteral injuries; instead, refer to the acute injury codes within the S37 category.
