Other injury of right kidney, sequela

This code signifies a long-term or late-effect complication resulting from a previous injury to the right kidney, other than a contusion, laceration, or unspecified injury. It indicates that the initial injury has healed, but the patient is now experiencing a residual problem directly attributable to that past trauma.

Apply this code when documenting conditions such as chronic renal insufficiency, hydronephrosis, or scar tissue formation in the right kidney, which are a direct consequence of a prior, resolved injury. This code is appropriate when the acute phase of the original injury has passed, and the current encounter addresses the lasting impact.

• Always sequence this code after the code for the specific sequela (e.g., N18.9 for chronic kidney disease).
• Ensure documentation clearly links the current condition to a past right kidney injury.
• This "S" code indicates a sequela and should be used for encounters addressing the late effects of the injury.
