Other injury of unspecified kidney, sequela

This code signifies a long-term or late-effect complication resulting from a past, unspecified injury to a kidney. It indicates that the initial kidney trauma has resolved, but the patient continues to experience a residual condition directly attributable to that injury.

Use this code when documenting a patient presenting with a chronic issue, such as persistent renal dysfunction, scarring, or other structural changes, that is a direct consequence of a previously sustained, but not specified, kidney injury. This applies when the acute phase of the original injury has passed, and the current encounter addresses the lasting impact.

• Always sequence this "S" (sequela) code second, after the code describing the specific sequela (e.g., chronic kidney disease).
• Ensure documentation clearly links the current condition to a prior kidney injury, even if the exact nature of the original injury is unknown.
• Avoid using this code for acute or current kidney injuries; those require an active injury code.
