Unspecified injury of unspecified kidney, sequela

This code indicates a long-term complication or residual effect stemming from an unspecified injury to an unspecified kidney. It signifies that the acute phase of the kidney injury has passed, and the patient is now experiencing a chronic or late-developing consequence. The specific nature of the original injury and the affected kidney are not documented.

This code is appropriate when documenting a patient's follow-up care for a persistent issue related to a past, vaguely defined kidney trauma. It should be used when the medical record lacks specific details about the initial injury type (e.g., contusion, laceration) or which kidney was affected, and the encounter is for managing a sequela.

• Always strive for more specific codes if the type of kidney injury and laterality are known.
• This code is for sequela encounters only, indicated by the "S" seventh character.
• Ensure documentation clearly supports that the current condition is a residual effect of a past injury.
