Minor contusion of unspecified kidney, sequela

This code signifies a long-term effect or complication resulting from a minor bruise to an unspecified kidney. It indicates that the initial injury has healed, but there are residual symptoms or conditions directly attributable to that past renal contusion.

Apply this code when documenting a patient presenting with ongoing issues, such as persistent microscopic hematuria, mild renal dysfunction, or scar tissue formation, that are directly linked to a previously sustained minor kidney contusion. This code is appropriate when the acute phase of the injury has passed, and the current encounter addresses these lasting effects.

• Always ensure documentation clearly links the current condition to a previous minor kidney contusion.
• This "S" seventh character indicates a sequela, meaning the patient is being seen for a complication or residual effect of a past injury.
• Do not use this code for the initial injury or for active treatment of the acute contusion.
