Other injury of left kidney, sequela

This code signifies a long-term or late-developing complication resulting from a previous, unspecified injury to the left kidney. It indicates that the initial traumatic event has resolved, but its lasting effects on the left kidney are still present and require ongoing management. These sequelae could include chronic pain, functional impairment, or structural changes.

Use this code when documenting conditions such as chronic hydronephrosis, renal scarring, or persistent hematuria that are directly attributable to a past, non-specific injury of the left kidney. This code is appropriate when the acute phase of the original injury has passed, and the patient is being treated for the residual effects.

• Always ensure documentation clearly links the current condition to a previous left kidney injury.
• This code requires a seventh character "S" to indicate sequela, meaning the patient is seen for the residual effects of a past injury.
• Do not use this code for acute injuries; instead, use the appropriate acute injury code from the S37.09x category.
