Major contusion of right kidney, initial encounter

This code signifies a significant bruise to the right kidney, indicating damage to the renal parenchyma without a complete tear or rupture. It typically results from blunt force trauma to the flank or back, leading to localized bleeding and swelling within the kidney.

Apply this code for patients presenting with a confirmed diagnosis of a substantial contusion to the right kidney, often identified through imaging studies like CT scans. This is appropriate for the initial assessment and treatment of the injury.

• Ensure documentation clearly specifies the right kidney and the nature of the injury as a contusion, not a laceration or rupture.
• Confirm this is the patient's first presentation for this specific injury to justify the "initial encounter" designation.
• Look for associated symptoms like hematuria, flank pain, or tenderness to support the diagnosis.
