Major contusion of left kidney, initial encounter

This code signifies a significant bruise or blunt injury to the left kidney, indicating damage to the renal parenchyma without a complete tear or rupture. It implies a substantial impact that has caused bleeding and swelling within the kidney tissue.

Apply this code for patients presenting with a confirmed diagnosis of a severe contusion to the left kidney, often following trauma such as a fall, motor vehicle accident, or direct blow to the flank. This code is appropriate for the initial treatment phase of such an injury.

• Ensure documentation specifies "major" or "severe" contusion to differentiate from minor contusions.
• Confirm the laterality is explicitly documented as "left kidney."
• Verify this is the patient's initial encounter for this specific injury; subsequent encounters will require a different seventh character.
