Major contusion of left kidney, subsequent encounter

This code signifies a significant bruise or blunt injury to the left kidney that occurred previously and is now being treated or evaluated again. It indicates damage to the kidney tissue without a complete tear or rupture, but severe enough to be classified as "major."

This code is appropriate for follow-up visits, subsequent hospitalizations, or ongoing management of a patient who previously sustained a major contusion to their left kidney. This includes scenarios where the patient is returning for imaging, pain management, or monitoring of kidney function after the initial injury.

• Ensure documentation clearly specifies "major contusion" and the left kidney.
• Verify that the encounter is for follow-up care, not the initial injury, to justify the "D" seventh character.
• Look for associated injuries or complications that may require additional coding.
