Minor contusion of unspecified kidney, initial encounter

This code signifies a mild bruising of the kidney, without specifying which kidney, that occurred during the initial presentation for treatment. It indicates a superficial injury to the renal parenchyma, typically resulting from blunt force trauma, without significant disruption or hemorrhage.

Use this code for patients presenting with a suspected or confirmed minor kidney contusion following an injury, where the specific kidney (left or right) is not documented. This is appropriate for the initial encounter where the injury is first evaluated and treated.

• Ensure documentation explicitly states "minor contusion" and does not specify the affected kidney.
• Confirm this is the patient's first time receiving active treatment for this specific injury.
• If the specific kidney is known, a more precise code (e.g., S37.011A for right, S37.012A for left) should be used instead.
