Major contusion of unspecified kidney, subsequent encounter

This code signifies a significant bruise to an unspecified kidney, indicating a more severe injury than a minor contusion. It suggests damage to the kidney tissue without a laceration or rupture. The "subsequent encounter" designation means the patient is receiving follow-up care for an injury that occurred previously.

Use this code for patients presenting for ongoing management, monitoring, or treatment of a major kidney contusion after the initial acute phase of injury. This includes follow-up appointments, imaging studies to assess healing, or management of complications arising from the contusion.

• Ensure documentation clearly specifies "major contusion" and not a minor one, and that the kidney is unspecified.
• Verify that the encounter is for follow-up care, not the initial treatment of the injury.
• Pair with an external cause code to fully describe the circumstances of the injury.
