Contusion of unsp middle finger with damage to nail, sequela

This code signifies a bruise to the middle finger, specifically involving damage to the nail, that is a residual effect or complication of an initial injury. It indicates that the acute phase of the injury has passed, and the patient is presenting with a long-term consequence of the original contusion.

Use this code when documenting a patient presenting with a chronic issue, such as nail deformity, discoloration, or persistent pain, resulting from a past contusion to the middle finger. This code is appropriate for follow-up encounters addressing the sequelae of the original injury, not the initial acute event.

• Ensure documentation clearly states the injury is a "sequela" or a "late effect" of a previous contusion.
• Verify that the affected digit is specifically the middle finger and that nail damage is present.
• Do not use this code for the initial acute injury; instead, use an acute contusion code with an appropriate seventh character.
