Contusion of unsp index finger w damage to nail, init encntr

This code signifies a bruise to an unidentifiable index finger, specifically involving trauma to the fingernail. This injury typically results from blunt force impact, causing bleeding under the nail (subungual hematoma) or damage to the nail plate itself.

Apply this code when documentation indicates a contusion of the index finger, and the specific left or right side is not specified, but there is clear involvement of the nail. This is appropriate for the initial visit for this injury, such as in an emergency department or initial clinic consultation.

• Ensure the documentation explicitly states "index finger" and "unspecified" for laterality.
• Confirm that damage to the nail (e.g., subungual hematoma, nail plate avulsion) is noted.
• This code is for the initial encounter; subsequent care will require a different encounter character.
