Contusion of unsp little finger w damage to nail, init

This code signifies a bruise to the little finger where the nail or nail bed has also sustained injury. This damage could include subungual hematoma, nail avulsion, or other trauma directly affecting the nail structure, resulting from blunt force.

Apply this code when documentation specifies a contusion of the little finger, and explicitly mentions associated damage to the nail (e.g., "crushed nail," "subungual hematoma," "nail plate injury"). This is appropriate for the initial treatment of such an injury.

• Ensure the documentation clearly specifies the little finger and involvement of the nail.
• Verify that this is the patient's first encounter for this specific injury.
• Do not use if the injury is an open wound, fracture, or dislocation; those require more specific codes.
