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

This code signifies a bruise to the left index finger that also involves injury to the fingernail or nail bed. The damage to the nail could range from a subungual hematoma (blood under the nail) to a laceration or avulsion of the nail plate.

Apply this code when documenting the initial presentation and treatment of a patient who has sustained a blunt force injury to their left index finger, resulting in both a contusion and observable damage to the nail structure. This is appropriate for acute injuries seen in an emergency department or initial office visit.

• Ensure documentation clearly specifies the left index finger and involvement of the nail.
• Confirm this is the patient's first encounter for this specific injury; subsequent care would require a different encounter character.
• Look for associated codes for open wounds or fractures if present, as a contusion code alone may not fully capture the injury severity.
