Contusion of left middle finger w damage to nail, init

This diagnosis code signifies a bruise to the middle finger of the left hand, specifically indicating that the nail structure has also sustained injury. This damage could range from a subungual hematoma to a crushed nail bed, resulting from blunt force trauma.

Apply this code when documenting the initial treatment for a patient presenting with a contusion to their left middle finger where the fingernail is visibly affected. This includes injuries such as being struck by an object, catching the finger in a door, or other blunt trauma causing both soft tissue and nail damage.

• Ensure documentation clearly specifies the left middle finger and involvement of the nail.
• Confirm this is the initial encounter for the injury; subsequent visits will require a different seventh character.
• Look for associated injuries like fractures (e.g., phalanx) and code them separately if present.
