Unsp open wound of left ring finger w/o damage to nail, init

This code signifies an open injury to the left ring finger that has broken the skin, but the nail itself remains intact and undamaged. The specific nature of the wound (e.g., laceration, puncture) is not documented, and this is the initial treatment for the injury.

Apply this code when a patient presents with an open wound on their left ring finger, and the medical record explicitly states that the nail unit is not involved. This is appropriate for the first encounter for this specific injury when the wound type is not further specified.

• Ensure the documentation specifies "left ring finger" and "without damage to nail."
• Only use for the initial treatment of the injury; subsequent encounters will require a different seventh character.
• If the wound type (e.g., laceration, puncture) is documented, a more specific code should be used.
