Unsp open wound of left middle finger w damage to nail, init

This code signifies an open wound on the left middle finger where the specific nature of the wound (e.g., laceration, puncture) is not documented. Crucially, it indicates that the nail of the left middle finger has sustained damage as part of this injury. This is an initial encounter for treatment of this specific injury.

Use this code when a patient presents with an open injury to their left middle finger, and the medical record clearly states damage to the nail, but the precise type of open wound is not specified. This code is appropriate for the first time the patient is seen for this particular injury.

• Ensure documentation explicitly states "unspecified open wound" or lacks further detail regarding the wound type.
• Verify the injury location is specifically the left middle finger and includes nail damage.
• Confirm this is the initial encounter for this injury; subsequent encounters will require a different seventh character.
