Pnctr w/o foreign body of unsp finger w damage to nail, init

This code signifies a penetrating injury to an unspecified finger, characterized by a sharp object piercing the skin without leaving any foreign material behind. Crucially, the injury also involves damage to the fingernail or nail bed. This is the initial encounter for this specific injury.

Apply this code when a patient presents for the first time with a puncture wound to any finger where the specific digit is not documented, and the injury has affected the nail structure. This would include scenarios like a needle stick or a thorn puncture that has also caused a crack, avulsion, or other damage to the nail.

• Ensure documentation explicitly states "puncture wound" and "without foreign body."
• Verify that the medical record confirms damage to the nail (e.g., nail avulsion, laceration of nail bed).
• Only use this code for the initial treatment of the injury; subsequent encounters will require a different seventh character.
