Contact with nail gun, initial encounter

This code signifies an injury resulting from direct contact with a nail gun. It specifically captures the initial presentation of a patient who has sustained trauma due to the operation or malfunction of this type of power tool. The injury can range from superficial wounds to deep penetrations, depending on the force and location of contact.

Apply this code when a patient presents for treatment of an injury directly caused by a nail gun, such as a nail penetrating the skin, a blunt force injury from the tool itself, or a ricochet incident involving the nail gun. This code is appropriate for the initial encounter for the specific injury sustained.

• Always code the specific injury (e.g., puncture wound, fracture) first, followed by this external cause code.
• Ensure proper sequencing, as external cause codes are supplementary.
• Verify the encounter type (initial, subsequent, sequela) for the correct 7th character.
