Nail entering through skin, initial encounter

This code describes an injury where a nail (fastener) has penetrated the skin. This typically involves a foreign body embedded in the tissue, often resulting from an accidental puncture wound.

Assign this code when documenting the initial treatment for a patient presenting with a nail embedded in their skin. This includes emergency department visits, urgent care encounters, or initial physician office visits for removal and wound care.

• Ensure the documentation clearly specifies a "nail" (e.g., construction nail, finishing nail) as the foreign body, not a fingernail or toenail.
• The "A" in the seventh character indicates an initial encounter for this injury, meaning the patient is receiving active treatment.
• Consider additional codes for associated injuries, such as open wound, infection, or nerve damage, if documented.
