Puncture wound with foreign body of left hand, sequela

This code signifies a puncture wound on the left hand where a foreign object remains embedded, and the encounter is for the management of a late effect or complication of that initial injury. This could include chronic pain, infection, nerve damage, or impaired function resulting from the retained foreign body.

Apply this code when a patient presents for treatment of a long-term consequence directly attributable to a puncture wound of the left hand that involved a foreign body. This is appropriate for follow-up visits addressing ongoing issues after the initial injury and acute treatment. Do not use for the initial injury or acute care.

• Ensure documentation clearly states the encounter is for a sequela of the original injury, not the initial acute event.
• Always code the specific sequela (e.g., chronic pain, infection) as the primary diagnosis, with this code as a secondary diagnosis.
• Verify the laterality (left hand) is accurately documented.
