Puncture wound with foreign body of left wrist, sequela

This code describes a puncture injury to the left wrist where a foreign object remains embedded, and the current encounter addresses a long-term complication or residual effect of that initial injury. This indicates that the initial acute injury has passed, and the patient is now presenting for issues directly stemming from the retained foreign body.

Apply this code when a patient presents with a chronic issue, such as infection, pain, nerve damage, or restricted movement, that is directly attributable to a foreign body that was previously, and still is, lodged in their left wrist from a puncture wound. This is appropriate for follow-up care related to the sequelae, not the initial acute injury or removal of the foreign body itself.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, infection).
• Ensure documentation clearly states the presence of a retained foreign body and that the current visit addresses a long-term complication.
• Do not use for initial injury encounters or for acute complications immediately following the injury; those would use the acute injury codes.
