Puncture wound with foreign body of lip, sequela

This code signifies a long-term complication or late effect resulting from a puncture wound to the lip that involved a foreign object. It indicates that the patient is experiencing ongoing issues directly attributable to the original injury and the retained foreign body.

Apply this code when documentation clearly indicates a current condition or symptom (e.g., chronic pain, infection, scarring, nerve damage) that is a direct consequence of a previously sustained puncture wound to the lip with a foreign body. The "S" seventh character designates a sequela, meaning the initial injury has healed, but its effects persist.

• Always sequence this code after the code describing the specific sequela (e.g., chronic pain, scar formation).
• Ensure documentation explicitly links the current condition to the prior puncture wound with a foreign body.
• Do not use this code for initial encounters or active treatment of the acute injury; those require codes from the acute injury chapter.
