Pnctr w fb of pharynx and cervical esophagus, sequela

This code describes a puncture wound to the pharynx or cervical esophagus that includes a retained foreign body, with the encounter being for the sequelae or late effects of the initial injury. This indicates that the acute phase of the injury has passed, and the patient is presenting for complications or long-term issues resulting from the original wound and retained object.

Use this code when a patient presents with ongoing symptoms or complications (e.g., chronic pain, infection, stricture, fistula formation) directly attributable to a past puncture wound of the pharynx or cervical esophagus where a foreign body was present. Documentation should clearly state the nature of the sequela and link it to the previous injury with a retained foreign body.

• Always sequence the sequela code first, followed by any codes for the specific complication(s) being treated.
• Ensure documentation specifies "sequela" or "late effect" and clearly identifies the foreign body and puncture wound location.
• Distinguish from acute injury codes (S11.24XA/D) which are used for initial or subsequent encounters for active treatment of the wound itself.
