External constriction of part of throat, sequela

This code signifies a lasting consequence or late effect resulting from an external constriction that affected a portion of the throat. This could stem from various past injuries or events, leading to chronic symptoms or anatomical changes in the pharyngeal or laryngeal region. The "sequela" indicates that the initial injury has healed, but its residual effects persist.

Apply this code when documentation clearly indicates a current condition in the throat that is a direct, long-term result of a previously sustained external constrictive injury. This is appropriate for chronic issues like strictures, dysphagia, or respiratory compromise directly attributable to the past constriction. Documentation should specify the external nature of the original constriction and the causal link to the current throat issue.

• Always sequence the sequela code first, followed by codes for the specific manifestation(s) of the sequela (e.g., dysphagia, stricture).
• Ensure the "S" seventh character is used for sequela, indicating a late effect.
• Distinguish from acute external constriction injuries (S10.14XA, S10.14XD) which describe the initial injury, not its long-term effects.
