Puncture wound with foreign body of larynx, sequela

This code describes a long-term complication or late effect resulting from a puncture wound to the larynx that involved a foreign body. It indicates that the initial injury has healed, but residual issues related to the foreign body or the wound itself are still present. This could include chronic inflammation, scarring, voice changes, or persistent discomfort.

Use this code when documentation clearly states a patient is experiencing sequelae (late effects) from a past puncture wound of the larynx that involved a foreign body. This applies when the acute phase of the injury has passed, and the current encounter addresses ongoing problems directly attributable to that historical event. Documentation should specify the nature of the sequela.

• Always sequence the sequela code first, followed by a code describing the specific nature of the sequela (e.g., chronic laryngitis, vocal cord paralysis).
• Ensure documentation explicitly links the current condition to the past puncture wound with a foreign body. Do not use for acute injuries.
• Distinguish from current foreign bodies in the larynx (T17.3xx) or acute puncture wounds without a foreign body (S11.01XA).
