Puncture wound with foreign body of vocal cord, sequela

This code signifies a long-term complication or late effect resulting from a previous puncture wound to the vocal cord, where a foreign body was present. It indicates that the patient is experiencing ongoing issues directly attributable to that past injury and retained foreign material.

Apply this code when documentation clearly indicates a current condition or symptom is a residual effect of a prior puncture wound to the vocal cord involving a foreign body. This is used for conditions presenting after the acute phase of the original injury has passed, such as chronic hoarseness, vocal cord dysfunction, or granuloma formation due to the retained foreign body.

• Always assign this sequela code after the 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 this code for the initial or acute treatment of the puncture wound itself; it is strictly for late effects.
