Laceration with foreign body of larynx, subsequent encounter

This diagnosis code indicates a cut or tear in the larynx that includes a foreign object embedded within the tissue, specifically for a patient presenting for follow-up care after initial treatment. This injury often results from trauma where an external object penetrates the laryngeal structures.

Apply this code for subsequent encounters when a patient returns for wound care, monitoring of healing, or removal of the foreign body following the initial treatment of a laryngeal laceration with an embedded foreign object. Documentation should clearly state the presence of a foreign body and that the visit is not for the initial active treatment of the injury.

• Ensure documentation specifies "subsequent encounter" and the continued presence of a foreign body.
• Distinguish from initial encounter codes (ending in A) and sequela codes (ending in S).
• Code the specific type of foreign body if known and documented, using an additional external cause code.
