Puncture wound without foreign body of larynx, subs encntr

This code signifies a penetrating injury to the larynx caused by a sharp object, where no foreign material remains embedded. It specifically indicates that the patient is presenting for follow-up care, such as wound checks, dressing changes, or evaluation of healing, after the initial treatment of the puncture wound.

This code is appropriate for subsequent encounters when a patient receives ongoing care for a puncture wound to the larynx that did not involve a retained foreign body. Documentation should clearly state "puncture wound of larynx," specify the absence of a foreign body, and indicate that this is not the initial treatment visit.

• Ensure documentation explicitly states "subsequent encounter" or similar language indicating ongoing care.
• Distinguish from initial encounters (S11.013A) and sequela (S11.013S).
• Verify the absence of a foreign body; if present, a different code would be required.
