Puncture wound without foreign body of larynx, init encntr

This code signifies a penetrating injury to the larynx caused by a sharp object, where no foreign material remains embedded in the tissue. It specifically refers to the initial treatment or evaluation of such an injury.

Apply this code for patients presenting with a fresh puncture wound to the voice box, such as from a needle or a small, sharp instrument, without evidence of retained foreign body. Documentation should clearly state "puncture wound," "larynx," and indicate that this is the first time the patient is being seen for this injury.

• Differentiate from open wounds with foreign body (S11.02xA) or lacerations (S11.00xA).
• Ensure documentation specifies "without foreign body" to avoid miscoding.
• Always append the appropriate seventh character for subsequent encounters (D) or sequela (S).
