Laryngeal surgery
About 31580: Laryngeal web reconstruction
Surgical correction of a laryngeal web that narrows the airway or affects voice, reported when the surgeon releases and reconstructs the webbed area.
An otolaryngologist performs this operation to correct a web of tissue joining parts of the larynx, commonly at the glottis. The web may cause a weak or hoarse voice, noisy breathing, or airway narrowing. The surgeon releases the tissue and reconstructs the laryngeal opening; the operative approach depends on the web’s extent and the patient’s anatomy. The procedure is generally performed in an operating room under anesthesia, rather than as an office laryngoscopy.
Report 31580 for the operative correction of the laryngeal web, not for diagnostic examination alone or removal of an unrelated vocal-cord lesion. The operative report should identify the web, its location and extent, the corrective work, and any reconstruction performed. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard reduction. Modifier 50 is inappropriate. Assistant-at-surgery and co-surgeon payment require supporting documentation; team surgery is not permitted.

31580 billing questions
How is 31580 different from laryngoplasty for laryngeal stenosis?
Use 31580 when the operative target is a laryngeal web. Laryngoplasty codes for stenosis address a stenotic condition rather than a web.
Can diagnostic laryngoscopy be reported with 31580?
The operative report should support the web correction, not just an examination. Whether a separately reported service is distinct depends on the work documented and applicable coding edits.
Should modifier 50 be used?
No. CMS identifies bilateral adjustment as inappropriate for this code.
What does the 90-day global period include?
It includes the day-before preoperative visit and 90 days of related postoperative care.
When can an assistant or co-surgeon be reported?
Assistant-at-surgery payment and co-surgeon payment require documentation supporting medical necessity or the co-surgeon role, respectively. Team surgery is not permitted.
Where these rates come from
