About 31587: Cricoid split for airway enlargement
Reports surgical division of the cricoid framework to widen a narrowed airway, commonly for subglottic stenosis, rather than endoscopic lesion treatment.
A cricoid split divides the cricoid framework to increase airway caliber, most often to address fixed subglottic narrowing. An otolaryngologist or airway surgeon performs the operation in a surgical setting, commonly for a child with subglottic stenosis. The operative report should establish that the cricoid itself was split, rather than documenting only airway inspection or treatment of a vocal-fold lesion.
Report 31587 when the cricoid split is the laryngoplasty performed; the diagnosis of stenosis alone does not determine code selection. Document the indication, structures altered, and operative work so the procedure can be distinguished from other stenosis repairs. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. For procedures performed in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires medical-necessity documentation, co-surgeon payment requires supporting documentation, and team surgery is not permitted.

31587 compared with similar codes
Office rates for Minnesota, from the same CMS release.
Both concern laryngeal airway surgery, but 31587 is specific to splitting the cricoid; select 31554 only when its described stenosis reconstruction was performed.
31592 describes cricotracheal resection, a different operation for airway stenosis. It is not interchangeable with a cricoid split.

31587 billing questions
How is 31587 distinguished from the laryngoplasty codes for laryngeal stenosis?
Use 31587 when the documented operation is a cricoid split. Select a stenosis laryngoplasty code when the procedure performed matches that code’s specific reconstructive service.
Does a diagnosis of subglottic stenosis support 31587 by itself?
No. The operative report should describe the cricoid split and the airway structures treated; the diagnosis alone does not establish that this procedure was performed.
Should modifier 50 be appended for a bilateral case?
No. CMS identifies bilateral adjustment as inappropriate for this code.
What postoperative care is included in the global period?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are other procedures in the same operative session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.
When can an assistant or co-surgeon be paid?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
