Otolaryngology surgery
About 31552: Laryngeal stenosis reconstruction with graft
Reports reconstructive laryngoplasty using a graft to enlarge a stenotic larynx in a patient age 12 or older.
An otolaryngologist performs this operation to reconstruct and widen a narrowed laryngeal airway using a graft. It is selected for laryngeal stenosis when reconstruction with graft material is performed, rather than an endoscopic dilation alone. The procedure is typically done in an operating room for a patient age 12 or older; the operative report should identify the stenosis and describe the graft-based reconstruction.
This is a major surgery with a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documented medical necessity, and co-surgeon payment requires supporting documentation; team surgery is not permitted.

31552 billing questions
How does this differ from 31551?
Both address laryngeal stenosis in patients age 12 or older. Report 31552 when the reconstruction uses a graft; 31551 is the corresponding option without a graft.
When would 31528 be considered instead?
31528 describes laryngoscopy with dilation. It is the endoscopic dilation approach, rather than graft-based reconstructive laryngoplasty.
Can modifier 50 be used for bilateral stenosis?
No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 is not used.
What documentation supports reporting 31552?
The operative report should establish laryngeal stenosis, the patient's age, and that graft material was used in the laryngeal reconstruction.
How are assistant and co-surgeon services handled?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
