Laryngeal surgery
About 31591: Unilateral vocal fold medialization surgery
Reports framework surgery that moves one vocal fold toward the midline, commonly to improve glottic closure in unilateral vocal fold paralysis.
An otolaryngologist or laryngologist performs this framework procedure to move one vocal fold toward the midline and improve glottic closure. A typical indication is unilateral vocal fold paralysis or immobility causing a persistent voice or airway-protection problem. In a type I thyroplasty approach, the surgeon works through the neck and adjusts the thyroid cartilage framework, commonly placing an implant to medialize the fold. The procedure is generally performed in an operating room.
Report the code for unilateral medialization surgery, not for endoscopic injection augmentation or diagnostic examination alone. The operative report should identify the treated side, the indication, and the framework work performed. CMS assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery and co-surgeon payment require the documentation described in CMS rules; team surgery is not permitted.

31591 billing questions
How does this differ from vocal fold injection augmentation?
This code describes framework surgery that medializes one vocal fold. Code 31574 is for endoscopic injection augmentation, a different method of addressing glottic insufficiency.
What documentation supports reporting this code?
Document the indication, the side treated, and the operative steps showing framework medialization. The record should distinguish the surgery from injection augmentation or a diagnostic laryngeal examination.
Can the procedure be reported bilaterally?
CMS lists bilateral payment with modifier 50 at 150%. The operative documentation should support treatment of both sides.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
When is an assistant or co-surgeon paid?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
How are other procedures in the same session paid?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
