Otolaryngology
About 31529: Subsequent laryngeal dilation
Direct laryngoscopy with dilation treats persistent or recurrent laryngeal narrowing during a subsequent procedure in a dilation series.
An otolaryngologist uses direct laryngoscopy to examine the larynx and dilate a narrowed area, commonly for persistent or recurrent stenosis after an earlier dilation. The service is typically performed in an operating room, often under general anesthesia. This code identifies a subsequent dilation procedure in the treatment series, rather than the initial dilation represented by its sibling code.
Report the subsequent-service code when the operative record supports that the patient is returning for another dilation procedure; document the laryngeal finding, dilation performed, and relevant prior treatment. The procedure has a 0-day global period, so same-day preoperative and postoperative care are included. When related endoscopies are performed together, CMS endoscopy-family pricing applies. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

31529 billing questions
How does this code differ from 31528?
31529 is for a subsequent laryngeal dilation procedure in a treatment series. Use 31528 for the initial dilation.
Does a second dilation during the same operation make this the subsequent code?
No. The distinction is between the initial and a subsequent procedure in the treatment series, not the number of dilation maneuvers during one operation.
Can diagnostic laryngoscopy be separately reported with the dilation?
The laryngoscopic visualization used to perform the dilation is part of the service. Do not separately report a diagnostic laryngoscopy for that same operative inspection.
Should modifier 50 be appended for dilation on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code.
What documentation supports reporting a subsequent dilation?
Document the laryngeal narrowing, the direct laryngoscopy and dilation performed, and the prior treatment supporting that this is a subsequent procedure in the series.
When may an assistant-at-surgery be paid?
Only when the record documents medical necessity for the assistant. CMS does not permit co-surgeon or team-surgery payment for this code.
