Laryngeal surgery
About 31400: Operative larynx revision
Reports an operative revision of laryngeal anatomy, typically by an otolaryngologist when prior laryngeal surgery requires surgical correction.
CPT 31400 represents an operative revision of laryngeal anatomy, commonly performed by an otolaryngologist or head and neck surgeon in an operating room. It is used when the surgeon revises a prior laryngeal alteration rather than performing only an examination, biopsy, or routine endoscopic treatment. The operative report should identify the laryngeal structures revised, the corrective work performed, and the reason for revision.
Select this code when the documented operation fits a general larynx revision and a more specific laryngoplasty or other laryngeal procedure does not better describe the work. The 90-day global period includes the day-before preoperative visit and 90 days of 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 50% reduction. Report one service rather than modifier 50. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

31400 billing questions
When should I report 31400 instead of a laryngoplasty code?
Use 31400 for a documented operative revision that is not more specifically described by a laryngoplasty code. If the operative report identifies a specific reconstructive technique, evaluate the corresponding specific code.
Can I report 31400 for a laryngeal examination or biopsy?
No. The operative documentation must support revision of laryngeal anatomy; examination or biopsy alone does not describe this service.
What postoperative care is included?
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 session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple procedure reduction.
Can I report modifier 50 for bilateral laryngeal revision?
No. Report the laryngeal revision as one service; modifier 50 is not appropriate for this code.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons and team surgery are not permitted for this code.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
