What 31390 covers
This code describes an operation removing the larynx and pharynx, generally performed by an otolaryngologist or head and neck surgeon for disease involving both structures, such as an extensive malignancy. The procedure is typically done in a hospital operating room and may be followed by reconstruction to restore continuity or support swallowing. The operative report should identify the structures removed and the extent of the resection.
Report the code when the documented operation includes removal of both the larynx and pharynx; a larynx-only resection or removal of a limited laryngeal lesion is different. The service has a 90-day global period, including 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% multiple-procedure reduction. Do not use modifier 50. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

31390 billing questions
How is this distinguished from a total laryngectomy?
Use this code when the operation removes both the larynx and pharynx. A total laryngectomy without pharyngeal removal is represented by a different code.
Can modifier 50 be used for bilateral work?
No. The CMS bilateral adjustment does not apply to this code; the descriptor or anatomy makes modifier 50 inappropriate.
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 in that session are subject to the standard multiple-procedure reduction.
May an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
What documentation supports this code?
The operative report should establish that both the larynx and pharynx were removed and describe the resection performed.
