What 31368 covers

An otolaryngologist or head and neck surgeon reports this service when removing part of the larynx and performing radical neck dissections on both sides during the same operation. It is most often associated with treatment of laryngeal cancer when the operative plan includes both laryngeal resection and bilateral neck surgery. The code distinguishes this combined extent of surgery from partial laryngeal procedures without neck dissection or with dissection on only one side.

The operative report should identify the partial laryngeal resection and document the radical neck dissection on each side. The day-before preoperative visit and 90 days of related postoperative care are included in the 90-day global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

31368 billing questions

How does this differ from 31367?

31368 represents partial laryngeal surgery with radical neck dissections on both sides. 31367 is the counterpart with a unilateral radical neck dissection.

Should modifier 50 be appended for the two-sided neck surgery?

No. The bilateral neck dissection is part of this code’s described operative scope, and the CMS bilateral adjustment does not apply.

What documentation supports reporting this code?

The operative report should describe the partial laryngeal resection and the radical neck dissection performed on each side. The documented operative extent should support the bilateral code rather than a unilateral or no-dissection variant.

How are other procedures in the same session paid?

Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50% when performed in the same session.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
