What 31365 covers
This operation removes the entire larynx and includes a radical neck dissection to remove cervical lymphatic tissue. Head and neck surgeons, commonly otolaryngologists, perform it in a hospital or other surgical facility, often for advanced laryngeal cancer. A permanent neck stoma provides the airway after the larynx is removed.
Report 31365 when the operative record supports both complete laryngeal removal and radical neck dissection in the same operation; total laryngectomy without that dissection is a different service. 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 others at 50%. Do not append modifier 50 for a bilateral adjustment. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

31365 billing questions

31365 includes total laryngectomy with radical neck dissection. Use 31360 for total laryngectomy without radical neck dissection.
Can the neck dissection be billed separately?
The radical neck dissection is included in 31365. Do not separately report another code for that same dissection.

An assistant at surgery may be paid. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.
What documentation supports 31365?
The operative report should establish complete removal of the larynx and performance of a radical neck dissection in the same session.
