Otolaryngology surgery
About 31370: Partial surgical removal of larynx
Reports an operation removing part of the larynx, typically for a laryngeal tumor, while retaining laryngeal tissue rather than removing the entire organ.
An otolaryngologist or head and neck surgeon reports this code when an operation removes part of the larynx, commonly to treat a laryngeal tumor, while leaving some laryngeal tissue in place. The service is typically performed in a hospital operating room. It represents a partial organ resection, not simply removal of a vocal-cord lesion or other limited tissue excision. The operative report should establish the extent of the resection and distinguish it from a total laryngectomy or a more specifically described partial procedure.
Report the code supported by the documented operation and its extent; the operative note should identify the tissue removed and any associated procedures. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care during that 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% reduction. Modifier 50 is inappropriate for this service. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

31370 billing questions
How is this different from code 31300?
Code 31370 represents removal of part of the larynx. Code 31300 is for a more limited laryngeal lesion or foreign-body procedure, not a partial organ resection.
When should a total laryngectomy code be considered instead?
Use a total laryngectomy code when the operation removes the entire larynx. This code describes an operation that leaves part of the larynx in place.
Should modifier 50 be appended for bilateral work?
No. Modifier 50 is inappropriate for this code; the service is not reported as a bilateral procedure.
What postoperative care is included in the global period?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, while team-surgery billing is not permitted.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures performed in the same session are subject to the standard multiple-procedure reduction.
