What 31380 covers
An otolaryngologist or head-and-neck surgeon performs this operation in a surgical facility to remove part of the larynx, commonly for a laryngeal malignancy or another lesion requiring resection. The surgeon removes the involved portion while retaining laryngeal tissue; the exact anatomy and extent of resection must support this specific partial-laryngectomy code. A limited lesion excision and removal of the entire larynx represent different services.
Choose the code that matches the operative technique and extent documented in the operative report, rather than relying on the diagnosis alone. The report should identify the laryngeal structures removed and any associated procedures. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral adjustment is inappropriate. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is not permitted.

31380 billing questions
How do I distinguish this code from another partial-laryngectomy code?
Match the code to the specific partial-resection technique and extent documented in the operative report. Do not select among partial-laryngectomy codes from the diagnosis alone.
Is this code appropriate for a limited laryngeal lesion excision?
Use this code when the documented service is a partial laryngectomy, not simply because a laryngeal lesion was removed. A more limited lesion-removal service may be represented by 31300.
Does the 90-day global period include related postoperative care?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
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%. Bilateral adjustment is inappropriate for this code.
