About 62165: Endoscopic transsphenoidal pituitary tumor excision

Endoscopic transnasal or transsphenoidal removal of a pituitary tumor is reported for operative resection through the nasal corridor.

This service covers endoscopic removal of a pituitary tumor through a transnasal or transsphenoidal route. A neurosurgeon typically performs the tumor resection in a hospital operating room; an otolaryngologist may participate in establishing or closing the nasal corridor. The operative report should identify the pituitary lesion, endoscopic technique, and route used.

Report the code when the surgeon performs the endoscopic pituitary tumor excision, rather than a nonendoscopic or transcranial approach. The 90-day global period includes 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%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity, co-surgeon payment requires supporting documentation, and team surgery is not permitted.

62165 billing questions

How does this differ from code 61548?

Use 62165 for endoscopic pituitary tumor removal through the transnasal or transsphenoidal route. Code 61548 represents pituitary tumor excision through that route without the endoscopic service described by 62165.

When is code 61546 more appropriate?

Code 61546 is the alternative when the surgeon removes the pituitary tumor through a transcranial approach. Code 62165 describes endoscopic removal through the nasal or transsphenoidal route.

Can modifier 50 be reported for bilateral work?

No. Modifier 50 is inappropriate for this code because the descriptor or anatomy does not support a bilateral adjustment.

How are other procedures paid when performed in the same session?

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

What documentation supports an assistant or co-surgeon claim?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
