What 62162 covers
A neurosurgeon uses an endoscope through a small cranial opening to reach and remove an intracranial colloid cyst. A common clinical setting is a third-ventricle cyst near the foramen of Monro, particularly when it obstructs cerebrospinal fluid flow. The procedure is generally performed in a hospital operating room; the operative report should identify the cyst and document endoscopic excision rather than cyst fenestration or removal of another type of tumor.
Report this code for endoscopic excision of the colloid cyst, supported by the operative approach and the lesion treated. It has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is not appropriate for this midline procedure.

62162 billing questions
How is this different from 62161?
62162 describes endoscopic excision of a colloid cyst. Use 62161 when the endoscopic procedure is cyst fenestration rather than colloid cyst excision.
What should the operative report document?
Document the intracranial colloid cyst, the endoscopic approach, and the excision performed. The report should distinguish excision from fenestration and identify the treated lesion.
Does the 90-day global period include postoperative visits?
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?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, with other procedures subject to the standard multiple-procedure reduction.
Should modifier 50 be appended?
No. This midline intracranial procedure is not appropriate for bilateral reporting with modifier 50.
