What 62121 covers

A neurosurgeon repairs a skull-base defect associated with an encephalocele, in which intracranial tissue or its coverings protrude through the skull. The operation uses an open skull approach to address the defect and may include reconstruction needed to complete the repair. These cases are typically performed in a hospital operating room, often with neurosurgery and other surgical specialists involved when the anatomy requires it.

Report 62121 for the documented skull-base encephalocele repair, rather than a general repair of a cerebrospinal fluid leak or reconstruction of a separate skull defect. The operative note should identify the encephalocele, the skull-base defect, and the repair performed. This major surgery has a 90-day global period that includes the day-before preoperative visit and 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 for this service. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
