About 61323: Cranial decompression with lobectomy
Reports cranial decompression that includes removal of a portion of brain tissue, typically during surgery for severe intracranial swelling or pressure.
A neurosurgeon performs a craniectomy or craniotomy to relieve pressure within the skull and removes a portion of brain tissue as part of that decompressive operation. The procedure is generally performed in an operating room for a patient with severe intracranial swelling or pressure requiring surgical decompression. The documented operative work must include the lobectomy component, not decompression alone.
Report this code when the operation includes both cranial decompression and lobectomy; code 61322 describes the related decompression service without lobectomy. The operative report should identify the decompressive approach, the tissue removed, and the reason for the operation. CMS 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 other procedures are subject to the standard 50% reduction. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
