What 62146 covers
A neurosurgeon uses the patient’s own bone to rebuild a skull defect measuring less than 5 cm in diameter. The graft may be used to restore cranial protection and contour after a prior craniectomy, traumatic injury, or removal of bone during treatment of an intracranial condition. This procedure is typically performed in an operating room in a hospital or other surgical facility.
Report this code when the documented repair includes an autograft and the defect meets the code’s size criterion; document the defect measurement and the use of the patient’s bone. The service has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. 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. Modifier 50 is inappropriate for this code. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

62146 billing questions
How is this code distinguished from 62140?
62146 describes reconstruction using the patient’s own bone for a defect under 5 cm. 62140 is the corresponding small-defect cranioplasty without an autograft.
When should 62147 be considered?
Use 62147 for cranioplasty with autograft when the defect is greater than 5 cm in diameter. Document the measured defect and the graft used.
What documentation supports 62146?
The operative report should establish the defect’s diameter, the reconstruction performed, and that the graft was the patient’s own bone.
Can an assistant surgeon be reported?
Assistant-at-surgery payment may be available for this procedure. Co-surgeon payment requires supporting documentation.
How does the global period affect postoperative care?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
Should modifier 50 be used for defects on both sides?
No. Modifier 50 is inappropriate for this code; the descriptor and anatomy do not support bilateral adjustment.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
