What 61330 covers
This procedure relieves pressure within the orbit by removing bone through a cranial approach, creating more space for the orbital contents. It may be performed for severe proptosis or optic nerve compression, including in patients with thyroid-associated orbitopathy. Neurosurgeons and oculoplastic surgeons may perform it in a hospital operating room. The operative report should establish that the route was transcranial and that the work was orbital decompression rather than treatment of an intracranial lesion.
Report the code for the transcranial orbital decompression itself, with documentation of the indication, side, approach, and operative work. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. For bilateral surgery, modifier 50 is paid at 150%. 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 available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

- 61322Cranial decompression
- This code targets the orbit. Code 61322 describes cranial decompression without lobectomy, not orbital decompression.

61330 billing questions
How does this differ from orbital decompression through a lateral orbitotomy?
This code identifies decompression performed through a transcranial route. A lateral orbitotomy code, such as 67414, describes a different surgical approach.
What documentation supports reporting this code?
The operative report should identify the transcranial approach, the orbit decompressed, laterality, the reason for decompression, and the work performed.
How should bilateral decompression be reported?
Report bilateral surgery with modifier 50; CMS pays the bilateral procedure at 150%.
Does the code include postoperative care?
Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation, while team surgery is not permitted.
