Ophthalmic surgery
About 66830: Surgical removal of a lens lesion
Report this service when an ophthalmic surgeon surgically removes a discrete lesion, such as a cyst or tumor, involving the eye’s natural lens.
An ophthalmic surgeon uses this code for surgical removal of a discrete lesion involving the natural lens, such as a lens cyst or tumor. The operative target is the lesion itself, rather than a secondary cataract membrane or lens material removed as part of cataract surgery. The procedure is typically performed in a surgical setting, with the surgeon documenting the lesion and the removal performed.
Select the code based on the operative report’s description of a lens lesion and its removal. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For bilateral surgery reported with modifier 50, CMS pays 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.
