What 66680 covers
This service restores disrupted iris or ciliary-body anatomy, including an iris root pulled away from its attachment or a cyclodialysis cleft. Ophthalmologists typically perform the repair under an operating microscope in an operating room or ambulatory surgery center, often after ocular trauma. It addresses structural injury rather than removal of an iris lesion or placement of an artificial iris.
Choose the code based on the repair actually performed, and document the affected structure, operative findings, repair, and laterality. It has a 90-day global period that includes the day-before preoperative visit and 90 days of related postoperative care. When performed bilaterally and reported with modifier 50, payment is 150%. For multiple procedures in the same session, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment is restricted; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

66680 billing questions
When is this code appropriate instead of an iris-lesion removal code?
Use this code for repair of disrupted iris or ciliary-body anatomy. Iris-lesion removal codes describe excision of a lesion, not repair of an injury.
How should this code be distinguished from 66682?
Both codes concern iris or ciliary-body repair. Base the choice on the specific operative work documented and the applicable code descriptor, not on the diagnosis alone.
Is postoperative care separately reported during the global period?
Related postoperative care for 90 days is included, as is the preoperative visit on the day before surgery.
How is bilateral repair reported?
For bilateral procedures, report modifier 50; CMS pays the bilateral procedure at 150%.
How does payment change when other procedures are performed in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures at 50%. Assistant-at-surgery payment is restricted; co-surgeon payment requires supporting documentation.
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.
