What 66155 covers
An ophthalmologist performs this operation to create a filtration pathway through the sclera, allowing aqueous fluid to drain and helping reduce intraocular pressure. The procedure includes removal of a portion of the iris. It is used for glaucoma when surgical pressure reduction is needed; the operative report should establish that the surgeon performed the filtration procedure with an iridectomy. It is typically performed in an operating room or ambulatory surgery setting.
Report one unit for the operated eye when the documented procedure matches this service. CMS assigns a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. If other procedures are performed in the same session, CMS pays the highest-valued procedure in full and applies the standard reduction to the others. With modifier 50, the bilateral procedure is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

66155 billing questions
How does this differ from 66150?
This code includes an iridectomy as part of the glaucoma filtration surgery. Code 66150 describes the corresponding procedure without an iridectomy.
What documentation supports this code?
The operative report should document the scleral filtration procedure and the iridectomy. A diagnosis of glaucoma alone does not establish that this specific operation was performed.
Is related postoperative care separately reported?
The 90-day global period includes related postoperative care and the day-before preoperative visit. Unrelated services are distinct from that included care.
How is bilateral surgery reported?
For bilateral surgery, report modifier 50; CMS pays the bilateral procedure at 150%.
Can an assistant or co-surgeon be reported?
CMS restricts assistant-at-surgery payment for this procedure. Co-surgeons and team surgery are not permitted.
What happens when another procedure is performed in the same session?
CMS pays the highest-valued procedure in full and applies the standard multiple procedure reduction to the other procedures.
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.
