What 66150 covers
An ophthalmologist performs this filtration operation by using a trephine to create a small opening through the sclera and removing a portion of peripheral iris. The opening provides a route for aqueous humor to leave the anterior chamber and collect beneath the conjunctiva. The code is specific to this trephination technique, rather than glaucoma surgery generally, and is selected from the operative work documented by the surgeon.
The operative report should identify the trephination and iris removal, the treated eye, and any other procedures performed in the same session. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons require supporting documentation, and team surgery is 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.

66150 billing questions
How is 66150 distinguished from trabeculectomy?
Use 66150 when the documented filtration operation uses scleral trephination with peripheral iris removal. A trabeculectomy is reported with the code matching its technique and prior-surgery circumstances.
What operative details support 66150?
The report should identify the trephine-created scleral opening and peripheral iridectomy, along with the treated eye and any other procedures performed.
How is bilateral surgery reported under the CMS fee schedule?
Bilateral reporting with modifier 50 is paid at 150% under the CMS rule for this code.
Are assistant surgeons or co-surgeons payable?
Assistant-at-surgery payment is restricted. Co-surgeons are payable only with supporting documentation; team surgery is not permitted.
What care is included in the global period?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
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.
