What 66630 covers
An ophthalmologist removes a portion of iris through a corneoscleral incision for a documented indication other than glaucoma. The operation is performed in an operating room. The operative report should identify the non-glaucoma reason for surgery, the eye treated, the approach, and the iris tissue removed. A lesion-directed procedure is distinguished by its specific lesion-removal purpose.
Report 66630 when the procedure and indication match this non-glaucoma iridectomy, rather than a glaucoma-directed or lesion-removal code. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and 90 days of related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. CMS does not pay an assistant at surgery and does not permit co-surgeons or team surgery for this code.
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.

66630 billing questions
How is 66630 distinguished from 66625?
Use 66630 when the iridectomy is for a documented indication other than glaucoma. Code 66625 is the glaucoma-directed iridectomy in this family.
When is 66600 a better choice?
Use 66600 when the procedure is specifically for removal of an iris lesion. Code 66630 describes an iridectomy for a non-glaucoma indication other than lesion removal.
What documentation supports 66630?
The operative report should state the non-glaucoma indication, identify the eye and surgical approach, and describe the iris tissue removed.
How are bilateral procedures reported?
CMS identifies this as a bilateral procedure; reporting modifier 50 is paid at 150%.
Are the preoperative visit and postoperative care separately included?
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.
