Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
