What 66762 covers
An ophthalmologist uses laser photocoagulation to alter the contour of the iris, commonly with peripheral laser iridoplasty for persistent appositional angle closure or plateau iris after a patent iridotomy. The treatment targets iris configuration rather than creating an opening through the iris or treating the ciliary body. It is typically performed in an ophthalmology setting with a slit lamp and a contact lens used to focus the laser.
Report the procedure when the documented treatment reshapes iris tissue with photocoagulation; an iridotomy that creates an opening is a different service. The record should identify the clinical reason, treated eye, and laser treatment performed. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. For bilateral treatment, modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted, and co-surgeon and team-surgery billing are not permitted.

- 65820 is goniotomy, which treats the trabecular outflow pathway. It is not an iris photocoagulation procedure.
66762 billing questions
How is this different from laser iridotomy?
Iridoplasty reshapes the iris with photocoagulation. Iridotomy creates an opening through the iris, often to relieve pupillary block.
What documentation supports reporting this procedure?
Document the indication for reshaping, the eye treated, and the laser treatment performed. The record should distinguish iris contour treatment from creation of an iris opening.
How should bilateral treatment be reported?
When both eyes are treated, report modifier 50; CMS pays the bilateral procedure at 150%.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant surgeon or co-surgeon be billed?
CMS does not pay an assistant at surgery for this procedure. Co-surgeons and team surgery are not permitted.
