About 66700: Ciliary body destruction by diathermy
Ophthalmologists report this procedure when using diathermy to destroy ciliary body tissue, typically as a cyclodestructive treatment for glaucoma.
An ophthalmologist uses diathermy to destroy targeted ciliary body tissue, reducing aqueous humor production. This cyclodestructive procedure may be used for glaucoma that remains difficult to control, including when other pressure-lowering approaches have not achieved the clinical goal. It is generally performed in an operating room or other surgical setting, rather than as a routine office procedure.
Select this code when the operative method is diathermy; other ciliary body destruction methods have separate codes. The operative report should identify the treated eye, indication, and technique performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
