What 66770 covers

CPT 66770 describes surgical removal of a lesion involving the ciliary body, the structure inside the eye that produces aqueous humor. An ophthalmologist typically performs the procedure in an operating room, using an approach suited to the lesion’s location and extent. It is distinct from procedures that destroy ciliary tissue to lower intraocular pressure; those treat glaucoma rather than excise a lesion.

Select the code when the operative record supports excision of a ciliary body lesion. Documentation should identify the lesion’s site and describe the excision performed and the treated eye. 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 is restricted; co-surgeons and team surgery are 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.

66770 billing questions

How is 66770 different from excision of an iris lesion?

66770 is for a lesion involving the ciliary body. Use the iris-lesion procedure when the excised lesion is confined to the iris.

Can 66770 be reported with a ciliary body destruction procedure?

They describe different treatment goals: 66770 removes a lesion, while ciliary body destruction procedures treat conditions such as glaucoma. Report both only when the operative documentation supports distinct services in the same session.

What postoperative care is included?

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.
