What 66030 covers

An ophthalmologist typically performs this procedure by placing a therapeutic medication into the anterior chamber, the fluid-filled space between the cornea and iris. It may be performed in an office or facility when the treatment is intended for that chamber; the selected code depends on the injection site and material, not simply on the fact that an eye injection occurred. This differs from an injection of air or liquid and from medication delivered into the vitreous or another tissue plane.

Report the service for the treated eye and document the medication, anterior chamber route, clinical indication, and laterality. CMS assigns a 10-day global period, so related postoperative visits during that period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral reporting with modifier 50, payment is 150%. Assistant-at-surgery payment is restricted, and 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.

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.
