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

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.
