What 66020 covers

An ophthalmologist uses this procedure to introduce air or a nonmedicated liquid into the anterior chamber, the space between the cornea and iris. The material may be placed to support or restore the chamber in an anterior-segment problem. The code identifies what is introduced, not an injection of medication. The service is typically performed by an ophthalmologist in an office, ambulatory surgical center, or hospital setting.

Select this code when the injected material is air or nonmedicated liquid; use 66030 when medication is injected into the anterior chamber. Document the eye treated, the material introduced, the indication, and the procedure performed. Medicare 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 performance, 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.

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.
