CPT® Code 67121

The procedure described by CPT® Code 67121 involves the removal of implanted material from the posterior segment of the eye, which is a critical area that includes various optical structures. The posterior segment is defined as the region behind the anterior hyaloid membrane and encompasses the vitreous humor, retina, choroid, and optic nerve. This procedure is typically indicated when there is a need to extract materials that have been implanted either extraocularly or intraocularly. Commonly, the materials that are removed during this procedure include silicone oil, which is often used in retinal surgeries, and displaced intraocular lenses, which may have shifted from their intended position. Notably, this procedure is performed without the need for a vitrectomy, which is a more invasive surgical technique that involves the removal of the vitreous gel from the eye. The goal of this procedure is to restore normal anatomical function and improve visual outcomes by eliminating foreign materials that may cause complications or impair vision.
