CPT® Code 66850

The procedure described by CPT® Code 66850 involves the removal of lens material from the eye using a technique known as phacofragmentation, which can be performed mechanically or ultrasonically, commonly referred to as phacoemulsification. This surgical intervention is typically indicated for patients with cataracts or other conditions that cause opacification of the lens, leading to impaired vision. During the procedure, the surgeon utilizes an operating microscope to visualize the eye, ensuring precision and safety. Access to the anterior chamber of the eye is achieved through the creation of one or more small incisions, known as paracenteses, using a needle or blade. A specialized probe is then inserted through these incisions to break up the lens material using ultrasound energy. Following the fragmentation of the lens, an irrigation and aspiration tool is employed to remove the dislodged lens pieces from the eye. The procedure requires careful monitoring of the intraocular pressure to maintain the stability of the anterior chamber, and any necessary sutures may be placed to secure the incisions post-operation. This technique is essential for restoring vision in patients suffering from cataracts and is a common practice in ophthalmic surgery.
