CPT® Code 65220

The procedure described by CPT® Code 65220 involves the removal of a foreign body from the external eye, specifically the cornea, without the use of a slit lamp. The cornea is a crucial part of the eye, serving as the transparent layer that covers the front of the eye and plays a significant role in focusing light onto the retina. When a foreign object, such as dust, metal, or other debris, becomes lodged in the cornea, it can cause discomfort, visual disturbances, and potential damage to the eye. To perform this procedure, the physician first instills anesthetic drops into the eye to minimize pain and discomfort during the removal process. Following this, the physician assesses the patient's visual acuity and may conduct a funduscopy to accurately locate the foreign body. In cases where the foreign body is superficial, it can often be removed using a moistened cotton swab. For embedded foreign bodies, the physician utilizes specialized instruments such as an ophthalmic spud or needle, which allow for precise removal under magnification. If the foreign body is metallic and has resulted in a rust ring, the physician will employ a corneal burr to excise the rust-impregnated corneal tissue. After the foreign body is successfully removed, the eye is typically flushed with saline solution to eliminate any remaining fragments. The resulting corneal defect is treated similarly to a corneal abrasion, which may involve the application of antibiotic ointment and the use of an eye patch to promote healing. It is important to note that CPT® Code 65220 is specifically used when the foreign body is removed without the assistance of a slit lamp, while CPT® Code 65222 is designated for cases where a slit lamp is utilized during the procedure.
