CPT® Code 0445T

Subsequent placement of a drug-eluting ocular insert under one or more eyelids, including re-training, and removal of existing insert, unilateral or bilateral

The procedure described by CPT® Code 0445T involves the subsequent placement of a drug-eluting ocular insert under one or more eyelids, which may be performed unilaterally or bilaterally. This insert is a specialized medical device designed to deliver medication directly to the ocular surface. The insert is thin, sterile, and multi-layered, consisting of an inner polymeric support that provides structural integrity, while the outer layer is infused with a specific drug or medication intended for therapeutic use. The device is strategically placed beneath the eyelid, resting on the conjunctiva, where it can effectively release the medication through controlled diffusion, facilitated by the permeation of lacrimal fluid through the outer membrane. During the procedure, the healthcare provider measures the intercanthal distance to select the appropriate size of the ocular insert. A topical ophthalmic anesthetic may be applied to minimize discomfort during the insertion process. The upper eyelid is then manually retracted to allow for the placement of the insert in the upper fornix, followed by the retraction of the lower eyelid, either manually or with the aid of a scleral depressor, to position the lower half of the insert in the lower fornix. It is important that a portion of the insert remains visible in the medial canthus for ease of management. After the placement, the patient receives instructions on how to care for the insert and manage any slight displacements that may occur. In cases where an existing insert needs to be removed, the procedure involves retracting the lower lid to expose the bottom half of the insert, allowing the healthcare provider to grip the exposed ring and gently pull it from the eye. This code specifically captures the nuances of re-training the patient on the care and management of the insert, as well as the removal and replacement of the device to ensure continued medication dosing.
