Revisional surgery to the aqueous shunt is reported through 66185
Revision of aqueous shunt to extraocular reservoir and includes
repositioning of the shunt deeper into the anterior chamber in order
to prevent corneal decompensation.
There are 3 codes for placement of an aqueous shunt without an
attached reservoir plate. These codes were created to keep pace with
newer technology in glaucoma surgery. Assignment of these codes
depends on the approach and type of device.
• 0191T. Placement within the trabecular meshwork of drainage
devices without reservoirs such as the Glaukos iStent Trabecular
Micro-Bypass Stent or Ex-Press Mini Glaucoma Shunt is reported
with Category III CPT code 0191T Insertion of anterior segment
aqueous drainage device, without extraocular reservoir; internal
approach, into the trabecular meshwork. This procedure is similar to
trabeculectomy with the exception, of course, that the device is
placed.
• 0253T. A new code was implemented on January 1, 2011, for the
drainage device placed into the suprachoroidal space. 0253T Insertion
of anterior segment aqueous drainage device, without extraocular
reservoir; internal approach, into the suprachoroidal space was created for devices such as the Glaukos iStent Supra, Transcend Cypass
Micro-Stent and Solx Deeplight Gold Micro-Shunt.
