trabeculoplasty

DEFINITION of trabeculoplasty

trabeculoplasty is typically performed at a slit lamp using a gonioscopy lens to deliver laser energy to the trabecular meshwork in the anterior chamber angle, aiming to increase outflow and lower IOP. Common clinical types include argon laser trabeculoplasty (ALT) and selective laser trabeculoplasty (SLT), both used to increase aqueous outflow in open-angle glaucoma. ​

CPT/HCPCS Code(s):

65855 - Trabeculoplasty by laser surgery, 1 or more sessions (defined treatment series)

• Explanation: This code covers the use of a laser (SLT or ALT) to treat the trabecular meshwork. The code description “1 or more sessions” means that if the procedure is performed in stages on the same eye within the global period, it is only billed once.
• wRVU: 4.14
• Global Period: 010 days (Minor surgery).
• Assistant Payable: No.
• Bundling & NCCI Edits: * Inclusives: Includes internal eye exam (gonioscopy) and local anesthesia.
• Mutually Exclusive: Generally cannot be billed with other glaucoma surgeries (like 66170 trabeculectomy) in the same eye on the same day.

ETYMOLOGY of trabeculoplasty

latin “trabeculoplasty” breaks down as trabecul(o)- (trabecula; here referring to the trabecular meshwork) + -plasty (plastic surgery/reshaping).​

Merriam-Webster defines it generally as plastic surgery of a trabecula and, specifically in Ophthalmology, as laser surgery creating small openings in the trabecular meshwork to reduce IOP in open-angle glaucoma.
