What 65855 covers

An ophthalmologist directs laser energy to the trabecular meshwork, the eye’s drainage tissue, to improve aqueous outflow and reduce intraocular pressure. The procedure is commonly used for open-angle glaucoma and may be performed with selective or argon laser in an ophthalmology office or an outpatient facility. The treated eye and the laser procedure performed should be clear in the operative documentation.

Report 65855 for laser trabeculoplasty, distinguishing it from incisional procedures such as goniotomy or trabeculotomy. Related postoperative visits are included in the 10-day global period. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral treatment, modifier 50 is paid at 150%. Medicare does not pay for an assistant at surgery; co-surgeon and team-surgery payment requires supporting documentation.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

65855 billing questions

How is laser trabeculoplasty different from goniotomy?

65855 describes laser treatment of the trabecular meshwork. Goniotomy uses an incisional approach to open the drainage angle.

How should bilateral treatment be reported?

For treatment of both eyes, report the procedure with modifier 50. CMS pays bilateral procedures at 150%.

Are related postoperative visits separately payable?

Related postoperative visits during the 10-day global period are included in the procedure.

What happens when another procedure is performed in the same session?

The highest-valued procedure is paid in full. Other procedures performed in that session are subject to the standard multiple procedure reduction.

Can an assistant surgeon be reported?

Medicare does not pay an assistant at surgery for this code. Co-surgeon or team-surgery payment requires supporting documentation.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
