What 68840 covers

An ophthalmologist, often an oculoplastic surgeon, passes a probe through the lacrimal punctum into a canaliculus to assess or relieve an obstruction. Irrigation may be performed as part of the service. The procedure is used for problems such as tearing associated with suspected canalicular narrowing or blockage, and may be performed in an office procedure room or an operating room depending on the patient and clinical circumstances.

Report 68840 when the treated structure is a lacrimal canaliculus, rather than the nasolacrimal duct. Document the affected side, the clinical indication, and the probing performed; irrigation does not require a separate code. CMS assigns a 10-day global period, so related postoperative visits during that period are included. For bilateral treatment, modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

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.

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.
