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.

How to choose

68801Punctum dilation
Use 68801 for dilation of the lacrimal punctum. Use 68840 when the procedure probes the canaliculus beyond the punctal opening.
68810Tear duct probing
Code 68810 addresses probing of the nasolacrimal duct; 68840 addresses probing of the lacrimal canaliculi.
68811Tear duct probing
Code 68811 is for nasolacrimal duct probing requiring general anesthesia. It is not the canalicular probing service reported with 68840.
68815Duct probing
Code 68815 includes insertion of a tube or stent during nasolacrimal duct probing. Code 68840 describes canalicular probing without that duct-stenting service.

68840 billing questions

When should 68840 be chosen over 68810?

Use 68840 when probing the lacrimal canaliculi. Code 68810 is for probing the nasolacrimal duct, a different part of the tear-drainage pathway.

Is irrigation separately reported with 68840?

No. Irrigation may be part of the canalicular probing service and is not separately reported as an additional service under this code.

How is bilateral canalicular probing reported?

Report modifier 50 for bilateral treatment. CMS pays the bilateral procedure at 150% of the single-side amount.

Are related postoperative visits included?

Yes. The 10-day global period includes related postoperative visits during those 10 days.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment is restricted for this code. Co-surgeons and team surgery are not permitted.

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.
