What 68810 covers

An ophthalmologist passes a probe through the tear drainage pathway to open or assess an obstruction in the nasolacrimal duct. Irrigation may be used to check or restore flow. A common situation is treatment of persistent tear-duct blockage in an infant; the procedure may also be performed for duct obstruction in other patients. The service is commonly furnished in an office or outpatient setting.

Report 68810 for simple probing, with or without irrigation, when the service does not require general anesthesia and does not include tube or stent placement or balloon catheter dilation. The note should identify the treated side, the obstruction or reason for probing, the instruments and technique used, and whether irrigation was performed. This minor procedure has a 10-day global period, which includes related postoperative visits during that period. 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 other procedures are subject to a 50% reduction. Medicare does not pay an assistant at surgery; 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.
