What 68815 covers

An ophthalmologist probes the nasolacrimal duct to open an obstructed tear-drainage pathway and places a tube or stent to help maintain patency. The procedure is commonly used for persistent congenital nasolacrimal duct obstruction in children and may also be performed for acquired duct obstruction. It may include irrigation and is often performed in an operating room when a child requires anesthesia.

Choose this code when the probing includes placement of a tube or stent; probing without that placement is described by other codes in the family. Document the obstructed side, the probing, and tube or stent placement. Related postoperative visits during the 10-day global period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. For bilateral treatment, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this service, and co-surgeon and team-surgery billing 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.
