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.

68815 billing questions

When should 68815 be chosen over 68810?

Use 68815 when nasolacrimal duct probing includes insertion of a tube or stent. Probing without tube or stent placement is reported with 68810.

Does anesthesia determine whether 68815 applies?

No. The distinguishing service is insertion of a tube or stent during probing, not the anesthesia used. The documentation should support the stent placement.

Can both sides be reported?

For bilateral treatment, report modifier 50; CMS pays the bilateral procedure at 150%. Document the procedure on each side.

Are postoperative visits separately reported?

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

Can an assistant or co-surgeon be billed?

Medicare does not pay an assistant at surgery for 68815. 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.
