  • YAG Laser When Performed in Global Period

    Which is the correct modifier to use for a YAG laser capsulotomy, CPT code 66821, performed during the post-op period of the initial cataract surgery, 78 or 79?

    If the YAG laser is performed in the same eye as the cataract surgery use modifier -78 since the laser is related to the cataract surgery. If the laser was performed in the other eye, report modifier -79 as it is unrelated.
