Question: My physician performed a laser trabecu-loplasty for glaucoma in a patient's left eye. One week later the patient returned for the physician to monitor his progress, and my physician decided the procedure was unsuccessful. He performed an iridotomy in a second attempt to lower the intraocular pressure of the patient's left eye. Which modifier do I need to append to the iridotomy to be reimbursed? Anonymous Subscriber
