Reimbursement for Goniotomy or Trabeculotomy ab Interno

Trabeculotomy ab interno is an ophthalmic surgical procedure to incise and partially remove trabecular meshwork to create an opening into Schlemm’s canal by way of the anterior chamber angle.  The procedure is carried out by means of an ab interno approach from inside the anterior chamber under indirect visualization with a goniolens.  So, the longstanding term for this procedure is Goniotomy.
