CPT® Code 68850

Dacryocystography is a specialized radiologic examination that focuses on the nasolacrimal ducts, commonly known as tear ducts. This procedure is performed to evaluate conditions such as excessive tearing and to assess the patency, or openness, of the lacrimal drainage system, as well as to identify any underlying pathology. The examination involves the injection of a contrast medium, which enhances the visibility of the lacrimal pathways during imaging. Dacryocystography is particularly useful for both pre-operative and post-operative evaluations, allowing healthcare providers to gather critical information regarding the functionality of the lacrimal system. Prior to the procedure, patients may undergo panoramic radiography of the face, which can be reported separately. The procedure begins with the instillation of anesthetic drops into the eyes to minimize discomfort. Following this, the lacrimal canaliculi are cannulated, allowing for the injection of either a water-soluble or oil-based contrast medium. Radiographic images are then captured at various oblique angles to provide a comprehensive view of the lacrimal pathways. It is important to note that CPT® Code 68850 specifically reports the injection of the contrast medium and the necessary cannulation involved in this procedure, rather than the imaging itself.
