CPT® Code 78660

Radiopharmaceutical dacryocystography is a specialized radiologic examination that focuses on the nasolacrimal ducts, commonly known as tear ducts. This procedure is conducted to evaluate conditions associated with excessive tearing and to assess the patency, or openness, of the lacrimal drainage system, as well as to identify any underlying pathologies. During the examination, a radioisotope labeled medium, which may include types such as Indium or Technetium 99m, is injected into the lacrimal system. Prior to the injection, anesthetic drops are applied to the eyes to minimize discomfort. The lacrimal canaliculi, which are small channels that drain tears from the eyes, are then cannulated to facilitate the introduction of the radioisotope. Following the injection, a series of radiographic images are captured at various oblique angles to visualize the lacrimal pathways effectively. The physician analyzes these images for signs of abnormalities, including stenosis (narrowing of the ducts), blockages, growths, or the presence of fistulae (abnormal connections). It is important to note that this CPT® code specifically reports the radiologic component of the dacryocystography procedure, and a comprehensive written report detailing the findings is generated for further evaluation and management.
