Which code is used for pulmonary perfusion imaging?

The code for pulmonary perfusion imaging is 78580. This procedure specifically involves the assessment of blood flow through the lungs using a radiopharmaceutical imaging agent, which allows healthcare providers to evaluate pulmonary function and identify conditions such as pulmonary embolism or other vascular anomalies in the lungs.

Understanding the purpose of this code is crucial; it reflects imaging performed when diagnosing or assessing the pulmonary system's perfusion status. The other codes related to this category generally refer to different imaging techniques or specific procedural nuances that do not directly correspond to the perfusion aspect in the lungs, thus isolating 78580 as the most accurate representation for pulmonary perfusion imaging.
