What 78580 covers

This nuclear medicine study maps blood flow through the lungs after intravenous administration of radiolabeled particles. Gamma-camera images show how perfusion is distributed across the lungs. Common reasons include suspected pulmonary embolism, assessment of pulmonary vascular perfusion, and evaluation of functioning lung before selected thoracic surgery. A nuclear medicine technologist acquires the images, which a radiologist or nuclear medicine physician interprets in a hospital or outpatient imaging setting.

Report 78580 for perfusion imaging alone. When ventilation and perfusion imaging are both performed, 78582 describes the combined examination. Documentation should support the clinical indication, radiopharmaceutical administration, images obtained, and interpretation. The service has separately priced professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and billing without either modifier represents the global service.
