CPT® Code 78587

Deleted

The procedure described by CPT® Code 78587 refers to pulmonary ventilation imaging using an aerosolized radioactive gas. This imaging technique involves the patient inhaling and exhaling a radioactive substance, which is then monitored by a specialized camera capable of detecting the emitted radioactive particles. The primary purpose of this procedure is to visualize the airways and assess lung function by identifying any potential obstructions or abnormalities within the respiratory system. During the imaging process, multiple projections are captured, including anterior, posterior, and lateral views, which provide comprehensive insights into the patient's pulmonary status. The repeated inhalation and exhalation of the radioactive gas during the imaging allows for a thorough evaluation of the ventilation patterns in the lungs, aiding physicians in diagnosing various respiratory conditions.
