CPT® Code 32220

The procedure described by CPT® Code 32220 refers to total pulmonary decortication, which is a surgical intervention aimed at removing a thickened layer of fibrin, commonly known as the rind or peel, from the outer pleural surface of the lung. This thickened fibrin layer can restrict the lung's ability to expand fully, leading to compromised respiratory function. During the procedure, the surgeon makes a posterolateral incision in the chest, typically at the fifth or sixth intercostal space, to gain access to the lung. Once exposed, the surgeon carefully incises the thickened fibrin layer to identify the appropriate decortication plane. The fibrin is then meticulously grasped and dissected away from the underlying visceral pleura, ensuring that all areas of the lung encased by the fibrin are addressed. Following the decortication, one or more chest tubes may be placed to facilitate drainage, and the incision site is subsequently closed. It is important to note that if only a portion of the lung is involved, CPT® Code 32225 should be utilized instead.
