"Sternotomy were performed. ICD was excised from left deltopectoral pocket and placed outside the body. ICD leads were cut at the level of the innominate vein in the deltopectoral pocket. Right subclavicular incision was reopened and Hemashield graft exposed. As soon as cardiopulmonary bypass was initiated, the Impella 5.0 was pulled out, and Hemashield graft was stapled off. The donor heart came to the field. The interatrial septum was inspected; there was no PFO. The LAA of the donor heart had been opened on procurement and had been closed. The heart was then implanted in the usual fashion." Are codes 33945, 33944, 33241, 33243, and 33992 correct? Impella was inserted two days prior via Hemashield conduit. If code 33992 is not correct, how would this be coded? I'm not sure of the documentation requirements for 33944.
