In 2015, Koch became gravely ill and was hospitalized. On January 26, 2015, at the
RealScreen Summit in Washington, D.C., he went to
George Washington University Hospital with a 102 degree temperature. Two days later, he was put into a
propofol-induced coma. The following day, he was in full-blown
septic shock and his hands and feet were turning blue. Koch's hands and feet became necrotic, and he eventually lost the bottom part of his right leg, parts of his fingers on his right hand, and all of his toes. In April 2015, after delaying the amputation of his left hand, Koch returned to Los Angeles and met UCLA's Dr. Kodi Azari, who was heading up hand transplant trials. In October 2016, a donor became available, and Koch underwent a 17-hour hand transplant surgery. == Selected filmography ==
