Cash started playing Michael on General Hospital on a recurring basis in March 2002, and went on contract in April 2005. He was released from his contract in April 2008, as show executives wanted to explore recasting and ultimately aging the character of Michael.[2] As a result, Cash's Michael suffered a gunshot wound to the head and fell into a "permanent" coma. Cash last aired on May 16, 2008, as Michael was checked into a facility for his state.
Cash returned to General Hospital on December 29, 2008, for one episode, when his TV parents Sonny and Carly Corinthos visited Michael at the hospital on his birthday.
Cash was also featured in the 2004 hit Fat Albert and appeared on Sabrina the Teenage Witch as Billy.
