In 2012, during the filming of 2 Broke Girls (2011)'s 2nd season, Moy unknowingly suffered a minor stroke in his sleep, waking to feeling weakness and motor skill loss in his right side. Driving himself to urgent care, doctors discovered bleeding in his brain, but no further deterioration. The loss of motor skills in Moy's right side required a year of physical therapy, and re-learning to write with his right hand, but he has since made a full recovery. Moy had kept the incident private from media until 2017.
