The charge stems from a Sept. 4, 2009 fight outside a Seaside Heights nightclub in which Ortiz-Magro knocked another man unconscious.
The fight was shown during an episode of the popular MTV reality show's first season.
Ortiz-Magro was arraigned on the charge Monday in state Superior Court in Toms River. The charge carries a potential prison term of up to five years.
The alleged victim, 26-year-old Stephen Izzo of Berkeley Township, also has filed a lawsuit against Ortiz-Magro, MTV and the show's producers.
Superior Court Judge Stephanie Wauters scheduled a status conference for March 7.
