The Wales forward has until 6pm on Tuesday to respond to the charge after the FA's three-man disciplinary panel studied footage of the incident.
Bellamy appeared to punch De Guzman off the ball, and could face a three-match ban if found guilty.
It was missed by referee Andre Marriner and his officials, but caught on video.
A statement said on the FA's official website said: "Under a new pilot project in Premier League matches this season, if an incident has not been seen by the match officials, a three-man panel of former elite referees will be asked by The FA to review it and advise what, if any action, they believe the match referee should have taken had it been witnessed at the time.
"For an FA charge to follow, all three panel members must agree it is a sending-off offence. In this instance, the panel were of the unanimous decision that it was an act of violent conduct.
"The panel were also asked to review an incident involving Manchester City’s Yaya Toure during the game against Norwich City on Saturday 8 February 2014. In this instance, the panel were not of the unanimous decision that it was an act of violent conduct.
