The Rugby Football Union (RFU) said on Monday that the 28-year-old Green will appear before an independent disciplinary panel on Wednesday.
According to RFU guidelines, if a player is found guilty of biting the starting point for a suspension is 12 weeks for a low-end offence.
Green has started all of Newcastle's 17 Premiership matches this season but could miss the last five games in their battle to avoid relegation.
