The Australian Rugby Union has confirmed that Healy will have to appear before a hearing on Thursday, accused of biting Western Force's scrum-half Brett Sheehan.
"Healy has been cited under Law 10.4.m Acts contrary to good sportsmanship, a player may not bite an opponent," a statement said.
"The incident occurred in the 17th minute."
Healy's future participation in the Lions' tour is already under threat because of the injury which saw him taken to hospital for an X-ray - although initial reports point to an ankle sprain rather than anything more serious.
The Lions have announced that England prop Alex Corbisiero will fly from Argentina to Brisbane and join up with the team as injury cover for Healy.
Ulster winger Tommy Bowe was among the try scorers as the Lions crushed Western Force 69-17 - the tourists ran in nine tries against their spirited, but outclassed opponents at Patersons Stadium.
The total included two scores from captain Brian O'Driscoll, as well as efforts from Jonathan Sexton, Tom Croft, Jamie Heaslip, Mako Vunipola, Bowe, Owen Farrell and Geoff Parling - while full-back Leigh Halfpenny gave a goal-kicking masterclass.
O'Driscoll led by example as the Lions got their nine-game Australian tour schedule off to an ideal start with a dominant and hugely encouraging victory.
The captain, making the first appearance of his fourth successive Lions tour, had any number of willing workers alongside him - most notably the sublime Sexton and strong-running flanker Sean O'Brien.
Halfpenny, this year's Six Nations player of the tournament, booted all nine conversions and two penalties for 24 points and a 100% record.
The Force replied with touchdowns by forwards Richard Brown and Lachlan McCaffrey, converted by scrum-half Brett Sheehan who also landed a penalty, but they had no answer to a relentless Lions side which never took its foot off the accelerator.
Head coach Warren Gatland will now turn his attention to what promises to be a far sterner encounter against Queensland Reds in Brisbane on Saturday.
