Healy was initially charged with kneeing the French international hooker although that wasn't proven and the charge was amended by World Rugby to: "dangerous charging or obstructing or grabbing of an opponent without the ball, including shouldering".
Healy appealed against the amended charge, allowing him to play in the return European Cup fixture in Dublin on Saturday, which Toulon won 20-16, thus eliminating Leinster from the competition.
His appeal hearing will take place by video conference on Wednesday.
If unsuccessful he will miss Pro12 matches against Munster and Connacht.
