The 28-year-old Reichenbach's complaint is being investigated by cycling's Road Competitions' Commission according to those familiar with the matter.
The commission is empowered to make recommendations based on which cycling's governing body (UCI) can open disciplinary proceedings. The UCI has been contacted for comment.
Cyclingnews reported that Reichenbach had also filed a complaint with the Italian police.
"I'm filing a complaint against Gianni Moscon because he intentionally put me on the ground," Reichenbach was quoted as saying by Le Nouvelliste on Wednesday.
"It was intentional. Several riders saw the action and are ready to provide testimony on my behalf. He deliberately threw himself against me. On a descent, the accident could have had even more serious consequences. My team, FDJ, has encouraged me to file a complaint. They will support me."
Moscon, who wished Reichenbach a speedy recovery on Twitter, has denied causing the accident.
"It's not true. It's nothing to do with me. We were on a section of rough road and Reichenbach's hands slipped from his handlebars. I've never spoken to him in my life," Moscon, 23, told La Gazzetta dello Sport.
Reichenbach's team FDJ supported their rider's account of the crash.
"The crash has been caused by the dangerous behaviour of one of his opponents, Gianni Moscon," FDJ said on their Twitter account on Tuesday.
Team Sky issued a statement on Wednesday wishing Reichenbach a quick recovery.
"With regards to the circumstances around the crash, it is right and fair that the full facts are established and that those involved first have the opportunity to provide their own view through the proper channels," the statement added.
