France team doctor Franck Le Gall had said on Thursday that Ribery played as a substitute in the German Cup final on May 17 with pain-killing injections despite having suffered from back trouble for several weeks.
Bayern's doctor Hans-Wilhelm Mueller-Wohlfahrt rejected French claims it was his treatment that ruled the winger out.
Ribery was dropped from the France squad days before the tournament started after failing to recover from a back injury that had troubled him towards the end of the season.
"He (Ribery) was evidently told not to be treated by Mueller-Wohlfahrt," said a statement issued through the lawyers of the German doctor, who is at the finals in Brazil for his country's national team.
"He (Mueller-Wohlfahrt) assumes that had he (Ribery) been treated there would have been the possibility for him to play at the World Cup."
