In remarks to the ferghana.ru information website, Bermet Akaeva questioned the authenticity of the documents the NBC television network used for its report.
NBC on October 30 said it had obtained an FBI report saying that an international investigation was under way "targeting as many as 175 entities associated with the Akaev organization."
Kyrgyz authorities have not reacted to the NBC report, which the AKIpress news agency carried on October 31.
Kyrgyz prosecutors have been giving contradicting indications as to whether Akaev is under criminal investigation for alleged financial misdeeds.
Akaev ruled Kyrgyzstan from 1990 until March 2005, when street protests forced him to flee to Russia.
