CommInsure has rejected allegations that documents stored in its medical claims tracking system were deliberately tampered with or deleted.

Australian Securities and Investments Commission investigations and internal probes uncovered no proof to support those allegations, the life insurer says in response to a question from a parliamentary joint committee inquiry into the industry.

“Multiple investigations into the allegation that documents were missing or altered have been completed [and] CommInsure is satisfied there is no evidence to substantiate it,” according to parent company the Commonwealth Bank.

It says access to edit medical opinion information stored in the medical officers’ referral database was restricted to medical officers and system administrators.

The database is no longer active, having been replaced by one with audit functionality.
