"All [claims data] is in Aetna's possession, custody, and control and readily accessible to Aetna as TPA for the Kraft Heinz plans," the complaint said. "If it is not, then Aetna is not in compliance with its regulatory obligations. Aetna's failure to give Kraft Heinz its own standard transaction information violates Aetna's fiduciary duties." Kraft said it is looking to be reimbursed for any losses stemming from the alleged breach in fiduciary responsibilities by Aetna, along with any profits that were made by the payer through the alleged practices. Kraft is also seeking a preliminary injunction to compel Aetna to provide complete claims data. Becker's has reached out to Aetna for comment and will update this article if more information becomes available.
