One of the biggest Medicare Advantage fraud cases has hit a snag, with government officials saying they don’t have access to a key witness.

Elevance Health is blocking the deposition of Peter Haytaian, an outgoing executive who previously oversaw the health insurer’s Medicare Advantage plans, Department of Justice attorneys said this week in a letter to a judge. The letter also revealed how Elevance announced Haytaian’s departure right after DOJ first asked to depose him.

The dispute underscores the high stakes of the lawsuit, which the DOJ initiated in 2020. It also adds to the wide-ranging scrutiny facing Elevance’s private Medicare plans for seniors, which generated more than $40 billion of revenue last year.
