A second health insurance company doing business in Montana has been caught up in a massive fraud scheme that allegedly targeted Native American communities, according to State Auditor and Commissioner of Securities and Insurance James Brown.

Brown announced this week that his office helped stop more than $5 million in questionable insurance payouts by Mountain Health Co-Op.

The company is the second insurer affected by what investigators describe as a sophisticated operation that exploited federal Affordable Care Act (“Obamacare”) enrollment rules intended to benefit tribal members.

According to the Auditor’s Office, the scheme convinced Native Americans to drop their Medicaid coverage before enrolling them in Affordable Care Act plans using false information.

Victims were then transported to out-of-state addiction treatment centers, where insurers were allegedly billed for treatment that either never happened, wasn’t medically necessary, or was grossly inflated.
