Aetna Backtracks On ACA Expansion, Dealing A Blow To Obamacare

Aetna, one of the largest healthcare providers to participate in Affordable Care Act plans, said Tuesday it will re-evaluate its participation in the 15 state exchanges where it offers coverage. It canceled plans to expand into five more states.

The insurer says it faces an estimated $300 million in losses on its Obamacare business, joining other major insurers concerned with the ACA's viability.
