State regulators are examining a $1.5 million proposal by an Oregon insurer to take over a portion of Montana's third-largest health insurance company as part of a government anti-trust settlement. Commissioner of Securities and Insurance Monica Lindeen has scheduled a hearing Tuesday on the proposal by PacificSource Health Plans to buy New West Health Service's commercial business. The hearing will examine whether the deal is fair and protects the estimated 9,000 New West policyholders who will be affected, said Lindeen spokesman Lucas Hamilton. The hearing will include a public comment period.
