Colorado is poised to give its health insurance exchange a new review. A Senate committee started work yesterday on a bill to order a more thorough audit for the state-run exchange, called Connect For Health Colorado. The audit was a priority for Republicans last year, but the proposal failed amid concerns that the exchange had already been audited and that an extra audit would be needless. But the GOP now controls the Senate and is expected to give approval to the expanded audit. The state-run exchange is entering its second year of selling insurance plans to comply with the new federal law.
