Carson had said private insurers should be a little more than "non-profit service organizations," with government capping their profit margins.

He said federal government could offer catastrophic care coverage paid for with taxes on insurers' profits.

Carson has called for government regulators to determine what providers can charge for care.

Early on as a candidate, he said he wanted to scrap Medicare and Medicaid, and spend the money on giving every American $2,000 a year for a health savings account.
