West Des Moines-based CoOportunity Health will withdraw from the Iowa Health and Wellness Plan next month, and the state has arranged for its 9,700 members to receive coverage through another component of the bipartisan-approved plan, the Iowa Department of Human Services announced.  The program, available to eligible low-income Iowans, provides access to health care while offering incentives for members to improve their overall health. Leigh McGivern, a CoOportunity spokeswoman, said the cooperative had financial losses from the high utilization of health care services by the Medicare expansion program, primarily the IowaCare program. "As a nonprofit, member-governed new health plan, we cannot ask our 85,000 other members to pay higher rates to subsidize the 9,700 (Health and Wellness) members," she said in an email. CoOportunity, a new insurance cooperative that began operations a year ago, will leave the Marketplace Choice Plan at the end of November. Coventry Health Care of Iowa, Iowa's other Marketplace Choice provider, will accept all new Marketplace Choice enrollees in December while the state explores options.
