Nick Gerhart, the Iowa insurance commissioner, will be leaving that post Dec. 23, according to the Iowa Insurance Division.

Doug Ommen, deputy commissioner, will be the interim commissioner, officials say.

Gerhart is resigning because his family is expecting a fourth child, and he has not committed to any other future job, a representative said.

Gerhart has a bachelor’s degree from the University of Northern Iowa and a law degree from St. Louis University. He worked in compliance for insurance companies before becoming the Iowa commissioner.

While serving as the Iowa commissioner, Gerhart expressed concerns about potentially misleading annuity advertising and oversaw the state’s efforts to adapt to the Affordable Care Act. Iowa did not set up a state-based ACA public health insurance exchange, but it did take ACA Medicaid expansion money.

Iowa also helped managers of HealthCare.gov, the federal ACA exchange enrollment and exchange account administration system, promote the program.

Gerhart faced an early sign of problems in major ACA coverage expansion programs when CoOportunity, a nonprofit, member-owned carrier started with ACA Consumer Operated and Oriented Program startup loans, failed suddenly in late 2014. CoOportunity was the first CO-OP to fail. Since then, many others have shut their doors.
