TOPEKA, Kan. (AP) — The new acting inspector general for the state’s privatized Medicaid program has abruptly resigned amid questions about his appointment and lack of confirmation by the Kansas Senate.

Kansas Department of Health and Environment spokeswoman Sara Belfry said Phil Hermanson  stepped down Friday afternoon.

Belfry said Hermanson did not provide a resignation letter. Hermanson did not immediately return a telephone message left at his Wichita home.

Hermanson began work in April, charged with identifying fraud in the state’s Medicaid system known as KanCare. He has no investigatory or auditing expertise.

But his duties in the $77,000 job were limited because he hasn’t been confirmed. The Legislature is out of session until next year, but a Senate committee can give the go-ahead for appointees to serve until lawmakers convene again.
