One of the city's largest employers, from 2013-2017, was Serco. The British-based company was awarded a five-year contract in 2013 to manage the implementation of the Patient Protection and Affordable Care Act. As a result of the contract, Serco opened its Affordable Care Act application processing facility in Wentzville in August of that same year in the building that was formerly home to the US Fidelis call center. The Wentzville Serco facility attracted national attention in 2014 after whistle-blower allegations revealed that workers spent large amounts of time sleeping or playing games due to lack of work.     At its peak, Serco employed approximately 1,500 employees in Wentzville. In 2018, Serco announced its closure of the Wentzville processing center to coincide with the end of its five-year contract with the Centers for Medicaid and Medicare Services. Closing of the facility resulted in a loss of 850 jobs.
