Two Houston area residents have been ordered to federal prison after admitting to paying kickbacks to marketers and a physician. Joseph Nwankwo, 59, Houston, and Stacey Ajaja, 51, Richmond, pleaded guilty Nov. 2, 2022, and March 11, 2022, respectively, to conspiracy to defraud the United States and paying and receiving illegal healthcare kickbacks. Nwankwo was ordered to serve 36 months in federal prison, while Ajaja received a 14-month-term of imprisonment. Both must also serve three years of supervised release following completion of the prison terms. Nwankwo must pay $1,218,615.13 in restitution to Medicare, while Ajaja was ordered to pay $238,164.69. Nwankwo and Ajaja co-owned Hefty Healthcare Services Inc. At the time of their pleas, they admitted that from 2014 through 2016, both obtained patient referrals by paying marketers and patients. Nwankwo further admitted to bribing a physician to authorize medically unnecessary home health services for Hefty patients. Nwankwo and Ajaja were permitted to remain on bond and voluntarily surrender to a US Bureau of Prisons facility to be determined in the near future.
