Dr. Farid Fata, the cancer doctor accused of misdiagnosing patients and ordering unnecessary treatments is facing additional criminal charges.

Fata now faces additional health care fraud charges as well as a count of receiving 'kickbacks' and unlawful procurement of naturalization.

Fata is accused of misdiagnosing patients and ordering unnecessary treatments to enrich himself through Medicare and other insurance programs. The government says some patients were repeatedly exposed to powerful drugs despite having no cancer. Fata denies it. He's been in jail since August.

Fata owns and operates Michigan Hematology Oncology Centers (MHO) which has offices in Clarkston, Bloomfield Hills, Lapeer, Sterling Heights, Troy and Oak Park.

Doctors and nurses who worked with Fata told federal agents Fata often gave patients doses of medication they didn't need at toxic levels, treated them in office settings as opposed to hospitals and had what is referred to as "interns" or foreign doctors treat a high number of patients.
