OMAHA, Neb. (AP) — An Omaha man has been sentenced to nearly four years in prison and ordered to pay more than $809,000 in restitution for Medicare fraud he conducted in 16 states. Federal prosecutors say Nereus Sutko visited assisted-living facilities, retirement centers and low-income housing complexes in Nebraska, Iowa, Kansas, Missouri and 12 other states. Prosecutors say he held pizza and ice cream parties at the facilities and convinced elderly people to sign up for Medicare-funded products he never delivered. Prosecutors say Sutko was paid more than $1.8 million by Medicare, Nebraska Medicaid and Iowa Medicaid, much of it based on fraudulent claims. Sutko pleaded guilty in December to health care fraud.
