Rison, who was indicted in August 2011 and pleaded guilty April 25, was also given five years' probation, The Atlanta Journal-Constitution reported.
U.S. District Judge Frederick Martone in Phoenix ordered Rison to pay $1,000 a month in addition to his regular payments of $2,358 a month, said Katherine Harris, a spokeswoman for the U.S. Department of Health and Human Services.
Zeva Pettigrew, assistant special agent in charge of HHS's Los Angeles office, said Rison had originally been ordered to pay child support for a son in May 1999 and has made only two payments since November 2001. He was not married to the child's mother.
Pettigrew said the payments had been made as a result of withholdings by Rison's employers and he had not made any voluntary payments.
The Journal-Constitution said Rison had made at least $19 million in base salaries and signing bonuses during his 12-year NFL career.
He has said he had little of the money left.
Rison played for the Atlanta Falcons 1990-94. He played for the Green Bay Packers in 1996, when the Packers went on to win the Super Bowl, and appeared in the Pro Bowl five times.
