NEW YORK (CNNMoney.com) -- Ponzi scammer Bernard Madoff has been transferred to a medical facility at the prison where he's incarcerated in North Carolina, according to the Federal Bureau of Prisons.
Madoff has been at the medical center since his transfer on Dec. 18, said BOP spokeswoman Traci Billingsley.
The status of Madoff's health is unknown. Billingsley said she would not provide any details about his medical condition because prison policy considers that personal information.
In August, the BOP released a statement denying as untrue a press report saying that Madoff was terminally ill.
On Wednesday Billingsley said that the BOP was standing by its August statement.
Madoff's lawyer Ira Lee Sorkin had no comment.
Madoff, 71, pleaded guilty in March to 11 counts related to running the most massive Ponzi scheme in history and was sentenced to 150 years.
Shortly after his sentencing in New York, Madoff was transferred to a medium security federal prison in Butner, N.C. The medical center is located within the prison complex.
