Disgraced former USA Gymnastics doctor Larry Nassar, who is currently serving a decades-long sentence in federal prison for sexual abuse, has been delinquent in his payments toward court-ordered criminal penalties, according to a new court filing.

A motion filed July 28 by the US Justice Department said that since Nassar's incarceration, he had received deposits into his inmate trust account that reached $12,825, including two stimulus checks totaling $2,000.

As of July 28, Nassar had $2,041.57 in his account, according to the motion. It is unclear where the additional money – more than $10,000 – went.

In addition, he was sentenced on Jan. 24, 2018, to up to 175 years in Michigan state prison after pleading guilty to seven counts of criminal sexual conduct. At the sentencing, 156 victims spoke, recounting similar stories of how they went to Nassar to receive treatment for sports injuries only to be sexually assaulted and told it was a form of treatment.

He is currently serving his federal sentence in the US Penitentiary in Sumterville, Florida.

Despite having money in his account, Nassar has only paid $300 toward the more than $62,000 he was ordered to pay, according to the motion. He was ordered to pay $57,488.52 in restitution to five victims in the child pornography case, along with an extra $5,000 for a special assessment fee pursuant to the Justice for Victims of Trafficking Act of 2015, the motion read.

All of Nassar's payments toward his restitution have been "in the form of the minimum $25.00 quarterly payments based on his participation" in the Inmate Financial Responsibility Program, the motion said.

"In other words, Nassar has paid approximately $8.33 toward his criminal monetary penalties per month," the motion said.

The motion requests that the court order the Bureau of Prisons to turn over the funds in his account, up to $62,488.52, to be applied to his outstanding restitution and special assessment debt.

Included with the motion was a letter from the US Marshal Service on July 22 to the warden at US Penitentiary Colemen II in Sumterville, requesting that "all outbound financial transactions and withdrawals from his trust account be frozen pending further order of this Court," the motion reads.

The Bureau of Prisons told CNN that it "is committed to taking all appropriate steps to help ensure that inmates meet their financial obligations, including court-ordered payments to compensate victims. As part of that process, it regularly analyzes and monitors inmate accounts. BOP also partners with other law enforcement agencies and regularly notifies relevant authorities – such as the U.S. Marshals and US Attorneys' offices – when it identifies funds that are appropriately subject to seizure. BOP took such steps here. As reflected on the public docket, the government has asked the court to order that all funds in an inmate's account be turned over to satisfy a restitution judgment. The BOP will continue to examine its policies in an effort to do all it can to help ensure that inmates meet their fundamental financial obligations."
