The man known as "Joe Exotic" will be resentenced later this month on two federal murder-for-hires charges.
Joseph Maldonado-Passage's lawyers argued last year that the two counts should have been grouped together at sentencing, and it could have lowered his overall sentence by more than four years.
Court documents filed Monday show that Maldonaldo-Passage will be resentenced on Jan. 28.
Maldonaldo-Passage announced in November that he has prostate cancer. A motion filed in federal court in December says he is delaying treatments until after his resentencing on convictions for a murder-for-hire plot and violating federal wildlife laws.
He was transferred weeks later from a federal medical center in Fort Worth, Texas, to a federal medical center in Butner, North Carolina.
Federal officials have said Maldonado-Passage will need up to eight weeks of radiation treatments and would be unable to travel during the treatments.
The motion said Maldonado-Passage was told by his physicians that his condition can currently be safely monitored.
