The National Prosecuting Authority will have a chance to examine former president Jacob Zuma's medical records.
Zuma's special plea hearing will be postponed to the 20 and 21 September.
"We can confirm that the special plea hearing relating to Mr Zuma's case will be postponed virtually by consent of all the parties to September 20 and 21, to enable the state-appointed medical team of specialists to consider the medical evidence in co-operation with Mr Zuma’s medical team," said National Prosecuting Authority spokesperson Mthunzi Mhaga.
He said the state would give no further details on the matter as Zuma’s medical records were confidential.
Zuma was this week placed on medical parole, 58 days after he was admitted as an inmate at the Estcourt Correctional Services facility in KwaZulu-Natal.
In the criminal case, he is facing 16 counts of fraud, corruption, money laundering and racketeering and his co-accused, the French arms company Thales, is facing four counts.
Among the allegations is that the former president received an annual kickback of R500,000 paid through his former financial adviser Schabir Shaik in exchange for shielding Thales from an investigation into the controversial arms deal.
The corruption trial, which involves Zuma and French arms company, Thales, is set to resume on 9-10 September after it was postponed by presiding Judge Piet Koen due to former president being in hospital.
