Jail Superintendent Dadhiram Maurya said that the amount would have been Rs 49,500.
The Talwars, who were acquitted by the Allahabad High Court on October 12 on charges of murdering their daughter Aarushi and their domestic help Hemraj, are likely to be released in the afternoon.
According to jail authorities, there has been a sudden rush of patients who are in a "hurry" to get their treatment done from them, the authorities said.
The Talwars, waiting to walk out of jail, perhaps to be virtually caged again inside the unrelenting media spotlight, have "refused to accept the remuneration" for the services rendered, said a jail official.
Jail doctor Sunil Tyagi has said the Talwars have assured the authorities that they would visit the prison every 15 days to conduct check-ups on inmates.
The Allahabad High Court in its verdict said neither the circumstances nor the evidence were enough to hold them guilty.
Aarushi Talwar was found dead in her bedroom in the Talwars' Noida home on May 16, 2008. Hemraj's body was found the next day from his room in the terrace.
