Mr. Yusuf, 54, took over the state-run health insurance provider on July 29, 2016.
But his reign at the health ministry parastatal has been fraught with allegations of fraud.
The suspension came weeks after the Senate launched investigations into his activities as the NHIS chief.
The lawmakers accused Mr. Yusuf of “corrupt expenditure of N292 million” which he allegedly spent on health care training “without recourse to any appropriate approving authority.”
The NHIS chief has denied any wrongdoing.
On Wednesday, the House of Representatives asked the health minister to recall Mr. Yusuf.
Mr. Adewole had ordered the suspension to allow for unhindered investigation of the corruption allegations.
On Thursday, a civic group criticised the House of Reps for calling for the recall of the suspended official until the ordered investigation was concluded.
