Former world number one Lee is currently serving a Badminton World Federation (BWF) suspension after testing positive for banned substance dexamethasone at the World Championships in Denmark last August.
He appeared in front of a BWF tribunal in Amsterdam 10 days ago and will have to wait for another two weeks before finding out of the hearing's findings.
Lee has been training under Tey Seu Bock since 2010 with Hendrawan and former singles chief coach Rashid Sidek assisting him.
However, Badminton Association of Malaysia (BAM) technical director Morten Frost Hansen revealed on Monday that some changes have been made in the coaching department.
"It's very important to continue improving things and Chong Wei has had the same coach for a very long time. It is about time to see whether this change can add on a little bit extra possibilities to win the world championship or even the Olympics later on," Hansen told reporters at the BAM office on Monday.
Frost added that Chong Wei Feng will bow be coached by Seu Bock.
Apart from his mentorship of Lee, the 42-year-old Hendrawan will also oversee the coaching of three other players – Liew Darren, Iskandar Zulkarnain Zainuddin and Cheam June Wei.
Hansen also revealed his growing concern of the fitness levels of the country's shuttlers, following last week's two-day trial, and that all national players will be required to undergo fitness training at the National Sports Institute (NSI).
"I would like to see the overall fitness level of our players. I want to test them in NSI and will conduct tests in two groups, one on Friday, April 24, and another group on Thursday, April 30," Hansen added.
