The 24-year-old trained with the Millers on Thursday morning ahead of completing his deal, which will keep him in South Yorkshire until January.
Ipswich boss Mick McCarthy has allowed Hyam to join their Championship rivals in a bid to get game time as he steps up his comeback from knee surgery in the summer, with the injury keeping him out since January.
"I spoke to my
agent and the Ipswich manager Mick McCarthy and they told me that Rotherham
were interested in taking me on loan,” Hyam said.
“They asked me what I
thought and I was keen to come straight away. I always look forward to a
challenge. I’ve never moved previously. I’ve always played at Ipswich all my
career but I just need to play some games now so this is a great opportunity.
“It has been a while
since I have had the opportunity to play first-team football, so this is a
great opportunity for me to get some games and try to impress and help get some
points for Rotherham,” he added.
“I am a hard working
player and I like to get stuck in. I know the club is close to the bottom but I
like to roll my sleeves up and get stuck into the challenge. I like to get up
and down the pitch and hopefully I can do that here and do a good job for the
team.

Hyam, a product of Ipswich's youth academy, will go straight into the Millers squad for Saturday's vital clash with Bristol City and joins Harry Toffolo, Brandon Barker, Leon Best and Stephen Hunt as Redfearn's new signings.
With Lee Frecklington back to fitness and Richie Smallwood back to from, do the Millers need a new midfielder?
