You can use the -G option to usermod to specify a comma separated list of secondary groups you want the user to be a member of - i.e. include all their previous secondary group memberships excluding the group you want to remove them from.
I always just vi /etc/group directly. Far easier than specifying a list of secondary groups to usermod.
Cheers,
