    I have a directory on a remote server that I do get returned a true if I test-path.

    Test-Path "D:\DFSRoot1\Home\HXXXXXX\$SamAcct"

    So I would expect this to work
    Invoke-Command -ComputerName idn-comp -ScriptBlock {Move-Item -Path D:\DFSRoot1\Profile\Hoffman\$($SamAcct) -Destination D:\DFSRoot1\Profile}

    But I always get this result.

    Source and destination path must be different.
    + CategoryInfo : WriteError: (D:\DFSRoot1\Home\HXXXXXX\:DirectoryInfo) [Move-Item], IOException
    + FullyQualifiedErrorId : MoveDirectoryItemIOError,Microsoft.PowerShell.Commands.MoveItemCommand

    My thought are that the variable is being expanded on the remote machine that does not know the value of $SamAcct. So, how do I expand before it's run on remote server?
    I'm running this through a loop, so the directory name is always being held in a variable.

    Either way I always get that error. Any thoughts?

    Are you using PowerShell 3? If so, you should be able to simply prefix your variable with using:, like this:
    Invoke-Command -ComputerName idn-comp -ScriptBlock {Move-Item -Path D:\DFSRoot1\Profile\Hoffman\$($using:SamAcct) -Destination D]
    If you're not using PowerShell 3, then you can pass in arguments using the -ArgumentList parameter of Invoke-Command, and then reference those arguments inside the script block, either as named arguments if you use a param statement or as unnamed arguments by using $args[0], $args[1], and so on.
