What does IRS code 766 mean on a transcript?

My boyfriend's 2011 tax refund was wittheld to pay a non-IRS debt (child support). The transcript shows code 898 (refund applied to non-IRS debt), but the next line is code 766 (reversal of refund applied to non-IRS debt). We just want to be sure that the refund was applied to child support. Is that what the code 766 means? He never requested a reversal or received any of the refund.
