The world silver medallist, 33, has not competed since June and has skipped several events in a patchy season, with his withdrawal from a Team GB training camp in Portugal the last straw for authorities, who have asked for evidence about his recent injuries.
All BOA team members signed to an agreement that allows them to ask for information from an athlete that "could impact on their performance at the Games", but Idowu is unhappy that this was made public, appearing to question his commitment or honesty.
"He's incredibly disappointed and surprised as to why the BOA has chosen to do this," Idowu's agent Jonathan Marks said.
"I can't understand the benefit to the athlete."
BOA spokesman Darryl Seibel said on Tuesday that they had yet to receive that information, although it has since been reported that Idowu has submitted the details.
"Yesterday our chief medical officer Dr Ian McCurdie wrote to Phillips and also to his agent and asked him to provide, on a strictly confidential basis, any medical information relating to his injury and ongoing treatment," Seibel said.
"The purpose is to add clarity to the picture and understand the exact nature of the injury and the ongoing treatment for it.
"As you and I speak now we have not received that."
Idowu is still set to compete at the Games on August 7 and is among the gold medal favourites having claimed silver in Beijing four years ago.
The 33-year-old pulled out of his last event in Oregon in June but said stories suggesting he was injured were "rumour mill".
He is likely to be someway short of peak condition should he recover in time for the Games having competed in only three competitions this year.
The last time he was in action was several weeks ago in early June, when he injured his foot at the IAAF Diamond League in Eugene, although he did run with the Olympic torch on Saturday.
He missed the Olympic trials but later claimed that was as a 'precaution' rather than because he was injured, as suggested by UK Athletics head coach Charles van Commenee.
Then he pulled out of the recent Aviva Grand Prix just a few minutes before competition after suffering from tightness in his left hip during his warm-up.
"In training recently Phillips has had an ongoing injury problem and we have not been able to go at things 100 per cent," said Idowu's coach Aston Moore.
“At the weekend, Phillips told me he would continue to seek treatment from a private physio in London and would not travel to prepare in Portugal, although he may join us here later.
“He is an experienced athlete who I have worked with for more than four years and we will assess the situation again in the coming days."
