AAOS removed their reference to size in their CodeX in 2010. They are the ones that said 8-10mm of bone must be removed to qualify for 29824, but as of 2011 CodeX that is no longer in their description for this procedure. So...you are correct it used to be that way...and it's still a general good rule of thumb to go by, but no longer can be used by insurances to deny the procedure if less than 8mm is removed.
