.prop will do it.

$("#select_test").append($("<option>").val(hogeCd).text(hogeName).prop("selected", true));

Below is a sample.

$(function(){
  $("#select_test").append($("<option>").val("1").text("value 1"));
  $("#select_test").append($("<option>").val("2").text("value 2").prop("selected", true));
  $("#select_test").append($("<option>").val("3").text("value 3"));
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<select id="select_test">
<option value="">Please select</option>
</select>
</form>
