when your dx. Ode is the same for the visit as well as the test, the paye does have a tendency to deny the Ua as being a part of the visit. So for one I see no reason for the 25 modifier, then for some payers I find that I do need the 59 on the ua it goes back to an old bundling edit that most payers removed but some still have., also add the code for family history of DM, also since the abnormal result is another symptom I would add in the other symptoms you have documented. Now for the 36415, I see a finger stick documented which would be the 36416 and perhaps that is the reason for that denial, also some consider the collection of the blood an integral part of the lab test and not separately billable. I hope this is of some assistace
