Why did the insurance company bundle the immunization with the physical?

I recently received a remit back from BCBS and they didn't pay for the physical.
This is the claim that I billed:
99385 with diagnosis V70.0,
90471 with diagnosis V06.1,
90715 with diagnosis V06.1,
36415 with diagnosis 272.0,
99202 with modifier -25 with diagnosis 272.0 and 600.00.
The remit I received back paid for everything but the physical code which was the 99385. The remark code I received was N19 for procedure code incidental to primary procedure. When I called the insurance company which was BCBS they said that the 99385 had been bundled with the 90471 and that the claim had been processed correctly on their end. Is there a different way I could of coded this? I have coded for physicals and E/M visits and have been paid before. The only thing different with this claim is the immunization. Any suggestions on what I should do or do we just eat the amount we billed for the physical?

I would try a mod 25 on the preventive exam code too. CCI edits are bundling the admin into the visit. American academy of pediatrics has a good article about it and requested CMS/NCCI to get rid of that bundling edit.
