Can anyone please assist with this? We billed these vaccines recently for some pediatric patients, dtap 90700, hep A 90633 & hep b 90744. They were age appropriate however the insurance did not cover them. The insurance remark showed, covered preventative services are limited to services required the the patient protection and affordable care act. I have read articles on the PPACA and I am still confused. This is the first time I am seeing this denial code. Also, can the patient be billed?
