Hello~ I'm looking for a CPT for influenza virus vaccine CPT. We are using Fluzone by Sanofi Pasteur. Administration is IM and this vaccine does have preservatives in it. I thought that this should be 90658 but I recevied a denial from the carrier saying the NDC does not match. I've checked the NDC several times to make sure that we submitted it correctly. I would appreciate any feedback if I'm coding incorrectly.
