NDC# denied as invalid for TDAP and Prevnar

In the past month, our practice (primary care) started getting denials from Medicare and Bcbs for TDAP vaccine (NDC 49281-0400-15) and Prevnar vaccine (NDC 00005-1971-02), stating invalid NDC code. We had not changed anything in our system and have verified the numbers on the vaccine box and it is correct. We have researched online and cannot find that anything has changed. Now, we are starting to receive NDC denials from other insurances-UHC, Aetna, etc. I have called several insurance companies and all they tell us is that it is invalid. Help!
