Noridian Healthcare Solutions says that Medicare Administrative Contractors (MACs) are having issues with the new flu vaccine code 90674, which is not yet in the Common Working File (CWF).

The main issue with code 90674 is that it requires an update to the CWF, which is not currently scheduled until January 2017 for Part B claims and February 2017 for Part A claims.

Noridian says that it is starting to field more questions since some direction has been provided and that contractors may use a Not Otherwise Classified (NOC) code. However, MACs are having a hard time finding the most appropriate code due to system issues and appropriate definitions.

There are discussions going on between the different MACs and CMS to see if the system can be updated sooner to accept 90674, but as of today there is no resolution. Noridian is suggesting that providers check for the latest information.
