Okay I got in contact with my rep and this is what has happened.

There is a system issue that was identified for VFC vaccines. Per the claims department, VFC claims are denying incorrectly. The system has been updated and the claims department has submitted a project to CPM to capture all claims impacted.

This issue will be tracked under Issue or MID #1204759, I will provide updates as I receive them. This impacted the entire state of Missouri so it may take up to 30 days for the claims project to be completed. Thank you!
