Specific Insurance returning code error.

I have one insurance panel that is returning this error:

Acknowledgement/Rejected for Invalid Information - The claim/encounter has invalid information as specified in the Status details and has been rejected.
Rendering Provider's specialty/taxonomy code. H52002 Rendering Provider Specialty Code 'Tax id or SSN' not found in Taxonomy Code Table. 

How do I fix this? I am sure that my Tax ID Taxonomy Code are accurate on the claim submissions as I have double checked it multiple times.
