I am receiving rejections for my BCBKS biling with the following error message:
Acknowledgement / Rejected for relational field in error. (A8) Rendering Provider's National Provider Identifier (NPI). Billing Provider's National Provider Identifier (NPI). Rendering Provider's id number. (562)
I have reviewed the related posts to this topic and none of those solutions seems to work. I cannot identify the solution, please advise. Thank you!
