Rejection: Billing NPI IS not authorized for Tax ID

What happened: Billing NPI in box 33a is not linked to the Tax ID sent in box 25 in the payer's system.

Resolution: Need to contact the payer to verify what they have on file for the provider. If that has already been done, please contact our customer service department with documentation that the TaxID and NPI are on file with the payer and a ticket will be opened. Passed/paid claim examples cannot be used as the documentation. Customer Service can be contacted via live chat, email ( and phone (360-975-7000 option 1).
