562 - Entity's National Provider Identifier (NPI). Usage: This code requires use of an Entity Code.

This is a common error from Medicare, but may also come from other payers that follow the same error reporting as Medicare's system.

According to Medicare, the most common reason for this error is one of two things.

1. You are submitting using a billing NPI that is different than the NPI that you have on file for your group (or billing provider).  You can view edit your billing NPI in Therabill by clicking the edit icon next to the billing provider on the right of the error page.  Alternatively, you can edit the billing provider NPI directly from your member information (under Admin).
2. The rendering provider (therapist) NPI is not associated with your billing provider (your group) NPI that you have on file with the payer.  If this is the case, then you will need to call the payer (i.e. Medicare) to get the therapists NPI added to your billing NPI.
