We use Patagonia. We sent out our very first batch of COVID 19 HRSA uninsured patients to be billed. Half were rejected, half were accepted, with no discernable difference between one that’s accepted and one that’s rejected.
When you look at the claim rejection details, it states “21 – Missing or invalid information. Note: At least one other status code is required to identify the missing or invalid information.”
Any information would be greatly appreciated
