NOT allow electronic claims to still get electronically filed if the attachments are rejected.
It would be easier and less confusing for everyone, that when attachments to electronic claims get rejected, that the claim would also not get sent at all. That way the claim could be sent only once, by other means with all the extra information required. There are several insurance companies that REQUIRE the additional information that is being sent in these attachments, and we can't look up every single company before sending every claim everyday, to check if it accepts attachments. Especially, since the program already automatically REJECTS the attachments to those companies. If the attachment is rejected, so should the claim it was attached to, as well as pop up a warning (just like it already does with rejected attachments) stating to submit the claim by another method.
We already have the ability to send attachments alone, using the reference number for a claim, this way if your attachment is denied, you can resend just the attachment.
