Alternatively, you may use the search page to upload an electronic remittance (X12 835) file that you have obtained from your payer or clearinghouse. You can do this by clicking the Browse button and selecting the file to upload, and then clicking Search to perform the upload and display the corresponding invoices. In this case the other parameters mentioned above do not apply and will be ignored. Uploading saves the file but does not yet process its contents -- that is done separately as described below.
