This endpoint is in beta and is subject to change.

This endpoint submits a 275 claim attachment to a payer and returns summary information about the attachment submission. Before you can submit an attachment through this endpoint, you must:

This endpoint is for 837 claims submitted in JSON format. If your system already generates X12 EDI, you can send attachments through the Submit Claim Attachment (275) Raw X12 endpoint instead.

This endpoint only supports unsolicited attachments.

You must supply the following information in your request to link the attachment to the correct 837 professional, dental, or institutional claim:

PropertyDescription
relatedTransactionId or relatedExecutionIdAn identifier for the 837 claim you previously submitted through Stedi. This value tells Stedi which claim is related to the attachment.
attachmentIdThe attachment ID you received in the Create Claim Attachment (275) JSON response. This value tells Stedi which file to use when generating the 275 transaction for the payer.
providerAttachmentControlNumberThe value you set in the claim’s attachmentControlNumber property. It allows the payer to associate the attachment with the claim that’s already in their system.
providerControlNumberThe value you set in the claim’s providerControlNumber property. This property is optional and allows you to indicate that the attachment should be associated with only a specific service line from the claim. This doesn’t apply to dental claims.
