What payers are available for sending attachments electronically?

And for payer connection details, see [npd](https://customerconnect.optum.com/payerlist) or [cap](https://customerconnect.optum.com/payerlist) .

Do I have to use PayerID values or can I use CPID values to send the claim?

Submitters can use either value.

What types of file formats are supported?

File formats supported by Batch medical attachments

Our Attachments Submission API supports the following formats for 275 attachments: JPG, TIF, TIFF, PDF, JPEG, and PNG. Payers provide varying support for these formats. Consult your Optum representative to determine which formats your payers can work with.

Our Attachments solution includes workers’ compensation attachments and medical attachments. Any receiver who does not support electronic attachments will receive the documentation through fax or mail.

File types supported

This API enables you to obtain files of the following types:

• EDI 277 Claim Status report files — responses to EDI 276 Claim Status inquiries, that you can send using our Claim Status APIs;

  Institutional (837i) Claim electronic submissions, and for paper and electronic CMS 1500 and

Are there file size limitations?

275 supports each document of up to 64 MB. But through the API, we allow up to 100 MB.

Can I send more than one document?

How are the claim and the attachments linked together?

Do you try to match the claim and attachments?
