Attachments API

A: Attachments submissions take 2 forms: solicited and unsolicited. As an example of an unsolicited attachment, consider workers’ compensation claims. Attachments illustrating the conditions giving rise to the claim are required in all workers’ compensation claims, hence they are called unsolicited claims. Solicited claims usually are sent by payers to providers requesting documentation for a claim.

A: Yes, you can use our sandbox environment to test our API responses before signing a contract. The sandbox will populate canned responses and will not be able to access production-level data. You can request sandbox credentials from your Optum representative or by accessing the request form here. The sandbox is free to use once credentials are obtained. For more information on sandbox responses, please follow this link and visit the Developer’s Portal.

A: The 275 supports each document of up to 64 MB. However, through the API, we allow up to 100 MB.

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

A: Most of our APIs are private and require credentials to gain access. Begin by obtaining your client_id and client_secret for our sandbox test environment. Contact your Optum representative if you do not have this information.
