IMPORTANT

The sandbox returns a canned response based on the received data. There is no validation check or confirmation of specifically required information. These checks would only occur in the production environment. You would need to manually review the companion guides offered by the specific payers to confirm what is required for each.

Explore how the JSON-to-EDI mapping works.

After you have tested and selected the product for your business type, you are ready for transiting to production environment.

🔴 Attachment Submissions
The Attachment Submissions v1 API allows clients to submit claim attachments and query their status. Attachment submissions take two forms: Solicited and Unsolicited. Solicited claims usually are sent by payers to providers requesting documentation for a claim. The API supports the X12 EDI 275 Patient Information transaction. It translates this standard to JSON, so it is more accessible to developers for integration into users’ applications.

🔵 Claims Status
The claim submitter uses a Claim Status v2 API request to inquire about the status of a previously submitted claim. If the claim is finalized, the response provides the disposition of the claim (for example, Paid, or Denied). For Denied or Rejected outcomes, the response includes the reasons for the denial or rejection. The payer returns the response, as an X12 EDI 277 transaction, which is translated back to JSON by the API gateway. It translates this standard to JSON for developer accessibility and integration into users’ applications.

🔶 Eligibility
The Eligibility v3 API provides complete patient profile and benefits information to support healthcare delivery and more-efficient and accurate reimbursement. Providers get better front-end information to improve claiming processes and reimbursement rates. For payers, claims spend less time in pending status and a fewer rejected and reworked claims. It makes this popular EDI transaction set more accessible to developers and users’ applications. The API uses the standard X12 EDI 270 eligibility transaction, and formats it in JSON for an HTTP request. We manage the X12 standards in the background, and give you efficient access to medical subscriber or dependent plan membership, copays, coinsurances, deductibles, and more in an easy-to-use, human-readable format.
