This API uses a comprehensive dataset of eligibility records from multiple health plans to support more accurate and efficient claims processing. It helps determine the correct order of coverage, reducing information gaps that can lead to billing errors, eligibility denials and recovery inefficiencies.
By identifying the correct primary payer before claim submission, the solution helps reduce eligibility errors, alleviate administrative rework associated with claims processing, and minimize unnecessary overpayments and rebilling.
Reduce error driven expenses and streamline claim handling. With fewer reroutes and corrections, payers experience faster processing, improved operational efficiency and more predictable payment cycles.

A: Yes. A try before you buy sandbox is available, allowing developers to explore API behavior, review sample responses, and validate integration steps. Sandbox credentials can be requested through the Developer Portal or an Optum representative here.
A: Developers have access to comprehensive API documentation, including endpoint guides, schema details, sample payloads, and sandbox testing tools. These resources are designed to streamline implementation and accelerate time to value.
A: This API is designed specifically for payers in health care. Real-time COB API supports payer workflows such as primary payer determination and pre‑payment coordination of benefits validation. Providers should refer to Optum Real solutions for provider‑focused coordination‑of‑benefits needs.
A: Health plans, third‑party administrators, and payer‑focused health technology platforms benefit most—particularly organizations seeking to reduce eligibility‑related denials, improve claim accuracy, or automate COB validation within existing workflows.
The API queries eligibility and coverage data across multiple health plans to confirm the correct order of coverage. This automated approach helps close information gaps that commonly lead to denials and downstream claim corrections.
A: Yes. A sandbox environment is available to test API responses before signing a contract. The sandbox provides canned responses and cannot access production‑level data. Sandbox credentials can be requested through your Optum representative or via the Developer Portal.
