Application Programming Interface (API)

A new way to automate your data feeds. API is designed to help your organization improve efficiency, reduce costs and increase cash flow.

API is an emerging digital method in health care to distribute information from payers. Our API solutions allow you to electronically receive detailed data on member eligibility, claims status, payments, appeals and paper correspondence. Data can be transferred directly to your practice management, hospital information system or any application you prefer. Introduction to API

How to get started

API requires technical coordination with a health care professional or business partner’s IT department, vendor or clearinghouse. During the initial consultation, we review compatibility and API connectivity options and transaction types.

When you’re ready to implement API, we provide direct onboarding and support in coordination with the Optum technical team. Once in production, we monitor API usage compared to call volumes to identify opportunities to further reduce incoming calls.  Use the button below to request a consultation, include your name, title, organization name, email address and phone number. 

As a client, you can use API to exchange information from your database to UnitedHealthcare’s database and vice-versa, we then use this data to help you complete clinical activities and to improve how you work with us.

Why add API to your practice?

API is designed to help reduce phone calls and paper handling, while contributing to a smoother workflow. Automatic data feeds are created to pull information on a timetable you set, and transfer the data to your practice management system, proprietary software, portal, spreadsheets or any application you prefer. 


  • Used by practices, facilities, health care systems, vendors, clearinghouses and revenue cycle management companies
  • Various levels of data are accessible for each API type. Choose those that that fit the needs of your organization.
  • APIs are available for many UnitedHealthcare payers and plans. Payer IDs are indicated on each API Guide.


  • Fill in gaps for information you may not be getting in your current data streams, such as electronic data interchange (EDI)
  • Share and distribute data throughout your practice more easily and efficiently
  • Streamline daily workflows and reduce staff time spent on manually retrieving information from the UnitedHealthcare Provider Portal
