What provider identifier should I use to include in the “Create an Estimate of Out of Pocket Costs” request?

Provider identifier supported in the Care Cost Estimator API is national provider identifier (NPI). You should include id, idType and organizationName in the request.

You will need to enroll in the Change Healthcare’s Clearinghouse — your Change Healthcare representative will work with you to get enrolled. Once you are enrolled, the Care Cost Estimator API can send eligibility and benefit inquiry transaction with your provider identifier and patient’s insurance information to get patient’s eligibility and benefit details for out-of-pocket cost estimate.

A sample provider information in the request body:

"provider": {
            "id": "Z3248882383",
            "idType": "Npi",
            "organizationName": "St. Agnes Hospital"
