Carequality identity and organization structure

Last updated: Nov 7, 2025

IMPLEMENTATION

The Carequality Interoperability Framework uses object identifiers (OIDs) to designate unique organizations and records belonging to Carequality participants. An OID is a globally unique identifier defined by the International Organization for Standardization (ISO). Learn more about OIDs.

Key takeaways

Carequality uses object Identifiers (OIDs) to uniquely identify organizations and records.
Redox provides three OID types for you: organization, patient, and document.
Your organization is part of the main Redox gateway OID.
You might need to create multiple child organizations (using the partOf field) if you have multiple MPIs or physical locations.

Carequality OIDs

You must use (and we provide for you) three OID types within the Carequality:

OID type	Description	OID structure
Organization	Corresponds to your organization on Carequality.	2.16.840.1.113883.3.6147.458.xxxxx.x.x.1.1
Patient	Corresponds one-to-one with your Master Patient Indexes (MPIs). We create the first one for you, but if you have multiple MPIs, you should create a patient OID for each MPI in your system.	2.16.840.1.113883.3.6147.458.xxxxx.x.x.2.1
Document	Corresponds one-to-one with each document you exchange over Carequality. Each document must have its own unique OID, which can either be a Redox-generated OID followed by your ID (e.g., …3.1^12345) or a version 4 UUID. Learn more about version 4 UUIDs.	2.16.840.1.113883.3.6147.458.xxxxx.x.x.3.1

If you believe you need additional OIDs, talk to a Redoxer for options and pricing.

Your organization OID

If you’re using Network Onramps, your organization is part of the Redox gateway OID, which is typically based on this OID: 2.16.840.1.113883.3.6147.458.2.

Using an existing OID

Network Onramps pricing requires that you use an OID that we provide. If you would rather use an existing OID, talk to a Redoxer to discuss your needs and get more information about pricing.

If you’re responding to Carequality on your own—or if you have a valid exception to mutual exchange—your OID is different: 2.16.840.1.113883.3.6147.458.3.

Multiple Carequality organizations

There should be a one-to-one relationship between a parent organization and each patient census setup. The parent organization record should point to the Redox gateway: 2.16.840.1.113883.3.6147.458.2.

You might need to create multiple organization records under one parent organization if you meet one of the following criteria:

You have multiple brick-and-mortar locations where you provide services to patients.
You work with multiple MPIs. For example, you provide services on behalf of a provider who has their own MPI.
You want to list your organization in multiple locations to make your patients more discoverable to other Carequality participants.

We recommend defining a hierarchy for your organization by using the partOf field in Organization.New data model to create child organizations.
