The Trusted Exchange Framework and Common Agreement (TEFCA) uses object identifiers (OIDs) to designate unique organizations and records belonging to network participants. An OID is a globally unique identifier of the International Organization for Standardization (ISO). Learn more about OIDs.

TEFCA OIDs

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

OID type
Description
OID structure
Organization
Corresponds to your organization within TEFCA.
2.16.840.1.113883.3.6147.450..1.X.XXXX.X.X.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 as many patient OIDs to equal the number of MPIs in our system.
2.16.840.1.113883.3.6147.450..1.X.XXXX.X.X.2
Document
Corresponds one-to-one with each document exchanged. You must have a document OID for every document you exchange. This can be either Redox-generated OID followed by your ID (e.g., …3.1^12345) or a version 4 UUID. Learn more about version 4 UUIDs.
2.16.840.1.113883.3.6147.450..1.X.XXXX.X.X.3
