r4/relatedperson and Authorized Representative

Jean MinnaarOct 3 2025 — edited Oct 3 2025

We need to find out who a given person has jurisdiction over. And then too, who has jurisdiction over a given person. (Both directions.)

From what I can tell, I am to use the Related Person's ‘Get a related person record by ID’. Is this the right API?

Assuming it is…

In calling this endpoint passing in the person ID of a “parent”, the relationship collection looks as follows:

In calling the endpoint for one of the “children”, the same section looks as follows:

A screenshot of a computer program<br />AI-generated content may be incorrect.

It looks like one can use the relationship collection to determine the “direction” of authority. If the person the inquiry runs for is a “child”, you will see two (maybe more?) relationship entries and one of them will be coded as “Authorized Representative”. And if we run the query for a “parent”, you will see one relationship entry and it would not be an “Authorized Representative” entry. Correct?

But two spouses can have authority over each other as well as their kids. What would the entries look like in those cases?

Please provide instructions how to go about determining the “parent/child” and "child/parent" relationships. Not just who is whose child and who is a person's parents, but who has jurisdiction over who.

I used “parent” and “child” for simplicity sake only.
