**Context of Use**

### Profile Specific Implementation Guidance

This section provides detailed implementation guidance for the US Core Profile to support implementation and certification.

* The recommended codes for tribal affiliation are the [TribalEntityUS](https://terminology.hl7.org/5.5.0/ValueSet-v3-TribalEntityUS.html) values. However, the Indian Health Service [Standard Code Book](https://www.ihs.gov/scb/standard-code-book-tables/tribe/) is an alternative set of codes for specific reporting purposes.
* `isEnrolled` is an optional sub-extension for systems that choose to collect this information

**Usage info**
