PCT AEOB Composition that assembles the contents of an AEOB (represented by one or more individual AEOB resources) into a single logical package. A Composition for the document type Bundle that enables versioning, signing and being referenced by a DocumentReference for searching and subscription notifications. 

### Example Usage

This profile does not include directly linked examples (available in an "Examples" tab at the top of this page) because the profile requires that referenced resources be included in the same bundle in which they exist.

As such, the example of this profile is included in [Advanced Explanation of Benefit Packet example](Bundle-PCT-AEOB-Packet-1.md)

**Usages:**

* Use this Profile: [PCT AEOB Packet](StructureDefinition-davinci-pct-aeob-packet.md)

You can also check for [usages in the FHIR IG Statistics](https://packages2.fhir.org/xig/hl7.fhir.us.davinci-pct|current/StructureDefinition/davinci-pct-aeob-composition)
