#### Cross Version Analysis

This is an R4 IG. None of the features it uses are changed in R4B, so it can be used as is with R4B systems. Packages for both R4 (ihe.iti.pixm.r4) and R4B (ihe.iti.pixm.r4b) are available.

HL7 Terminology (THO) | hl7.terminology.r4#7.0.1 | R4 | Automatically added as a dependency - all IGs depend on HL7 Terminology
FHIR Extensions Pack | hl7.fhir.uv.extensions.r4#5.2.0 | R4 |
Basic Audit Log Patterns (BALP) | ihe.iti.balp#1.1.4 | R4 |
HL7 Terminology (THO) | hl7.terminology.r4#6.5.0 | R4 |

FHIR Tooling Extensions IG | hl7.fhir.uv.tools.r4#0.9.0 | R4 | for example references

Package hl7.fhir.uv.extensions.r4#5.2.0 This IG defines the global extensions - the ones defined for everyone. These extensions are always in scope wherever FHIR is being used (built Mon, Feb 10, 2025 21:45+1100+11:00)

Package ihe.iti.balp#1.1.4 The Basic Audit Log Patterns (BALP) Implementation Guide is a Content Profile that defines some basic and reusable AuditEvent patterns. This includes basic audit log profiles for FHIR RESTful operations to be used when there is not a more specific audit event defined. A focus is enabling Privacy centric AuditEvent logs that hold well formed indication of the Patient when they are the subject of the activity being recorded in the log. Where a more specific audit event can be defined it should be derived off of these basic patterns. (built Fri, Oct 31, 2025 12:53-0500-05:00)

Package ihe.iti.pdqm#3.2.0 The Patient Demographics Query for Mobile (PDQm) Profile defines a lightweight RESTful interface to a patient demographics supplier leveraging technologies readily available to mobile applications and lightweight browser based applications. (built Tue, Nov 4, 2025 12:07-0600-06:00)

Package hl7.fhir.uv.tools.r4#0.9.0 This IG defines the extensions that the tools use internally. Some of these extensions are content that are being evaluated for elevation into the main spec, and others are tooling concerns (built Tue, Dec 16, 2025 23:18+1100+11:00)
