The US Core Implementation Guide defines the minimum set of FHIR RESTful interactions for each of the US Core Profiles to access patient data. The Data Access Framework and the Argonaut DSTU2 guides initially formed the basis for US Core. The Profiles are updated annually to support the latest requirements from ASTP U.S. Core Data for Interoperability (USCDI). For a summary of significant changes and a detailed list of the changes between versions, see the Change Notes at https://hl7.org/fhir/us/core/changes.html
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 (hl7.fhir.us.core.r4) and R4B (hl7.fhir.us.core.r4b) are available.
IG Dependencies
This IG Contains the following dependencies on other IGs.
Package hl7.fhir.uv.extensions.r4#5.2.0

- Using RxNorm codes of type SAB=RXNORM as this specification describes does not require a UMLS license. Access to the full set of RxNorm definitions, and/or additional use of other RxNorm structures and information requires a UMLS license. The use of RxNorm in this specification is pursuant to HL7's status as a licensee of the NLM UMLS. HL7's license does not convey the right to use RxNorm to any users of this specification; implementers must acquire a license to use RxNorm in their own right.
