CARIN BB created CodeSystem resource stubs for external code systems that have URLs, descriptions, and licensing information identified by HTA. Many of these CodeSystem resources have since been added to THO, making the ones in CARIN BB Duplicative. Remove the unnecessary CodeSystem resources incorporated in the IG and update the references accordingly (e.g. in ValueSet resources and any narrative text) for the following IG defined CodeSystems:

• ADAAreaOfOralCavitySystem
• ADADentalProcedureCode
• HCPCSReleaseCodeSets
• CMSPlaceofServiceCodes
• CMSRemittanceAdviceRemarkCodes
• NCPDPBrandGenericIndicator
• NCPDPCompoundCode
• NCPDPDispensedAsWrittenOrProductSelectionCode
• NCPDPPrescriptionOriginCode
• THREEMAPDRG
• THREEMAPRDRG

And the following after Post 3.1.0 release of THO

• ADAUniversalNumberingSystem
• AHANUBCPatientDischargeStatus
• AHANUBCPointOfOriginForAdmissionOrVisitNewborn
• AHANUBCPointOfOriginForAdmissionOrVisitNonnewborn
