web	github.com	MADiE uses the open-source cqframework CQL-to-ELM Translator to translate CQL into Expression Logical Model (ELM), the computable representation used for validation and execution of CQL expressions.
web	github.com	Create an issue in the CMS QMD IG repository . Include a brief description of the change as well as relevant details such as standards versions, applicable timelines or related ONC Jira issues.
web	github.com	For both NutritionOrder and ImmunizationRecommendation, the translator does not allow qualified code paths to be used in the retrieve (see the feature request #1853 ). Until that is implemented, use a where clause rather than a terminology-based retrieve:
web	github.com	NOTE: ClaimCommon and ClaimElements are released in MADiE, so measures can include them directly. Development happens in the dqm-content-cms-2026 repository, and the copies in this guide are convenience copies. The intent is to promote ClaimElements to the Using CQL with FHIR implementation guide, generalized to all claims: its retrieves would become [FHIR.Claim] rather than [USQualityCore.Claim] . Nothing in the logic depends on the US Quality Core profile.
web	github.com	This is under review and may result in a specification or tooling change (see Translator Issue 1181 ). Until then there are two workarounds:
web	github.com	For comparison, see the QICore Version
web	github.com	NOTE: MedicationCommon is released in MADiE, so measures can include it directly. Development happens in the dqm-content-cms-2026 repository, and the copy in this guide is a convenience copy. Nothing in it is US-specific, so the intent is to promote the library as a whole to the Using CQL with FHIR implementation guide ( FHIR-58912 ), alongside FHIRCommon, as the home for medication-specific functions.
web	github.com	Feedback on the patterns, guidance, or recommendations can be provided by submitting a New Issue to this repository.
web	github.com	The remaining libraries are expected to still be developed in MADiE, but are included in the proposed set of refactored measures for reference, testing, and to support the development of this guidance. A third group — ClaimCommon, ClaimElements, and MedicationCommon — supplies functions that no published library provides yet. These are released in MADiE and developed in the dqm-content-cms-2026 repository, with convenience copies in this guide, and are proposed for promotion to the Using CQL with FHIR implementation guide. The version numbers of those libraries are suggested based on both a Major and at least one Minor version increment for each library (for example, AdultOutpatientEncounters in QICore is version 4.19.000, whereas the suggested refactoring is 5.2.000). The content for these libraries is suggested, and it is expected that these libraries will be developed in MADiE once full US Quality Core support is available. Measure developers can use the content as a starting point for that development if desired.
web	github.com	The dqm-content-cms-2026 repository has minor increments for each of these libraries as well with the full update to the 0.5.0 published release. Those increments will be pulled into the cms-2025 repository once discrepancy testing has completed.
web	github.com	In addition, the in-madie branch of the dqm-content-cms-2026 repository has the content that is available in MADiE for easy comparison against the proposed draft content.

web	github.com	The QICore-based CQMCommon 4.1.000 is being refactored into CQMConcepts, CQMElements, and CQMInferences (see the note in the Library Index ), with claim-related content moving to ClaimCommon and ClaimElements. Its definitions are distributed as follows:
web	github.com	Every non-extension slice in QI Core STU6 is present at the same element path with the same slice name in US Quality Core 0.5.0. Nothing was added, removed, or renamed at the profile level. The difference is entirely in the model info: the QICore 6.0.0 model info was profile-informed, so it flattened each slice into a named model element , and CQL could write Coverage.memberid or Observation.VSCat directly. In the USQualityCore 0.5.0 and USCore 6.1.0-derived model infos, slices are now accessed through fluent functions . Where no published library supplies one, a function is provided in CQMConcepts , annotated with the library it is being proposed for, and marked as proposed in the tables below.
web	github.com	isScreeningAssessment() (CQMConcepts, proposed for USCoreCommon)
web	github.com	also defined in MedicationCommon , proposed to replace the FHIRCommon definitions
web	github.com	isAssessPlan() (CQMConcepts, proposed for USCoreCommon) , hasCategory(CarePlan, Code) (CQMConcepts, proposed for FHIRCommon)

web	github.com	flowRate() (CQMConcepts, proposed for USCoreCommon)
web	github.com	concentration() (CQMConcepts, proposed for USCoreCommon)
web	github.com	industry() (CQMConcepts, proposed for USCoreCommon)
web	github.com	No hasCategory() overload exists upstream for CarePlan, DiagnosticReport, or ServiceRequest. FHIRCommon defines hasCategory() only for Condition , Observation , and MedicationRequest . The overloads for the other three, and the isLaboratory(DiagnosticReport) predicate, are drafted in CQMConcepts and proposed for FHIRCommon, since none of them is US-specific.
web	github.com	No accessors exist upstream for the identifier slices. Neither USCoreCommon nor USCoreElements provides npi() , clia() , naic() , ccn() , or ein() , so measures that identified a provider or facility by Practitioner.NPI or Organization.ccn under QI Core must filter identifier by system. Those functions are drafted in CQMConcepts ; npi() , clia() , and naic() are proposed for USCoreElements, while ccn() and ein() are proposed for USQualityCoreCommon, because those two slices are QI Core additions rather than US Core content.
