Common pattern needed for Diagnostic Imaging data elements
Diagnostic Studies/Exams should not be a Data Class. This conceptually is the "test" for the Diagnostic Imaging Data Class. See other comments made for Diagnostic Imaging Data Class.

Comment on Laboratory Data (CCD–FHIR Project & Sequoia& Oracle )
Currently, the lack of clear guidance makes laboratory result matching imprecise and reconciliation a laborious process. Catalog maintenance is an ongoing burden. There is no consistent guidance on laboratory orderables & specimens and other parameters —including biomarkers—and their associated results. Keeping orderable/result mapping catalogs synchronized between LIS, EHRs, and device/manufacturer reference data is highly resource-intensive.
Publicly sharing LIS and manufacturer instrument catalogs—including the preferred LOINC and SNOMED CT code values—would be beneficial for providers, potentially reducing duplicate test orders, lowering interpretation errors, and speeding alignment. However, most catalogs remain proprietary. Complicating matters further, a single orderable can trigger additional reflex tests or downstream orderables, without any supporting workflow guides. In addition, LIS systems lack federal support for maintaining and exchanging catalog formats.
It is essential to enable LIS vendors, manufacturers, and providers to publish and share their coded catalogs in a standardized way. This would help EHR systems interpret the vast LOINC vocabulary, recognizing that not all codes are used in practice. Developing standard code value sets—potentially at state and federal levels—would further improve consistency and interoperability.
Recommendation: ONC should work with HL7, Sequoia Project, LIS vendors, manufacturers, and providers and EHRs to establish guidance and infrastructure for sharing laboratory orderable and result catalogs, including standardized value sets for LOINC and SNOMED CT, to support more accurate laboratory result matching and reconciliation under USCDI.
