DiagnosticReport Profile

Canonical	../StructureDefinition/nexus-emr-core-diagnosticreport
Status	draft · 1.26.0
Base	DiagnosticReport (constraint)
Source	FSH · JSON

Defines the Nexus EMR FHIR profile for DiagnosticReport resources, based on CA-Core constraints, for aggregating diagnostic reports (e.g., Lab, Imaging) from multiple EMRs.

Salient fields

The profile's synthesized-accessor contract: fields TypedFhir surfaces as first-class typed properties, each computed from the instance by a restricted FHIRPath expression. See Salient Fields for what they are, how they shape LLM contexts, and how to declare them.

code

Short	Diagnostic report type with raw code support
Definition	Type of diagnostic report (e.g., CBC, Chest X-ray, Lipid Panel). REQUIRED: text element for human readability RECOMMENDED: LOINC or other standard terminology when available OPTIONAL: Raw EMR codes for source system preservation Nexus EMR does not mandate a specific coding system for diagnostic report types. The text element ensures human readability even when coded values are not recognized.
Comments	Where this code was mapped from a source system's own vocabulary, carry the raw coding alongside the mapped one, flagged userSelected = true. See Carrying the raw code.
Expression	code
Type	coded

status

Short	Where the report is in its lifecycle
Definition	The status of the diagnostic report. Indicates whether the report is complete and verified.
Comments	This is a modifier element. Preliminary reports should be interpreted with caution.
Expression	status
Type	code
Prose inherited from	DiagnosticReport.status

category

Short	Service category with raw code support
Definition	Classification of the clinical discipline, department or diagnostic service that created the report. RECOMMENDED: Standard terminology codes (e.g., HL7 Diagnostic Service Section Codes) OPTIONAL: Raw EMR codes for source system preservation Multiple categories may be specified to classify the report in different ways.
Comments	Multiple categories are allowed using various categorization schemes. The level of granularity is defined by the category concepts in the value set. More fine-grained filtering can be performed using the metadata and/or terminology hierarchy in DiagnosticReport.code.
Expression	category
Type	coded
Prose inherited from	DiagnosticReport.category

effective

Short	Clinically relevant time/time-period for report
Definition	The time or time-period the observed values are related to. This is usually the time specimen was collected or imaging was performed.
Comments	For lab reports, this is typically when specimen was collected. For imaging, when the images were taken.
Expression	effectiveDateTime | effectivePeriod.start
Type	dateTime
Prose inherited from	DiagnosticReport.effective[x]

issued

Short	DateTime report was released
Definition	The date and time that this version of the report was made available to providers.
Comments	May be different from the effective date, especially for amended reports.
Expression	issued
Type	dateTime
Prose inherited from	DiagnosticReport.issued

conclusion

Short	Clinical conclusion (interpretation) of test results
Definition	Concise and clinically contextualized summary conclusion of the diagnostic report.
Comments	The narrative conclusion shall only contain filtered information from the report.
Expression	conclusion
Type	string
Prose inherited from	DiagnosticReport.conclusion

data

Short	Data inline, base64 encoded
Definition	The actual data of the attachment - a sequence of bytes, base64 encoded.
Comments	The base64-encoded data SHALL be expressed in the same character set as the base resource XML or JSON.
Expression	presentedForm.first().data
Type	base64Binary
