Mapping from (not specified) to (not specified)
Group 1 Mapping from unspecified code system to unspecified code system
| Source Code | Relationship | Target Code | Comment |
| DG1-3 (Diagnosis Code) | is equivalent to | diagnosis.condition(Condition.code) | |
| DG1-4 (Diagnosis Description) | is equivalent to | diagnosis.condition(Condition.code.text) | Doesn't warrant mapping |
| DG1-5 (Diagnosis Date/Time) | is equivalent to | diagnosis.condition(Condition.onsetDateTime) | Should confirm that these two concepts are equivalent. Condition.recordedDate is also available |
| DG1-6 (Diagnosis Type) | is equivalent to | diagnosis.role | |
| DG1-15 (Diagnosis Priority) | is equivalent to | diagnosis.rank | Could contribute to Condition.category or be a new extension |
| DG1-16 (Diagnosing Clinician) | is equivalent to | diagnosis.condition(Condition.asserter(Practitioner) | While DG1-16 can repeat, we are not aware of instances where this is used. Until such time, we will not yet establish an agreed to method to communicate the extra repeats in FHIR. |
| DG1-19 (Attestation Date/Time) | is equivalent to | diagnosis.condition(Condition.extension[1].url) | |
| DG1-19 (Attestation Date/Time) | is equivalent to | diagnosis.condition(Condition.extension[1].valueDateTime) | It is unclear whether to use recorded or asserted date. What is your opinion? |
| DG1-19 (Attestation Date/Time) | is equivalent to | diagnosis.condition(Condition.recordedDate) | It is unclear whether to use recorded or asserted date. What is your opinion? |
| DG1-20 (Diagnosis Identifier) | is equivalent to | diagnosis.condition(Condition.identifier) | We should confirm that this is truly a unique ID before it gets used as .id. It may need to be combined with a visit ID to make it fully unique. |
| DG1-21 (Diagnosis Action Code) | is equivalent to | diagnosis.condition(Condition.verificationStatus.coding.code) | Other values (A and U) don't map to anything |
| DG1-21 (Diagnosis Action Code) | is equivalent to | diagnosis.condition(Condition.verificationStatus.coding.system) | |
| DG1-22 (Parent Diagnosis) | is equivalent to | diagnosis.condition(Condition.extension[2].url) | |
| DG1-22 (Parent Diagnosis) | is equivalent to | diagnosis.condition(Condition.extension[2].valueReference(Condition)) | Extensions for occurredFollowing and related also exist |
