| 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) | |
| 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.use | |
| 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) | Condition.recorder is also an option. Neither of these fields can repeat like DG1-16 can. |
| 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[1].uri) | |
| DG1-22 (Parent Diagnosis) | is equivalent to | diagnosis.condition(Condition.extension[1].valueReference(Condition)) | Extensions for occurredFollowing and related also exist |
