Group 1 Mapping from unspecified code system to unspecified code system
| Source Code | Relationship | Target Code | Comment |
| DG1-3 (Diagnosis Code) | is equivalent to | code[1] | |
| DG1-4 (Diagnosis Description) | is equivalent to | code[1].text | |
| DG1-5 (Diagnosis Date/Time) | is equivalent to | onsetDateTime | Should confirm that these two concepts are equivalent. Condition.recordedDate is also available |
| DG1-16 (Diagnosing Clinician) | is equivalent to | 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 | extension[1].url | |
| DG1-19 (Attestation Date/Time) | is equivalent to | 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 | recordedDate | It is unclear whether to use recorded or asserted date. What is your opinion? |
| DG1-20 (Diagnosis Identifier) | is equivalent to | identifier | |
| DG1-21 (Diagnosis Action Code) | is equivalent to | verificationStatus.coding.code | Other values (A and U) don't map to anything |
| DG1-21 (Diagnosis Action Code) | is equivalent to | verificationStatus.coding.system | |
| DG1-22 (Parent Diagnosis) | is equivalent to | extension[2].url | |
| DG1-22 (Parent Diagnosis) | is equivalent to | extension[2].valueReference(Condition) | Extensions for occurredFollowing and related also exist |
