"comment": "While the IPS-UV specification considers this a Must Support element, some systems will not have a field directly representing clinicalStatus, but have other means of differentiating between current and historical conditions. Implementers are expected to be able to differentiate between active and inactive conditions. However, the valueSet that is required in the base specification does not provide an 'unknown' concept to support legacy data without a clinicalStatus. This has resulted in additional burdens that some participating systems could not meet with their legacy data.\n\n The requirement from the base FHIR specification to provide a system and value from the bound value set means the PS-CA CodeableConcept data type profile does not need to be applied on this particular element.\n\nIn the scope of the IPS-UV the entered-in-error concept is not allowed and so the modifier on this element has been removed.",

The Condition - IPS ValueSet contains codes that are subsumed within the SNOMED CT CA ClinicalFindingCode ValueSet that is preferred for this element.\n\nFuture releases of PS-CA may require use of coded entries. In this release, however, implementations that support codings are encouraged to send the codings for codeable concepts if they are available. Consistent with FHIR best practice, receivers should not produce failures or rejections if codings are received. Vendors should expect that some jurisdictions may further constrain support of this element within the context of their own jurisdictional content.",
