Question on Mapping Cancer data to Observation

If there is a diagnosis of "personal history of malignant neoplasm of breast " with status as “secondary” diagnosis. Can I map the status to qualifier_concept_id in observation domain?


What is a history of a disease which is “secondary”? Makes no sense. The primary and secondary is from the perspective of a visit: Was the diagnosis the reason for the visit and the activities therein. But the disease itself was either there or not.

Let us know.
