Hi @Aelan,
thanks for a good question.
This is the side effect of this decision
We “ressurrected” the CPT4 and HCPCS concepts outdated by the source, because these concepts were in a patient data those time.
But some of them become duplicated. So we’ll link earliest concept to the latest, that means concept_id =47719 will be Standard.
but if you query the data and want to define this particular anastomosis procedure, you need to keep both concepts in your concept set.
