Anastomosis, choledochal cyst, without excision


(Aelan Park) #1

Hi all,

I have a question
I just found now some strange.

In CPT 4, they(Anastomosis, choledochal cyst, without excision) are the same name, but have different concept ID (42733593,42741059) and both are standard.

Which one is right?!

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We “ressurrected” the CPT4 and HCPCS concepts outdated by the source, because these concepts were in a patient data those time.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.
