Yeah, that’s something that does happen, even though very rarely: Duplicates in SNOMED. The first one is SNOMED International, and it’s the one you should use. The second one is from SNOMED UK. It will eventually be de-duplicated and removed.
How do you know which is the right one? Unfortunately we don’t have a good way for that. Here are the tricks I am using:
- Check the concept_code. The shorter one is the SNOMED International one. This will make you pick 36714388.
- Check the hierarchy in CONCEPT_ANCESTOR. Usually, the good concept has lots of ancestors and descendants, the bad one doesn’t. In this case this doesn’t work, both ancestors and descendants are identical.
