Dear all,

In this topic, the Vocabulary team will share the expected changes in the OHDSI vocabularies during the upcoming Feb 2025 release.

During this release, we expect some major changes previously discussed in the Community:

  • Rollback of CPT4/HCPCS mapping to the Visit domain (discussed here)
  • Rollback of SNOMED evaluation finding post-coordination and revision of pre-coordinated measurement domains both in SNOMED and in the source vocabularies (discussed here)

These changes are expected to affect the ETL and cohorts significantly, and we encourage users to review the files provided here and assess the potential impact.

I have attached the Excel files containing SNOMED changes in concept standard status, domains, and mapping in this post. Please, feel free to explore them and report any issues you have.

Dear all,

Here I attach Excel files containing expected changes in CPT4 and HCPCS concepts and their mapping. During this release:

  • We deprecate mappings to visits and make the source CPT4 and HCPCS concepts standard Procedures and Observations.
  • Instead, we introduce a new relationship ‘Has associated visit’ that now links CPT4 and HCPCS concepts with the Visit domain.

Please, feel free to explore.

Masha, this SNOMED mapping changes are helpful, but maybe it’s worth to share the source concepts (ICD mostly) mapping changes as well? So the users can see how their data mapping is changed?

Hi Dima,
Sure, I will share source vocabularies’ mapping changes as well, as soon as we finish our work on them.
