SNOMED-CT to ICD-10 Map

ColumnData TypeDescription

Maintenance Instructions​

This mapping is updated with each new relase of SNOMED CT US Edition which happens in March and September, and includes the annual ICD-10-CM update.

The mapping file can be found on the SNOMED CT United States Edition page. Click on the link to download the SNOMED CT to ICD-10-CM Mapping Resources which includes the human-readable version that contains all required data elements in a single TSV file.

The only clean-up required for the Tuva project is to remove the formatting from the maptarget (ICD-10-CM code) field (e.g. replace(maptarget,'.','')).

The HCC Suspecting data mart utilizes the default mapping guidance from NLM which specifies that the map priority rule of “TRUE” or “OTHERWISE TRUE” should be applied if nothing further is known about the patient’s condition. Other use-cases may need to further evaluate the map rules that consider a patient's age, gender, and comorbidities.
