We are working on ETL for EHR data for outpatient encounters. What is the right way to convert billing ICD10 codes to OMOP CDM? We convert them to standard concepts and put them into a condition_occurance table. But we noticed that some of ICD 10 codes are mapped to concepts not from the “Condition” domain.
There are some examples:
- Z01.82 - Encounter for allergy testing
- V26.33 - Genetic counseling
Some ICD10 codes also have “map to value” relationships:
- R71.8 - Other abnormality of red blood cells
- R76.8 - Other specified abnormal immunological findings in serum
What is the right way to incorporate this information into OMOP CDM?
