| **Note:** In some countries, ICD10 is extended by local codes. For example, in the US a derivative system called ICD10CM is in use, in Germany a similar ICD10GM. Even though many of the codes are shared, those country-specific coding systems are separate and distinct vocabularies in their own right in the OMOP Standardized Vocabularies. | **Note:** In some countries, ICD10 is extended by local codes.

| ICD10 concepts are non-Standard Concepts and therefore are mapped to Standard Concepts through records in the CONCEPT_RELATIONSHIP table. All such mappings point to SNOMED-based concepts. Most of these SNOMED Concepts are in the Condition Domain, but despite the fact that ICD10 is a "Classification of Disease" some of them get mapped to Procedure, Measurement and Observation Domain Concepts. All mappings are manually maintained by a team of curators. | ICD10 concepts are non-Standard Concepts and therefore are mapped to Standard Concepts through records in the CONCEPT_RELATIONSHIP table.

| - | Most mappings establish one-to-one equivalence between the Concepts. However, some ICD10 Concepts are pre-coordinated (consist of several semantic components), contain negations, declarations about conditions at an unspecified time in the past (e.g. medical history of), declarations about people other than the patient (e.g. family history), lab test findings, mixed mother/child conditions or Observations. All these cases are properly handled as described in the XXX. | + | Most mappings establish one-to-one equivalence between the Concepts.
