For example, medical conditions are linked to ICD-10-CM codes. Moreover, medications are mapped to RxNorm codes. Also, Amazon Comprehend Medical results infer SNOMED CT codes to provide medical insights, conditions, affected anatomy, test treatments, and procedures. Amazon Comprehend Medical also supports entity traits. For example, “Patient refused to take medication” has a negation entity trait.
