Usage Examples

​
Basic Concept Mapping

Map SNOMED concepts to ICD-10-CM: 
{
  "source_concepts": [201826],
  "target_vocabulary": "ICD10CM",
  "mapping_type": "equivalent"
}

​
Cross-System Integration

Map multiple concepts for EHR integration: 
{
  "source_concepts": [201826, 192671, 443729],
  "target_vocabulary": "ICD10CM",
  "mapping_type": "direct",
  "include_invalid": false
}

​
Drug Mapping

Map drug concepts from SNOMED to RxNorm: 
{
  "source_concepts": [387517004, 108774000],
  "target_vocabulary": "RXNORM", 
  "mapping_type": "equivalent"
}
