Usage Examples

Basic Batch Mapping

Map concepts to common coding systems:

{
  "mappings": [
    {
      "concept_id": 201826,
      "target_vocabularies": ["ICD10CM", "ICD9CM"]
    },
    {
      "concept_id": 4182210,
      "target_vocabularies": ["ICD10CM", "HCPCS"]
    }
  ]
}

High-Quality Mappings Only

Get only exact, standard concept mappings:

{
  "mappings": [
    {
      "concept_id": 201826,
      "target_vocabularies": ["ICD10CM", "SNOMED"],
      "include_approximate": false,
      "standard_concepts_only": true,
      "max_mappings_per_concept": 3
    }
  ]
}

Research Context Mapping

Map concepts with context tracking:

{
  "mappings": [
    {
      "concept_id": 201826,
      "target_vocabularies": ["ICD10CM", "ICD9CM", "HCPCS"],
      "context_id": "diabetes_outcome_study_2024",
      "include_approximate": true,
      "mapping_types": ["Maps to", "Maps to value"]
    }
  ]
}

Important Notes

Batch size limit: Maximum 200 mapping requests per batch
Performance optimization: Batch processing is significantly more efficient than individual requests
Error isolation: Individual mapping failures don’t affect other mappings in the batch
Result ordering: Results are returned in the same order as input mappings
Confidence scores: Available when include_mapping_confidence=true but increase processing time
Context tracking: Use context_id for tracking related mappings across requests
