Diagnosis coding - Valiance Health

Diagnosis coding runs through POST /api/v1/search/. Send a clinical term; receive ranked candidate concepts in the vocabulary you name.

Vocabulary	Parameter value	Status
ICD-10-CM	`ICD10CM`	Available
SNOMED CT	`SNOMED`	Available
ICD-11	—	Soon. WHO ICD-11 main-condition rules already drive our DRG pipeline internally; public ICD-11 output joins after crosswalk curation.

Code a diagnosis to ICD-10

curl https://api.v2.healthproximate.com/api/v1/search/ \
  -H "X-API-Key: hpx_..." \
  -H "Content-Type: application/json" \
  -d '{
    "query": "community acquired pneumonia",
    "domain": "Condition",
    "vocabulary": "ICD10CM",
    "limit": 5
  }'

The response ranks candidate concepts with codes, names, and match scores. Filter by domain: "Condition" so procedure and drug concepts stay out of diagnosis results.

Code to SNOMED CT instead

Change one field: "vocabulary": "SNOMED". Same request, same response shape.

One search field serves both vocabularies. If you consume SNOMED and ICD-10 side by side, run the search per vocabulary — do not mix them in one call and split the results by code shape.

From diagnosis codes to a DRG

Diagnosis codes feed DRG classification: send your coded diagnoses (and procedures) to POST /api/v1/drg/classify/, or send raw clinical text to POST /api/v1/drg/agent/ and let the agent code first.
