Sentence Entity Resolver for billable ICD10-CM HCC codes

Description

This model maps extracted medical entities to ICD10-CM codes using chunk embeddings (augmented with synonyms, four times richer than previous resolver). It also adds support of 7-digit codes with HCC status.

For reference: http://www.formativhealth.com/wp-content/uploads/2018/06/HCC-White-Paper.pdf

Predicted Entities

Outputs 7-digit billable ICD codes. In the result, look for aux_label parameter in the metadata to get HCC status. The HCC status can be divided to get further information: billable status, hcc status, and hcc score.

For example, in the example shared below the billable status is 1, hcc status is 1, and hcc score is 8.

  .setOutputCol("document")

sbert_embedder = BertSentenceEmbeddings\
     .pretrained("sbiobert_base_cased_mli","en","clinical/models")\
     .setInputCols(["document"])\
     .setOutputCol("sbert_embeddings")

     .setInputCols(["document", "sbert_embeddings"]) \
     .setOutputCol("icd10cm_code")\
     .setDistanceFunction("EUCLIDEAN").setReturnCosineDistances(True)

bert_pipeline_icd = PipelineModel(
    stages = [
    document_assembler,

model = nlpPipeline.fit(spark.createDataFrame([["metastatic lung cancer"]]).toDF("text"))

results = model.transform(data)
