  • Diagnosis record of HES (ICD-10-CM D72.11) anytime during 01 October 2020 to 30 June 2023
  • At least 12 months of patient insurance record prior to first HES record.

You may not qualify if:

  • Any mutation in PDGFRA, PDGFRB or FGFR1 genes (to exclude clonal HES).
  • History of BCR-ABL tyrosine kinase inhibitor use: imatinib, dasatinib, nolitinib, bosutinib, ponatinib, asciminib (to exclude clonal HES)
  • History of myeloid leukemia, myeloproliferative disorder, myelodysplastic disorder, myelomonocytic leukemia, acute erythroid leukemia, acute megakaryoblastic leukaemia, acute panmyelosis with myelofibrosis, and other specified leukaemias (to exclude reactive HES)
