Certified Hematology and Oncology Coder (CHONC) The CHONC demands precision with ICD-10-CM coding for malignancies, chemotherapy regimens, and complication tracking across inpatient and outpatient settings. Incoming test-takers should grasp TNM staging nomenclature, recognize how treatment intent (curative vs. palliative) shifts code selection, and understand sequencing rules when multiple cancers or therapy side effects are documented. Mock exams reveal gaps in neoplasm hierarchy faster than self-study alone.
