Using ICD10 Malignancy Codes as a Comorbid Diagnosis

• Any cancer/malignancy (either a "solid tumor" or a leukemia/lymphoma/bone marrow malignancy/"liquid tumor", i.e. any ICD10 code from C00-C99) can be a comorbid diagnosis --- BUT it's vital to distinguish malignancies in this category based on whether they are believed to be cured or not.

• If it's still present (or believed to be present), then just include the code for the specific cancer as a comorbid diagnosis.
• If INSTEAD, it's presumed cured, then in the "bin" of comorbid diagnoses combine the code for the specific cancer with this code: Past history, cancer (any type), believed cured

Regarding Presumptive Diagnosis of Malignancy

• Rarely a presumptive diagnosis is made without any tissue confirmation. This generally occurs with: (i) risk of obtaining tissue is very high, (ii) plan would be palliative regardless, or (iii) patient would refuse care regardless.
• Our issue for how to code a presumed malignancy without definitive histopathologic proof is this:
  • If the physicians are going to proceed with a treatment plan without that definitive histopathologic proof --- then code whatever is their best guess about what is present. Example: believed to be lung cancer with a big brain met, and they've decided NOT to do any biopsy but to give palliative radiation therapy, then you'd code lung cancer, and met to brain.
  • If the plan is to obtain a definitive histopathologic diagnosis soon or in the future, then instead code: Neoplasm of uncertain behavior (i.e. not clear if benign or malignant), NOS
