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:
- risk of obtaining tissue is very high
- plan would be palliative regardless
- 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
"work-up for cancer"
If the cancer has not been confirmed then it should not be coded as cancer. Code relevant test abnormal test results or symptoms.

Malignancy with Metastasis
Metastasis and their primary tumor should be coded in combination because the codes for mets don't specify the primary site, only the site of the mets.
Codes for the mets can be found at:
Metastasis codes: |
- If the site of the mets isn't in the list, use Site NOS, metastatic malignancy to it (also code primary site)
- If there are mets to multiple sites, then combine all together the primary malignancy code to the codes for the different sites of the mets.
- If the mets are in the other of a paired organ (e.g. the other kidney), then code both the primary and the metastatic codes, and link them together
