Excludes: benign brain tumors: code them as Central nervous system NOS, benign neoplasm
- A brain tumor occurs when abnormal cells form within the brain.
- There are two main types of tumors: malignant or cancerous tumors and benign tumors.
- Cancerous tumors can be divided into primary tumors that start within the brain, and secondary tumors that have spread from somewhere else, known as brain metastasis tumors.
SIGNS AND SYMPTOMS:
- The signs and symptoms of brain tumors are broad, and generally correspond to the area of the brain that they are located in. The brain is divided into 4 lobes, and each lobe or area has its own function. A tumor in any of these lobes may affect the area's performance. The location of the tumor is often linked to the symptoms experienced but each person may experience something different.
- Frontal lobe tumors may contribute to poor reasoning, inappropriate social behavior, personality changes, poor planning, lower inhibition, and decreased production of speech (Broca's area).
- Temporal lobe: Tumors in this lobe may contribute to poor memory, loss of hearing, difficulty in language comprehension (Wernicke's area).
- Parietal lobe: Tumors here may result in poor interpretation of languages, decreased sense of touch and pain, and poor spatial and visual perception.
- Occipital lobe: Damage to this lobe may result in poor or loss of vision.
- Cerebellum: Tumors in this area may cause poor balance, muscle movement, and posture.
- Brain stem: Tumors on this can affect blood pressure, swallowing, and heartbeat.
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.
"I have a patient who comes in with vague respiratory and gi symptoms. They did a chest xray and found a lung mass. They are now working him up for a probable lung ca, with mets to various places. In the old coding I would use ca-nyd. I actually use the ca nyd subcode a lot. I’ve talked to you about this before, because there is no ca nyd in icd10. You told me that you either have cancer or you don’t. For this particular patient I really wouldn’t have anything else I could code in icd10 for him. His symptoms are extremely vague. I don’t really like coding just symptoms, if there isn’t a proper admit diagnosis that fits better anyway. I found a “neoplasm of uncertain behavior (i.e. uncertain if benign or malignant), nos”, but I don’t really like that one. It doesn’t really fit. Is it possible to get something like “admit for workup of malignancy”, or something along those lines?" (Debbie, 12:40, 2018 October 4 (CDT)) How should this be coded?
