2025 ICD-10-CM code C95.9
(Active) Effective Date: N/A Malignant neoplasms of lymphoid, hematopoietic and related tissue - C95.9 2: Neoplasms (C00-D49) Feed
Leukemia, unspecified.
The medical necessity for the workup and treatment of leukemia is based on the patient's signs, symptoms, and confirmed diagnosis.The type of treatment (chemotherapy, radiation, stem cell transplant, etc.) will determine specific medical necessity requirements, which may vary by payer.
The provider diagnoses leukemia based on the patient’s history, signs and symptoms, and physical examination. Common laboratory tests include CBC, peripheral smear, and blood chemistries. The provider can perform biopsy or fine needle aspiration biopsy of the lesion. Imaging studies include CT, MRI, and PET scans as well as ultrasound.
- 2: Neoplasms (C00-D49)
- Malignant neoplasms (C00-C96)Malignant neoplasms, stated or presumed to be primary (of specified sites), and certain specified histologies, except neuroendocrine, and of lymphoid, hematopoietic and related tissue (C00-C75)Malignant neoplasms of lymphoid, hematopoietic and related tissue (C81-C96)
In simple words: Leukemia is a cancer of the blood cells. It happens when abnormal blood cells grow too fast and replace healthy blood cells. This code is used when the doctor doesn't say what specific type of leukemia it is.
Leukemia refers to cancers of the blood cells.It is characterized by the rapid growth of abnormal blood cells. This uncontrolled growth takes place in your bone marrow, where most of your body's blood is made.Leukemia cells are usually immature (still developing) white blood cells. There are many types of leukemia depending on the cells involved. This code is used when the provider documents that the patient has leukemia but does not specify the type.
Example 1: A 65-year-old patient presents with fatigue, unexplained weight loss, and frequent infections.Blood work shows abnormal white blood cell counts.A bone marrow biopsy is performed, and the pathology report confirms leukemia, but no specific type is identified. C95.9 is used., A 25-year-old patient experiences easy bruising, swollen lymph nodes, and bone pain.Diagnostic testing reveals leukemia, but further testing is needed to determine the specific type. C95.9 is used until a definitive diagnosis is made., A patient's medical record from another facility indicates a diagnosis of leukemia, but the specific type is not documented in the current record.C95.9 is appropriate in this scenario.
Documentation should include signs, symptoms leading to the diagnosis, results of blood tests (CBC, peripheral smear), bone marrow biopsy results, imaging results (if applicable), and any other relevant clinical findings.
