Code Classification

  • Neoplasms
    (C00–D49)
    • Malignant neoplasms of lymphoid, hematopoietic and related tissue
      (C81-C96)
      • Other specified and unspecified types of non-Hodgkin lymphoma
        (C85)

C85.99 is a billable diagnosis code used to specify a medical diagnosis of non-hodgkin lymphoma, unspecified, extranodal and solid organ sites. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like C85.99 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Patient Education


Lymphoma

Lymphoma is a cancer of a part of the immune system called the lymph system. There are many types of lymphoma. One type is Hodgkin disease. The rest are called non-Hodgkin lymphomas.

Non-Hodgkin lymphomas begin when a type of white blood cell, called a T cell or B cell, becomes abnormal. The cell divides again and again, making more and more abnormal cells. These abnormal cells can spread to almost any other part of the body. Most of the time, doctors don't know why a person gets non-Hodgkin lymphoma. You are at increased risk if you have a weakened immune system or have certain types of infections.

Non-Hodgkin lymphoma can cause many symptoms, such as :

  • Swollen, painless lymph nodes in the neck, armpits or groin
  • Unexplained weight loss
  • Fever
  • Soaking night sweats
  • Coughing, trouble breathing or chest pain
  • Weakness and tiredness that don't go away
  • Pain, swelling or a feeling of fullness in the abdomen

Your doctor will diagnose lymphoma with a physical exam, blood tests, a chest x-ray, and a biopsy. Treatments include chemotherapy, radiation therapy, targeted therapy, biological therapy, or therapy to remove proteins from the blood. Targeted therapy uses drugs or other substances that attack specific cancer cells with less harm to normal cells. Biologic therapy boosts your body's own ability to fight cancer. If you don't have symptoms, you may not need treatment right away. This is called watchful waiting.
