Short Description:Non-follicular (diffuse) lymphoma, unspecified
Long Description:Non-follicular (diffuse) lymphoma, unspecified

Not Valid for Submission

ICD-10 C83.9 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of non-follicular (diffuse) lymphoma, unspecified. The code is NOT valid for the year 2019 for the submission of HIPAA-covered transactions.

Consider the following ICD-10 codes with a higher level of specificity:

  • C83.90 - Non-follicular (diffuse) lymphoma, unspecified, unspecified site
  • C83.91 - Non-follicular (diffuse) lymphoma, unspecified, lymph nodes of head, face, and neck
  • C83.92 - Non-follicular (diffuse) lymphoma, unspecified, intrathoracic lymph nodes
  • C83.93 - Non-follicular (diffuse) lymphoma, unspecified, intra-abdominal lymph nodes
  • C83.94 - Non-follicular (diffuse) lymphoma, unspecified, lymph nodes of axilla and upper limb
  • C83.95 - Non-follicular (diffuse) lymphoma, unspecified, lymph nodes of inguinal region and lower limb
  • C83.96 - Non-follicular (diffuse) lymphoma, unspecified, intrapelvic lymph nodes
  • C83.97 - Non-follicular (diffuse) lymphoma, unspecified, spleen
  • C83.98 - Non-follicular (diffuse) lymphoma, unspecified, lymph nodes of multiple sites
  • C83.99 - Non-follicular (diffuse) lymphoma, unspecified, extranodal and solid organ sites

Code Classification

  • Neoplasms (C00–D48)
    • Malignant neoplasms of lymphoid, hematopoietic and related tissue (C81-C96)
      • Non-follicular lymphoma (C83)

Information for Patients


Lymphoma

Also called: Non-Hodgkin 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 substances that attack cancer cells without harming 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.

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
