Clinical Classification

• Clinical Category is Hodgkin lymphoma

• CCSR Category Code: NEO057

• Outpatient Default CCSR: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

Clinical Information

  an obsolete term referring to a hodgkin lymphoma that lacks inflammatory elements.

C81.73 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V42.0 applicable from 10/01/2024 through 09/30/2025.

MS-DRG	MS-DRG Title	MCD	Relative Weight
820	Lymphoma and Leukemia with Major O.R. Procedures with MCC	17	5.8219
821	Lymphoma and Leukemia with Major O.R. Procedures with CC	17	2.2322
822	Lymphoma and Leukemia with Major O.R. Procedures without CC/MCC	17	1.1436
823	Lymphoma and Non-Acute Leukemia with Other Procedures with MCC	17	4.6792
824	Lymphoma and Non-Acute Leukemia with Other Procedures with CC	17	2.1993
825	Lymphoma and Non-Acute Leukemia with Other Procedures without CC/MCC	17	1.2307
840	Lymphoma and Non-Acute Leukemia with MCC	17	3.1894
841	Lymphoma and Non-Acute Leukemia with CC	17	1.5679
842	Lymphoma and Non-Acute Leukemia without CC/MCC	17	1.0518

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

• ICD-9-CM Code: 201.03 - Hodgkins paragran abdom
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.
• ICD-9-CM Code: 201.13 - Hodgkins granulom abdom
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.
• ICD-9-CM Code: 201.23 - Hodgkins sarcoma abdom
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

Hodgkin Lymphoma

What is Hodgkin lymphoma?

Hodgkin lymphoma, also called Hodgkin disease, is a type of cancer that develops in the lymph system. Your lymph system is part of your immune system. It helps protect your body from infection and disease.

The lymph system is made up of tissues and organs that produce, store, and carry white blood cells. It includes your:

• Bone marrow
• Lymph nodes
• Lymphatic vessels
• Spleen
• Thymus
• Tonsils

Hodgkin lymphoma is one of the main types of lymphoma. The other is non-Hodgkin lymphoma. Each type starts in different types of white blood cells.

What causes Hodgkin lymphoma?

The cause of Hodgkin lymphoma is unknown. But there are certain people who are at higher risk of developing it.

Who is more likely to develop Hodgkin lymphoma?

Certain factors can make you more likely to develop Hodgkin lymphoma:

• Age. Hodgkin lymphoma is most common in early adulthood (age 20-39 years) and in late adulthood (age 65 years and older).
• Being male. The risk of adult Hodgkin lymphoma is slightly higher in males than in females.
• Past Epstein-Barr virus (EBV) infection. Having an infection with EBV as a young child or teenager increases your risk of Hodgkin lymphoma.
• A family history of Hodgkin lymphoma. Having a parent or sibling with Hodgkin lymphoma increases your risk of developing it.

What are the symptoms of Hodgkin lymphoma?

The signs and symptoms of Hodgkin lymphoma may include:

• Painless, swollen lymph nodes in the neck, underarm, or groin
• Fever for no known reason
• Drenching night sweats (very heavy sweating during sleep)
• Weight loss for no known reason in the past 6 months
• Itchy skin, especially after bathing or drinking alcohol
• Fatigue

How is Hodgkin lymphoma diagnosed?

To find out if you have Hodgkin lymphoma, your provider:

• Will ask about your symptoms and medical history. This will include checking for signs of disease, such as lumps or anything else that seems unusual.
• May order some lab tests, such as:
  • Complete blood count
  • Blood chemistry studies
  • Lactate dehydrogenase (LDH) test
  • Erythrocyte sedimentation rate (ESR) test
  • Blood tests to rule out other medical conditions
  • May do imaging tests such as a CT and PET (positron emission tomography) scans
  • May do a lymph node biopsy

What are the treatments for Hodgkin lymphoma?

Treatments for Hodgkin lymphoma include:

• Chemotherapy
• Radiation therapy
• Targeted therapy, which uses drugs or other substances that attack specific cancer cells with less harm to normal cells
• Cancer immunotherapy

Hodgkin lymphoma can usually be cured if it is found and treated early.
