ICD-10: C82.3

Follicular lymphoma grade IIIa, classified under ICD-10 code C82.3, is a subtype of non-Hodgkin lymphoma (NHL) characterized by specific clinical presentations, signs, symptoms, and patient characteristics. Understanding these aspects is crucial for diagnosis, treatment, and management of the disease.

Clinical Presentation

Follicular lymphoma is typically indolent, meaning it often progresses slowly. However, grade IIIa indicates a more aggressive form of the disease compared to lower grades. Patients may present with:

• Lymphadenopathy: Swollen lymph nodes are often the first noticeable sign. These can be localized or generalized, affecting multiple regions such as the neck, armpits, or groin.
• Splenomegaly: Enlargement of the spleen may occur, which can be detected during a physical examination or imaging studies.
• B Symptoms: Patients may experience systemic symptoms known as B symptoms, which include:
• Unexplained fever
• Night sweats
• Significant weight loss (more than 10% of body weight over six months)

Signs and Symptoms

The signs and symptoms of follicular lymphoma grade IIIa can vary widely among patients but commonly include:

• Fatigue: A persistent feeling of tiredness that does not improve with rest.
• Itching: Some patients report pruritus, which can be generalized or localized.
• Abdominal discomfort: This may arise from splenomegaly or lymphadenopathy affecting abdominal organs.
• Anemia: Patients may present with signs of anemia, such as pallor or shortness of breath, due to bone marrow involvement.
• Increased susceptibility to infections: This can occur due to compromised immune function.

Patient Characteristics

Certain demographic and clinical characteristics are often associated with patients diagnosed with follicular lymphoma grade IIIa:

• Age: Follicular lymphoma typically affects adults, with a median age of diagnosis around 60 years. However, it can occur in younger individuals.
• Gender: There is a slight male predominance in the incidence of follicular lymphoma.
• Ethnicity: The disease is more common in Caucasians compared to other ethnic groups.
• History of autoimmune diseases: Some patients may have a history of autoimmune conditions, which have been associated with an increased risk of developing lymphomas.

Diagnosis and Staging

Diagnosis of follicular lymphoma grade IIIa involves a combination of clinical evaluation, imaging studies (such as CT scans), and histopathological examination of lymph node biopsies. The grading is determined by the proportion of large cells (centroblasts) present in the tissue sample, with grade IIIa indicating a higher percentage of these cells compared to lower grades.

Conclusion

Follicular lymphoma grade IIIa presents with a range of clinical features, including lymphadenopathy, systemic symptoms, and signs of anemia. Understanding these characteristics is essential for timely diagnosis and effective management. Given its more aggressive nature compared to lower-grade follicular lymphomas, early intervention and appropriate treatment strategies are critical for improving patient outcomes. Regular follow-up and monitoring are also important to manage potential complications and disease progression effectively.

Follicular lymphoma grade IIIa, classified under ICD-10 code C82.3, is a subtype of non-Hodgkin lymphoma characterized by specific histological features and clinical criteria. The diagnosis of follicular lymphoma, particularly grade IIIa, involves a combination of clinical evaluation, imaging studies, and histopathological examination. Below are the key criteria used for diagnosis:

Clinical Presentation

1. Symptoms: Patients may present with painless lymphadenopathy, which is the most common symptom. Other symptoms can include fever, night sweats, weight loss, and fatigue, often referred to as "B symptoms" in lymphoma.

2. Physical Examination: A thorough physical examination is essential to identify enlarged lymph nodes, spleen, or liver, which may indicate lymphatic involvement.

Imaging Studies

1. CT Scans: Computed tomography (CT) scans of the chest, abdomen, and pelvis are typically performed to assess the extent of lymphadenopathy and any organ involvement.

2. PET Scans: Positron emission tomography (PET) scans may be utilized to evaluate metabolic activity in lymph nodes and to help stage the disease.

Histopathological Criteria

1. Biopsy: A definitive diagnosis of follicular lymphoma requires a biopsy of the affected lymph node or tissue. The biopsy specimen is examined microscopically.

2. Histological Features:
   - Follicular Architecture: The presence of neoplastic follicles is a hallmark of follicular lymphoma. In grade IIIa, there is a predominance of large cells within the follicles.
   - Cell Type: The neoplastic cells are typically B-cell in origin, characterized by the expression of CD10, BCL2, and BCL6 markers.
   - Grade Assessment: Follicular lymphoma is graded based on the proportion of large cells (centroblasts) present. Grade IIIa indicates that there are more than 15 centroblasts per high-power field (HPF) but less than 50% of the neoplastic cells are large.

3. Immunophenotyping: Flow cytometry or immunohistochemistry is used to confirm the B-cell lineage and to assess the expression of specific surface markers.

Molecular and Genetic Testing

1. Cytogenetics: The presence of the t(14;18) chromosomal translocation, which involves the BCL2 gene, is commonly associated with follicular lymphoma and can be detected through fluorescence in situ hybridization (FISH) or polymerase chain reaction (PCR) techniques.

2. Minimal Residual Disease Testing: In some cases, testing for minimal residual disease (MRD) may be performed to assess treatment response and disease status.

Staging

The Ann Arbor staging system is often used to determine the extent of the disease, which is crucial for treatment planning. Staging involves assessing the number of lymph node regions involved and whether there is extranodal involvement.

Conclusion

The diagnosis of follicular lymphoma grade IIIa (ICD-10 code C82.3) is a multifaceted process that integrates clinical evaluation, imaging studies, histopathological examination, and molecular testing. Accurate diagnosis is essential for determining the appropriate treatment strategy and prognosis for patients with this type of lymphoma. For further details on coding and billing related to this diagnosis, resources such as the CMS Manual System and specific coding forums may provide additional insights[1][2][3][4][5].

Follicular lymphoma grade IIIa, classified under ICD-10 code C82.3, is a subtype of non-Hodgkin lymphoma (NHL) characterized by the proliferation of follicle center (germinal center) B-cells. This type of lymphoma is known for its indolent nature, but grade IIIa indicates a more aggressive behavior compared to lower grades. The treatment approaches for this condition are multifaceted and depend on various factors, including the patient's overall health, the extent of the disease, and specific clinical features.

Standard Treatment Approaches

1. Chemotherapy

Chemotherapy remains a cornerstone of treatment for follicular lymphoma grade IIIa. Common regimens include:

• R-CHOP: This regimen combines Rituximab (a monoclonal antibody) with Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone. R-CHOP is often the first-line treatment for advanced-stage follicular lymphoma and has shown significant efficacy in improving patient outcomes[9][10].

• R-CVP: This regimen includes Rituximab, Cyclophosphamide, Vincristine, and Prednisone. It is typically used for patients who may not tolerate more intensive chemotherapy[9].

2. Targeted Therapy

Targeted therapies have emerged as important options for treating follicular lymphoma:

• Rituximab: As a monoclonal antibody targeting CD20, Rituximab is frequently used in combination with chemotherapy or as a standalone treatment for patients with relapsed disease[9][10].

• Idelalisib: This is an oral inhibitor of the PI3K pathway, used in combination with Rituximab for patients who have received at least two prior therapies[9].

3. Radiation Therapy

Radiation therapy may be employed in specific scenarios, particularly for localized disease or as a palliative measure to relieve symptoms. It is not typically the primary treatment for advanced-stage follicular lymphoma but can be effective in localized cases or for symptomatic control[4][9].

4. Stem Cell Transplantation

For patients with relapsed or refractory follicular lymphoma, autologous stem cell transplantation may be considered. This approach is generally reserved for younger patients or those with a good performance status, as it involves high-dose chemotherapy followed by the reinfusion of the patient’s own stem cells[9].

5. Watchful Waiting

In cases where the lymphoma is asymptomatic and not rapidly progressing, a strategy of "watchful waiting" may be adopted. This involves regular monitoring without immediate treatment, as many patients with follicular lymphoma can live for years without treatment[9][10].

6. Clinical Trials

Participation in clinical trials may also be an option for patients, providing access to new therapies and treatment strategies that are not yet widely available. These trials often explore novel agents or combinations that may improve outcomes for patients with follicular lymphoma[9].

Conclusion

The treatment of follicular lymphoma grade IIIa (ICD-10 code C82.3) is tailored to the individual patient, considering factors such as disease stage, patient health, and treatment goals. A combination of chemotherapy, targeted therapies, and possibly radiation or stem cell transplantation forms the basis of management strategies. Ongoing research and clinical trials continue to evolve the landscape of treatment options, offering hope for improved outcomes in this patient population. For patients and healthcare providers, staying informed about the latest advancements in treatment is crucial for optimizing care.

Clinical Description of Follicular Lymphoma Grade IIIa (ICD-10 Code C82.3)

Overview of Follicular Lymphoma

Follicular lymphoma is a type of non-Hodgkin lymphoma (NHL) that originates in the lymphatic system, specifically from B-cells, which are a type of white blood cell. It is characterized by the proliferation of neoplastic follicle center (germinal center) cells. Follicular lymphoma is generally indolent, meaning it tends to grow slowly, but it can transform into a more aggressive form over time. The World Health Organization (WHO) classifies follicular lymphoma into several grades based on histological features, with grade IIIa being one of the more advanced stages.
