The ICD-11 code 2A90.C corresponds to Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS), a type of non-Hodgkin lymphoma that affects mature T lymphocytes. PTCL-NOS is a heterogeneous group of T-cell lymphomas that do not fit into any specific subcategory based on their clinical and pathological characteristics. It is diagnosed by the presence of mature T-cell markers and absence of diagnostic features for other specific subtypes of PTCL.
PTCL-NOS typically presents with nodal or extranodal involvement, and may have varying clinical courses and responses to treatment. The exact cause of PTCL-NOS is unknown, but risk factors may include immune suppression, certain viruses, and genetic mutations. It can affect individuals of any age, but is more common in adults than children.
The prognosis for patients with PTCL-NOS can vary widely depending on various factors such as age, stage of disease, and response to treatment. Treatment may include chemotherapy, radiation therapy, or stem cell transplantation. Close monitoring and follow-up care are essential for managing PTCL-NOS and assessing response to treatment.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 2A90.C for Peripheral T-cell lymphoma, not otherwise specified is 78448006. This code specifically identifies cases of peripheral T-cell lymphoma where the subtype is not further specified. Peripheral T-cell lymphoma is a rare and aggressive type of non-Hodgkin lymphoma that affects T-cells in the lymphatic system. These lymphomas often present with symptoms such as enlarged lymph nodes, fever, and weight loss. Being able to accurately code and classify such cases using SNOMED CT can aid in improved data analysis, research, and patient care. By utilizing standardized codes like 78448006, healthcare providers can ensure consistency in reporting and facilitate communication among different healthcare systems and professionals. This harmonization of coding systems is essential for accurate and efficient healthcare management and research efforts.
In the United States, ICD-11 is not yet in use. The U.S. is currently using ICD-10-CM (Clinical Modification), which has been adapted from the WHO’s ICD-10 to better suit the American healthcare system’s requirements for billing and clinical purposes. The Centers for Medicare and Medicaid Services (CMS) have not yet set a specific date for the transition to ICD-11.
The situation in Europe varies by country. Some European nations are considering the adoption of ICD-11 or are in various stages of planning and pilot studies. However, as with the U.S., full implementation may take several years due to similar requirements for system updates and training.
🔎 Symptoms
Symptoms of 2A90.C, also known as Peripheral T-cell lymphoma, not otherwise specified, can vary widely among individuals. Common symptoms of this type of lymphoma include swollen lymph nodes, which may be painless or tender to the touch. Some individuals may also experience unexplained weight loss, fever, and night sweats, which are known as B symptoms in the medical community.
Moreover, individuals with Peripheral T-cell lymphoma, not otherwise specified, may present with symptoms related to the involvement of extranodal sites. This can include skin involvement, leading to the development of skin lesions or a rash. Additionally, some individuals may experience gastrointestinal symptoms such as abdominal pain, diarrhea, or vomiting if the lymphoma affects the digestive system.
Furthermore, as Peripheral T-cell lymphoma, not otherwise specified, is a systemic disease, it can manifest with generalized symptoms that affect the entire body. Fatigue, weakness, and a general sense of malaise are commonly reported symptoms in individuals with this type of lymphoma. Additionally, some individuals may experience shortness of breath or coughing if the lymphoma affects the lungs or chest. Early recognition and prompt evaluation of these symptoms are crucial for a timely diagnosis and appropriate management of the condition.
🩺 Diagnosis
Diagnosis methods for 2A90.C, also known as Peripheral T-cell lymphoma, not otherwise specified, typically involve a combination of medical history assessment, physical examination, laboratory tests, imaging studies, and biopsy procedures.
Medical history assessment plays a crucial role in the diagnosis of Peripheral T-cell lymphoma, as it helps healthcare providers understand the patient’s symptoms, past medical conditions, family history, and potential risk factors for lymphoma. Patients are often asked about symptoms such as fever, night sweats, unexplained weight loss, fatigue, and swollen lymph nodes.
A comprehensive physical examination is usually conducted to evaluate the patient’s overall health, identify any abnormal signs or symptoms, and assess the extent of lymph node enlargement. Healthcare providers may palpate various lymph node groups, examine the skin for rashes or lesions, and check for hepatosplenomegaly (enlargement of the liver and spleen), as these are common manifestations of lymphoma. Other physical signs indicative of Peripheral T-cell lymphoma include generalized weakness, shortness of breath, and easy bruising or bleeding.
💊 Treatment & Recovery
Treatment options for Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) typically involve a combination of chemotherapy and targeted therapy. The choice of treatment may vary depending on individual factors such as the extent of the disease, age, and overall health of the patient. Chemotherapy regimens commonly used for PTCL-NOS may include CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) or more intensive regimens like EPOCH (etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin).
For patients with relapsed or refractory PTCL-NOS, treatment options may include high-dose chemotherapy followed by stem cell transplant. This approach aims to eradicate the remaining cancer cells and restore healthy blood cell function. Additionally, targeted therapies such as brentuximab vedotin or mogamulizumab may be considered for patients who have not responded well to conventional treatments. These therapies specifically target certain molecules on the surface of cancer cells, leading to their destruction.
In some cases, participation in clinical trials may offer promising new treatment options for PTCL-NOS. These trials test novel therapies or treatment combinations to improve outcomes for patients with this challenging disease. Patients are encouraged to discuss all available treatment options with their healthcare team to determine the most appropriate course of action based on their individual circumstances. Regular monitoring and follow-up care are essential to assess response to treatment and manage any potential side effects.
🌎 Prevalence & Risk
In the United States, the prevalence of Peripheral T-cell lymphoma, not otherwise specified (2A90.C) is estimated to be relatively low compared to other types of lymphomas. However, due to the rarity of this specific subtype, accurate prevalence data is difficult to obtain. The exact number of cases diagnosed each year is uncertain, but it is believed to represent a small percentage of all lymphoma cases.
In Europe, the prevalence of Peripheral T-cell lymphoma, not otherwise specified is slightly higher compared to the United States. European countries have reported a slightly higher prevalence of this subtype, but still, overall, it remains a rare form of lymphoma. The exact prevalence rates vary among different European regions, with certain countries showing higher rates than others.
In Asia, the prevalence of Peripheral T-cell lymphoma, not otherwise specified is difficult to determine due to limited data and research on this particular subtype. Some studies have suggested that the incidence of this subtype may be lower in certain Asian populations compared to Western countries.
