ICD-11 code 2E65.4 refers to mixed ductal and lobular carcinoma in situ of the breast. This code is used by healthcare providers to classify and code cases of cancer where both ductal and lobular carcinomas are present within the breast tissue. Carcinoma in situ means that the cancer is in its earliest stage and has not spread beyond the breast ducts or lobules.
Ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS) are two common types of breast cancer that can either occur alone or together in rare cases. When both types of carcinoma are present in the breast tissue, it is classified as mixed ductal and lobular carcinoma in situ. Diagnosis of this type of cancer is typically done through a combination of imaging tests, biopsies, and pathology reports.
Treatment options for mixed ductal and lobular carcinoma in situ may include surgery, radiation therapy, hormone therapy, or a combination of these treatments. The prognosis for patients with this type of cancer is generally favorable, as the cancer is typically non-invasive and has not spread to other parts of the body. Regular monitoring and follow-up care are recommended to ensure early detection of any potential recurrence or progression of the disease.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 2E65.4, which indicates mixed ductal and lobular carcinoma in situ of the breast, is 254686006. This code specifically refers to the presence of both ductal and lobular carcinoma in situ within the breast, providing a more precise classification for healthcare providers and researchers. SNOMED CT codes are standardized clinical terminology used globally to accurately describe various aspects of patient care, including diagnoses, procedures, and findings. The inclusion of specific details in the SNOMED CT code allows for better communication among healthcare professionals, facilitating accurate diagnosis and treatment of patients with this particular type of breast cancer. Utilizing SNOMED CT codes in conjunction with ICD-11 codes helps streamline documentation, billing, and research efforts in the medical field, ultimately improving patient outcomes.
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 2E65.4, also known as mixed ductal and lobular carcinoma in situ of the breast, may include changes in the appearance or feel of the breast tissue. Patients may notice a thickening or lump in the breast, changes in the nipple, such as inversion or discharge, or skin changes like redness or dimpling.
Another common symptom of 2E65.4 is nipple discharge, especially if it is bloody or occurs without squeezing the nipple. Patients may also experience breast pain or discomfort, although this symptom is less common. It is important to note that these symptoms can be indicative of various breast conditions, so it is essential to seek medical attention for a proper diagnosis.
In some cases, patients with 2E65.4 may not experience any symptoms at all, as this type of carcinoma is often detected through screening mammograms or biopsies. However, if any of the aforementioned symptoms are present, it is crucial to consult a healthcare provider promptly for further evaluation and appropriate management. Early detection and treatment can significantly improve outcomes for patients with mixed ductal and lobular carcinoma in situ of the breast.
🩺 Diagnosis
Diagnosis of 2E65.4 (Mixed ductal and lobular carcinoma in situ of the breast) typically begins with a physical examination and a detailed medical history to assess any symptoms or risk factors. Imaging tests such as mammograms, ultrasounds, and MRIs may be ordered to visualize any abnormalities in the breast tissue. These tests can help identify the presence of calcifications, lumps, or other suspicious areas that may indicate the presence of carcinoma in situ.
A biopsy is often performed to confirm the diagnosis of mixed ductal and lobular carcinoma in situ. During a biopsy, a sample of the suspicious tissue is removed and examined under a microscope by a pathologist. This allows for a definitive diagnosis of the type of carcinoma in situ present, as well as any characteristics that may impact treatment decisions. In some cases, additional tests such as a molecular analysis of the tumor tissue may be conducted to further characterize the cancer and guide treatment options.
Once a diagnosis of mixed ductal and lobular carcinoma in situ has been confirmed, additional tests may be ordered to evaluate the extent of the disease and determine the best course of treatment. This may include blood tests, genetic testing, and imaging scans to assess whether the cancer has spread beyond the breast tissue. The results of these tests can help healthcare providers develop a personalized treatment plan that is tailored to the individual patient’s needs and circumstances.
💊 Treatment & Recovery
Treatment for 2E65.4, mixed ductal and lobular carcinoma in situ of the breast, often involves a combination of therapies. Surgery is typically the first line of treatment, with options ranging from lumpectomy to mastectomy depending on the extent of the disease. Radiation therapy is often recommended following surgery to target any remaining cancer cells and reduce the risk of recurrence.
In some cases, hormone therapy may be recommended for patients with hormone receptor-positive tumors. This treatment works by blocking the effects of estrogen on cancer cells, slowing their growth and reducing the risk of recurrence. Chemotherapy may also be considered for certain patients, particularly those with high-risk features or aggressive tumors.
Recovery from 2E65.4 can vary depending on the individual and the specific treatment plan. Following surgery, patients may experience physical side effects such as pain, swelling, and limited mobility. Radiation therapy can cause skin irritation and fatigue, while hormone therapy may lead to menopausal symptoms such as hot flashes and mood swings. It is important for patients to communicate openly with their healthcare team about any concerns or side effects they may be experiencing during the recovery process.
