Breast cancer diagnosis is a critical area in healthcare, and accurate coding is essential for proper billing, data analysis, and research. The International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) provides a standardized system for classifying diagnoses and procedures. Within this system, code C50.919 plays a specific role in the classification of breast cancer in females. This article delves into the details of ICD-10-CM code C50.919, offering a comprehensive understanding for healthcare professionals and anyone seeking clarity on breast cancer diagnosis codes.
Decoding ICD-10-CM Code C50.919
ICD-10-CM code C50.919 is categorized as “Malignant neoplasm of unspecified site of unspecified female breast“. Let’s break down this description to fully understand its meaning:
- Malignant Neoplasm: This term indicates that the condition is cancerous. A neoplasm is an abnormal growth of tissue, and “malignant” specifies that this growth is invasive and has the potential to spread to other parts of the body (metastasize).
- Unspecified Site: This part of the code means that the precise location of the cancer within the breast is not specified. While other ICD-10-CM codes exist to pinpoint locations like the nipple, areola, or specific quadrants of the breast, C50.919 is used when the exact location within the breast is not documented.
- Unspecified Female Breast: This clearly indicates that the code applies to female patients and that the laterality (whether it’s the right or left breast) is not specified. This code is used when the documentation doesn’t detail whether the cancer is in the right or left breast.
It’s important to note that C50.919 is a billable/specific code. This means it is detailed enough to be used for reimbursement purposes in healthcare claims. The code is applicable to the 2025 ICD-10-CM edition, effective from October 1, 2024, and has remained consistent in versions dating back to 2016.

Who Does C50.919 Apply To?
The ICD-10-CM coding guidelines explicitly state that C50.919 is applicable to female patients. This specificity is crucial in medical coding to ensure accurate patient records and appropriate billing based on gender. While breast cancer can occur in males, different ICD-10-CM codes are designated for male breast cancer diagnoses.
Synonyms and Related Terms for C50.919
Understanding the synonyms and related terms associated with C50.919 can be helpful in interpreting medical documentation and ensuring accurate code assignment. Some approximate synonyms for “Malignant neoplasm of unspecified site of unspecified female breast” include:
- Breast cancer
- Cancer of the female breast
- Female breast cancer
- Malignant neoplasm of female breast
- Primary invasive malignant neoplasm of female breast
Furthermore, the original code listing provides a comprehensive list of related terms, including specific types and stages of breast cancer. These terms, such as “Infiltrating duct carcinoma of breast” or “Female inflammatory breast cancer,” while more specific, fall under the broader category of breast cancer and highlight the importance of accurate and detailed diagnosis for appropriate coding.
History of Code C50.919
The ICD-10-CM code C50.919 has been in use since 2016, with no changes through the 2025 edition. This stability is important for consistent data tracking and analysis over time. The consistent application of this code ensures that healthcare providers and researchers can reliably utilize it for years of data comparison and trend analysis in breast cancer cases.
The Importance of Accurate Breast Cancer ICD-10 Coding
Accurate use of breast cancer ICD-10 diagnosis codes, including C50.919, is paramount for several reasons:
- Reimbursement: Correct coding ensures that healthcare providers receive appropriate reimbursement for the services they provide. Using the right codes is essential for accurate billing and avoiding claim denials.
- Data Analysis and Epidemiology: ICD-10-CM codes are used for statistical tracking of diseases. Accurate coding contributes to reliable data on breast cancer incidence, prevalence, and trends, which is vital for public health planning and research.
- Clinical Decision Making: While coding is primarily for administrative and statistical purposes, accurate diagnosis coding reflects the clinical picture of the patient. This information can be used in broader clinical data analysis to improve patient care pathways and outcomes.
In conclusion, ICD-10-CM code C50.919, “Malignant neoplasm of unspecified site of unspecified female breast,” is a crucial code in the classification of breast cancer. Understanding its meaning, application, and related terms is essential for healthcare professionals involved in diagnosis, coding, billing, and data analysis related to breast cancer. Accurate and consistent use of this and other breast cancer ICD-10 diagnosis codes contributes significantly to effective healthcare administration, research, and ultimately, improved patient care.
