The medical field relies on precise diagnostic codes, and within the ICD-10-CM system, diagnosis code C50.111 holds significant specificity. This code is designated for “Malignant neoplasm of central portion of right female breast.” It’s crucial for medical professionals, insurance providers, and healthcare systems to accurately classify and manage cases of breast cancer.
Specifically, C50.111 is a billable and specific code, meaning it is recognized for reimbursement purposes and provides a detailed diagnosis. The 2025 edition of ICD-10-CM, which became effective on October 1, 2024, includes this code. It’s important to note that this is the American ICD-10-CM version, and international versions might have variations.
This diagnosis code, C50.111, is exclusively applicable to female patients. It clearly indicates a malignant neoplasm, commonly known as cancer, located in the central portion of the right breast. Understanding the terminology is key: “malignant neoplasm” signifies a cancerous tumor, and “central portion” specifies the tumor’s location within the breast.
Several approximate synonyms help clarify the meaning of Diagnosis C50.111. These include:
- Cancer of female breast, right central portion
- Female breast infiltrating ductal carcinoma, right central
- Female breast infiltrating lobular carcinoma, right central
- Infiltrating ductal carcinoma of central portion of right female breast
- Infiltrating lobular carcinoma of central portion of right female breast
- Primary malignant neoplasm of central portion of female right breast
The code C50.111 has a consistent code history, remaining unchanged from 2016 through the 2025 editions of ICD-10-CM. This stability reflects the established and consistent nature of this diagnostic category within the medical coding system.
To further understand C50.111, it’s helpful to look at adjacent ICD-10-CM codes. These include codes for malignant neoplasms in other locations of the breast, such as the nipple and areola (C50.01), and other central portions of the breast (C50.112 for the left breast, C50.119 for unspecified). This context highlights the precise anatomical specificity within the ICD-10-CM coding system.
In conclusion, diagnosis code C50.111 is a critical tool for accurately documenting and classifying cases of malignant neoplasms in the central portion of the right female breast. Its specificity and consistent application within the ICD-10-CM system ensure precise medical record-keeping, facilitate appropriate treatment planning, and enable accurate data analysis for research and public health purposes. For claims with a date of service on or after October 1, 2015, the use of ICD-10-CM codes like C50.111 is mandatory.
