2025 ICD-10-CM code C50
(Active) Effective Date: N/A Neoplasms - Malignant neoplasms of breast 2 Neoplasms Feed
Malignant neoplasm of breast. Includes connective tissue of breast, Paget's disease of breast, and Paget's disease of nipple.
Medical necessity for treatment of malignant neoplasm of the breast is established by the confirmed diagnosis of malignancy. Treatment is required to prevent further spread and potential mortality.
Clinicians diagnose breast cancer based on patient history, physical examination, and diagnostic procedures such as biopsies, mammograms, ultrasounds, MRIs, and PET scans. Treatment depends on the stage and may include surgery (lumpectomy or mastectomy), chemotherapy, radiation therapy, and targeted therapies.
In simple words: Breast cancer is a disease where cells in the breast grow out of control and form a tumor. This code refers to cancerous tumors in the breast tissue itself, including Paget's disease of the nipple.
Malignant neoplasm of the breast refers to the abnormal, uncontrolled growth of cells in the breast tissue. This includes tumors originating in the connective tissue of the breast, as well as Paget's disease of the breast and nipple.Use additional code to identify estrogen receptor status (Z17.0, Z17.1). Excludes skin of breast (C44.501, C44.511, C44.521, C44.591).
Example 1: A 55-year-old female presents with a palpable lump in her right breast, confirmed as malignant through biopsy.This is coded as C50., A 60-year-old male is diagnosed with Paget's disease of the nipple, which is a form of breast cancer. This would also be coded as C50., A 48-year-old female undergoes a mastectomy for a malignant tumor in her left breast, with subsequent pathology revealing involvement of the connective tissue. This is coded C50.
Documentation should include details of the diagnosis, including location and size of the tumor, histologic type, stage if applicable, estrogen receptor status (documented with Z17.0 or Z17.1), and any associated conditions.
** For more specific coding related to laterality, morphology, or estrogen receptor status, refer to more specific codes under C50. Check documentation guidelines for accurate staging and documentation of receptor status.Refer to iFrameAI for the most up-to-date information regarding coding guidelines and medical billing practices.
