Carcinoma in situ of breast

2016 2017 2018 2019 2020 2021 2022 2023 Non-Billable/Non-Specific Code

• D05 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
• The 2023 edition of ICD-10-CM D05 became effective on October 1, 2022.
• This is the American ICD-10-CM version of D05 - other international versions of ICD-10 D05 may differ.

• Abnormal cells that are confined to the ducts or lobules in the breast. There are two forms, called ductal carcinoma in situ (dcis) and lobular carcinoma in situ (lcis).
• Stage 0 includes: tis, n0, m0. Tis: carcinoma in situ. N0: no regional lymph node metastasis. M0: no distant metastasis. (ajcc 6th and 7th eds.)
• Stage 0 includes: tis, n0, m0. Tis: carcinoma in situ. N0: no regional lymph node metastasis. M0: no distant metastasis. (ajcc 6th ed.)
• There are 2 types of stage 0 breast carcinoma in situ: ductal carcinoma in situ (dcis) and lobular carcinoma in situ (lcis). Dcis is a noninvasive condition in which abnormal cells are found in the lining of a breast duct (a tube that carries milk to the nipple). The abnormal cells have not spread outside the duct to other tissues in the breast. In some cases, dcis may become invasive cancer and spread to other tissues, although it is not known how to predict which lesions will become invasive cancer. Lcis is a condition in which abnormal cells are found in the lobules (small sections of tissue involved with making milk) of the breast. This condition seldom becomes invasive cancer; however, having lcis in one breast increases the risk of developing breast cancer in either breast.
