2020 ICD-10-CM Diagnosis Code D05

Carcinoma in situ of breast

    2016 2017 2018 2019 2020 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 2020 edition of ICD-10-CM D05 became effective on October 1, 2019.
  • This is the American ICD-10-CM version of D05 - other international versions of ICD-10 D05 may differ.
Type 1 Excludes
Type 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as D05. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

    Neoplasms

    Note
    • Functional activity
    • All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
    • Morphology [Histology]
    • Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
    • Primary malignant neoplasms overlapping site boundaries
    • A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
    • Malignant neoplasm of ectopic tissue
    • Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).

Clinical Information
  • 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.
