2019 ICD-10-CM Diagnosis Code D09.9

Carcinoma in situ, unspecified

    2016 2017 2018 2019 Billable/Specific Code
  • D09.9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
  • The 2019 edition of ICD-10-CM D09.9 became effective on October 1, 2018.
  • This is the American ICD-10-CM version of D09.9 - other international versions of ICD-10 D09.9 may differ.
The following code(s) above D09.9 contain annotation back-references
Annotation Back-References

  • Code First annotations, or
  • Excludes1 annotations, or
  • Excludes2 annotations, or
  • Includes annotations, or

    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).

  • Cancer in situ
  • Cancer in situ in villous adenoma
  • Carcinoma in situ
  • Carcinoma in situ in villous adenoma
  • Muir-torre syndrome
  • Muir-torrè syndrome
Clinical Information
  • (kar-sin-o-ma in sye-too) cancer that involves only the cells in which it began and that has not spread to neighboring tissues.
  • A group of abnormal cells that remain in the place where they first formed. They have not spread. These abnormal cells may become cancer and spread into nearby normal tissue.
  • A lesion with cytological characteristics associated with invasive carcinoma but the tumor cells are confined to the epithelium of origin, without invasion of the basement membrane.
  • A malignant epithelial neoplasm confined to the epithelial layer and without evidence of further tissue invasion.
  • A malignant epithelial neoplasm which is confined to the epithelial layer without evidence of further tissue invasion.
