ICD-10 Code C50.8

Malignant neoplasm of overlapping sites of breast

Version 2019 Non-Billable Code Neoplasm Malignant Primary
ICD-10: C50.8
Short Description:Malignant neoplasm of overlapping sites of breast
Long Description:Malignant neoplasm of overlapping sites of breast

Not Valid for Submission

ICD-10 C50.8 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of malignant neoplasm of overlapping sites of breast. The code is NOT valid for the year 2019 for the submission of HIPAA-covered transactions.

Consider the following ICD-10 codes with a higher level of specificity:

  • C50.81 - Malignant neoplasm of overlapping sites of breast, female
  • C50.811 - Malignant neoplasm of overlapping sites of right female breast
  • C50.812 - Malignant neoplasm of overlapping sites of left female breast
  • C50.819 - Malignant neoplasm of overlapping sites of unspecified female breast
  • C50.82 - Malignant neoplasm of overlapping sites of breast, male
  • C50.821 - Malignant neoplasm of overlapping sites of right male breast
  • C50.822 - Malignant neoplasm of overlapping sites of left male breast
  • C50.829 - Malignant neoplasm of overlapping sites of unspecified male breast

Code Classification

  • Neoplasms (C00–D48)
    • Malignant neoplasms of breast (C50)
      • Malignant neoplasm of breast (C50)

Table of Neoplasms

The code C50.8 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

The Tabular must be reviewed for the complete diagnosis code.

Information for Patients


Breast Cancer

Breast cancer affects one in eight women during their lives. No one knows why some women get breast cancer, but there are many risk factors. Risks that you cannot change include

  • Age - the risk rises as you get older
  • Genes - two genes, BRCA1 and BRCA2, greatly increase the risk. Women who have family members with breast or ovarian cancer may wish to be tested for the genes.
  • Personal factors - beginning periods before age 12 or going through menopause after age 55

Other risks include obesity, using hormone replacement therapy (also called menopausal hormone therapy), taking birth control pills, drinking alcohol, not having children or having your first child after age 35, and having dense breasts.

Symptoms of breast cancer may include a lump in the breast, a change in size or shape of the breast, and discharge from a nipple. Breast self-exams and mammography can help find breast cancer early, when it is most treatable. One possible treatment is surgery. It could be a lumpectomy or a mastectomy. Other treatments include radiation therapy, chemotherapy, hormone therapy, and targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells.

Men can have breast cancer, too, but it is rare.

ICD-10 Footnotes

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
