C50.5 - Malignant neoplasm of lower-outer quadrant of breast

Version 2023
ICD-10:C50.5
Short Description:Malignant neoplasm of lower-outer quadrant of breast
Long Description:Malignant neoplasm of lower-outer quadrant of breast
Status: Not Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Neoplasms (C00–D48)
    • Malignant neoplasms of breast (C50)
      • Malignant neoplasm of breast (C50)

C50.5 is a non-specific and non-billable ICD-10 code code, consider using a code with a higher level of specificity for a diagnosis of malignant neoplasm of lower-outer quadrant of breast. The code is not specific and is NOT valid for the year 2023 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic breast (connective tissue) (glandular tissue) (soft parts) lower-outer quadrant .

Specific Coding for Malignant neoplasm of lower-outer quadrant of breast

Non-specific codes like C50.5 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for malignant neoplasm of lower-outer quadrant of breast:

  • NON-BILLABLE CODE - C50.51 for Malignant neoplasm of lower-outer quadrant of breast, female
  • BILLABLE CODE - Use C50.511 for Malignant neoplasm of lower-outer quadrant of right female breast
  • BILLABLE CODE - Use C50.512 for Malignant neoplasm of lower-outer quadrant of left female breast
  • BILLABLE CODE - Use C50.519 for Malignant neoplasm of lower-outer quadrant of unspecified female breast
  • NON-BILLABLE CODE - C50.52 for Malignant neoplasm of lower-outer quadrant of breast, male
  • BILLABLE CODE - Use C50.521 for Malignant neoplasm of lower-outer quadrant of right male breast
  • BILLABLE CODE - Use C50.522 for Malignant neoplasm of lower-outer quadrant of left male breast
  • BILLABLE CODE - Use C50.529 for Malignant neoplasm of lower-outer quadrant of unspecified male breast

Table of Neoplasms

This code is referenced 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.

Breast Cancer

What is breast cancer?

Breast cancer is a cancer that starts in breast tissue. It happens when cells in the breast change and grow out of control. The cells usually form a tumor.

Sometimes the cancer does not spread any further. This is called "in situ." If the cancer spreads outside the breast, the cancer is called "invasive." It may just spread to nearby tissues and lymph nodes. Or the cancer may metastasize (spread to other parts of the body) through the lymph system or the blood.

Breast cancer is the second most common type of cancer in women in the United States. Rarely, it can also affect men.

What are the types of breast cancer?

There are different types of breast cancer. The types are based on which breast cells turn into cancer. The types include:

What causes breast cancer?

Breast cancer happens when there are changes in the genetic material (DNA). Often, the exact cause of these genetic changes is unknown.

But sometimes these genetic changes are inherited, meaning that you are born with them. Breast cancer that is caused by inherited genetic changes is called hereditary breast cancer.

There are also certain genetic changes that can raise your risk of breast cancer, including changes in the BRCA1 and BRCA2 genes. These two changes also raise your risk of ovarian and other cancers.

Besides genetics, your lifestyle and the environment can affect your risk of breast cancer.

Who is at risk for breast cancer?

The factors that raise your risk of breast cancer include:

What are the signs and symptoms of breast cancer?

The signs and symptoms of breast cancer include:

How is breast cancer diagnosed?

Your health care provider may use many tools to diagnose breast cancer and figure out which type you have:

If these tests show that you have breast cancer, you will have tests that study the cancer cells. These tests help your provider decide which treatment would be best for you. The tests may include:

Another step is staging the cancer. Staging involves doing tests to find out whether the cancer has spread within the breast or to other parts of the body. The tests may include other diagnostic imaging tests and a sentinel lymph node biopsy. This biopsy is done to see whether the cancer has spread to the lymph nodes.

What are the treatments for breast cancer?

Treatments for breast cancer include:

Can breast cancer be prevented?

You may be able to help prevent breast cancer by making healthy lifestyle changes such as:

If you are at high risk, your health care provider may suggest that you take certain medicines to lower the risk. Some women at very high risk may decide to get a mastectomy (of their healthy breasts) to prevent breast cancer.

It's also important to get regular mammograms. They may be able to identify breast cancer in the early stages, when it is easier to treat.
