(2022) How To Code Breast Cancer ICD 10 – List With Codes & Guidelines

Breast cancer ICD 10 coding is made easier with our billing guidelines. This article includes all medical codes you will need to report breast cancer and related specific ICD 10 & 11 codes, such as invasive ductal carcinoma of the breast and breast cancer metastasis.

Read on to get a summary of the necessary codes followed by a further description.

What Is Breast Cancer?

Cancer occurs when mutations happen in the genes that control cell growth. Mutations cause cells to divide and multiply in uncontrolled ways.

Breast cancer is cancer that arises from the cells of the breast. Cancers usually form in lobules or tubes in the breast.

The lobules are the milk-producing glands, and the ducts are the pathways that supply milk from the lobular glands to the nipple. Cancer can also develop in the fatty or fibrous connective tissue of the breast.

Uncontrolled cancer cells can often invade other healthy breast tissues in the body and travel to the lymph nodes in the axilla. When cancer enters the lymph nodes, it has access to the lymphatic channels and can travel to other body parts.

Breast cancer may cause no symptoms in its early stages. The tumor is too small to feel, but mammography will reveal abnormalities in many cases.

The first sign of breast cancer usually palpates a lump in the breast that hasn’t been there before. But not all lumps are cancerous.

Each type of breast cancer may cause a variety of symptoms. Many of these symptoms are similar, but some may vary. Some of the symptoms of breast cancer may include:

A change in the size, shape, or contour of the breast.

A mass or lump may feel as small as a pea.

A lump or thickening in or near the breast or the axilla persists through your menstrual cycle.

A change in the look or feel of the skin on the breast or nipple (dimpled, puckered, scaly, or inflamed).

Redness of the skin on the breast or nipple.

An area that’s distinctly different from any other area on either breast.

A marble-like hardened area under the skin.

A blood-stained or clear fluid discharge from the nipple.

There are many types of breast cancer. Classifications are determined by specific types of cells in the breast affected by cancer.

Most breast cancer is carcinoma. Adenocarcinoma is the most common breast cancer, such as ductal carcinoma in situ (DCIS) and invasive carcinoma.

Other types of breast cancer include angiosarcoma or sarcoma. However, they are not considered breast cancer since they start in different breast cells.

Breast cancer is also classified by the specific type of protein or gene that each cancer can produce.

After a biopsy, breast cancer cells are tested for proteins called estrogen and progesterone receptors and the HER2 gene or protein.

Tumor cells are also scrutinized in the laboratory to find out what grade they are. The specific proteins and tumor grades found help determine the stage of cancer and treatment options.

Several breast cancer treatment options include surgery, chemotherapy, radiation therapy, hormone therapy, immunotherapy, and targeted drug therapy.

Breast Cancer ICD 10 

Breast Cancer ICD 10 code for malignant neoplasm of the breast is C50. 

It can be selected in the ICD 10 book by following these steps. First, it is located in the chapter II, which codes for Neoplasms. It is coded (C00-D49). It can be found in block C50, which codes for Malignant neoplasms of the breast. It has the following categories coded under it: 

 C50.0 – Malignant neoplasm of nipple and areola.

 C50.1 – Malignant neoplasm of the central portion of the breast.

 C50.2 – Malignant neoplasm of the upper inner quadrant of the breast.

 C50.3 – Malignant neoplasm of the lower inner quadrant of the breast.

 C50.4 – Malignant neoplasm of the upper-outer quadrant of the breast.

 C50.5 – Malignant neoplasm of the lower outer quadrant of the breast.

 C50.6 – Malignant neoplasm of axillary tail of breast.

 C50.8 – Malignant neoplasm of overlapping sites of the breast.

 C50.9 – Malignant neoplasm of breast of unspecified site.

Each category is further subdivided based on whether the malignant neoplasm occurs in a male or female. 

For example, the ICD 10 code for Malignant neoplasm of nipple and areola in females is C50.01, while the ICD 10 code for Malignant neoplasm of nipple and areola in males is C50.02.

Likewise, the ICD 10 code for Malignant neoplasm of the lower outer quadrant of the breast is C50.51, while the ICD 10 code for Malignant neoplasm of the lower outer quadrant of the breast in males is C50.52.

Metastatic Breast Cancer ICD 10

Metastatic breast cancer occurs when the breast cancer cells have spread to other parts of the body. 

Accurate sequencing for primary and secondary cancer depends on which site is being treated or focused upon at the current encounter.

For instance, a patient who has primary breast cancer (C50.xx) who is now seen for metastatic bone cancer will have a code for the secondary bone cancer (C79.51) sequenced before a code for the primary breast cancer (C50.xx). 

The general code for secondary malignant neoplasm can be seen from C77-C79. 

Invasive Ductal Carcinoma Breast Cancer ICD 10

Invasive ductal carcinoma breast cancer ICD 10 in situ of the unspecified breast is D05.10

D05.10 is a billable/specific ICD 10 CM code that can be used to indicate a diagnosis for reimbursement purposes.

The 2022 edition of ICD 10 CM D05.10 became effective on October 1, 2021.

It can be found in chapter ii C00-D49 which codes for Neoplasms, in the block D00-D09, which codes for In situ neoplasms, and under the category D05, which codes for carcinoma in situ in the breast.

The Approximate Synonyms include:

  • Cancer of the breast, ductal carcinoma in situ
  • Intraductal carcinoma in situ of the breast

Breast Cancer In Remission ICD 10 

The National Cancer Institute defines remission as:

“A decrease in or disappearance of signs or symptoms of cancer. Partial remission, some but not all signs and symptoms of cancer have disappeared. Complete remission, all signs and symptoms of cancer have disappeared, although cancer still may be in the body.”

Some providers say that aromatase inhibitors and tamoxifen therapy are applied during the complete remission of invasive breast cancer to prevent invasive cancer from recurring or distant metastasis.

However, cancer still may be in the body.

In remission generally is coded as current, as long as there is no contradictory information elsewhere in the record.

Thus, breast cancer in remission will be coded as C50.

Genetic Predisposition To Breast Cancer ICD 10

Genetic predisposition to breast cancer ICD 10 code is Z15.01.

The ICD 11 code for Malignant neoplasms of the breast is (2C60-2C6Z).

The category refers to primary malignant neoplasms of parenchyma, connective, and soft tissue of the breast, including nipple and areola.

It can be found in chapter 02 Neoplasms, under the block Malignant neoplasms, except primary neoplasms of the lymphoid, hematopoietic, central nervous system, or related tissues coded as (2B50-2E2Z). 

Under the category, Malignant neoplasms stated or presumed to be primary, of specified sites, except lymphoid, hematopoietic, central nervous system, or related tissues coded as (2B50-2D3Z). 

Sections/codes include: 

Carcinoma of breast, specialized type (2C60).

Invasive carcinoma of the breast (2C61).

Inflammatory carcinoma of the breast (2C62).
