How to code icd 9 codes breast cancer

Basic of icd 9 codes breast cancer

Breast cancer is a malignant tumor in the breast. Breast cancer may metastasize to almost any organ in the body but most commonly involves the lung, liver, bone, lymph nodes and skin. We are here to learn about icd 9 codes breast cancer.

The breast is composed of three types of tissues: glandular, fibrous, and fatty. Glandular tissues contains milk-producing  glands/lobules and the milk ducts; the fibrous and fatty tissues together are referred to as stromal tissue. The breast is also made up of lymphatic tissue that removes cellular fluids and waste. There are different types of tumors that can develop in the different areas of the breast. Often the name of the “cell type” identifies the point of origin. Common types of breast malignancy include, but are not limited to: 

Infiltrating/invasive ductal carcinoma: This is an invasive malignancy with its origin in the milk ducts. The abnormal cells penetrate the wall of the milk ducts and the fatty tissue in the breast. This type of breast cancer is the most common of the invasive types accounting for 80% of breast cancer cases.

Lobular carcinoma in situ: A non-invasive type malignancy, with abnormal increase in the number of cells in the milk glands/lobules
Ductal carcinoma in situ: This is the most common non-invasive breast malignancy. It is found in the ducts of the breast and is most often detected as a microcalcification on mammography
Infiltrating lobular carcinoma: This is an invasive malignancy with its origin in the milk glands/lobules Other less common cell types include, but are not limited to medullary carcinoma, tubular carcinoma, Paget’s disease, and Phylloides tumor.

ICD 10 codes Breast cancer

C50.019 (174.0) - Malignant neoplasm of nipple and areola, unspecified female breast
C50.919 (174.9) - Malignant neoplasm of unspecified breast of unspecified female breast
C50.029 (175.0) - Malignant neoplasm of nipple and areola, unspecified male breast
C50.929 (175.9) - Malignant neoplasm of unspecified breast of unspecified male breast
D05.90 (233.0) -  Unspecified type of carcinoma in situ of unspecified breast

These are most common icd 9 and icd 10 codes breast cancer.

One of the most common sites of breast disease is the upper, outer quadrant of the breast. 50 percent of breast disease occurs in this quadrant. This is followed by 18 percent in the nipple; 15 percent in the upper, inner quadrant; 6 percent in the lower, inner  quadrant; and 1 percent in the lower, outer quadrant. The remaining percentage (10 percent) is distributed in the axillary tail and in  multiple sites.

Documentation required for Coding Breast Cancer

When the history is taken, special note should be made of breast cancer risk factors. These include a personal or family history of breast cancer, delayed childbearing and personal history of benign breast disease. When symptoms are present, the most common one is a nontender, firm or hard lump with poorly delineated margins. Less common symptoms include pain; nipple discharge; skin or nipple retraction; erosion, enlargement, or itching of the nipple. Physical evaluation should include assessment of the local lesion and a search for evidence of metastases in regional lymph nodes (axillary, internal mammary) or distant sites. The precise location and size of the abnormality should be noted on a drawing of the breast.

Diagnostic Work-up:• Laboratory Results: In disseminated cancer, the sedimentation rate may be consistently elevated. Hypercalcemia may be present. Elevation of serum alkaline phosphatase may be an indication of liver or bone metastasis. Carcinoembryonic antigen (CEA) may be a marker for recurrent breast cancer.

X-ray Findings: suspicious area(s) on a mammogram• Biopsy: An unequivocal histologic diagnosis of malignancy from the examination of biopsy tissue must be made before treatment is undertaken. There are several types of biopsies: needle core, fine needle aspiration, stereotactic, incisional and excisional.
