G
Code: C50.911

Code Name: ICD-10 Code for Malignant neoplasm of unspecified site of right female breast

Block: Malignant neoplasm of unspecified site of right female breast

C50

Use additional code to identify estrogen receptor status (Z17.0, Z17.1)

Includes: connective tissue of breast
Paget's disease of breast
Paget's disease of nipple

Excludes1: skin of breast (C44.501, C44.511, C44.521, C44.591)

Details: Malignant neoplasms of breast (C50-C50.929)

Guidelines: Neoplasms (C00-D49)

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).

Can anyone clarify the correct coding for metastatic disease. We will use breast cancer as the primary diagnosis 174.9. If the patient has metastatic disease to another organ the cells that have metastasized are actually breast cancer cells. So as an example lets say the patient has metastatic disease to the lung. The cells that have metastasized are breast cancer cells and not lung cells so do you use the secondary code 198.81 for breast or do you use the secondary code for 197.0 for lung.... How do you identify where the cancer metastasized to? Have just had a total brain block and can't seem to get this...any help is appreciated.

you would use the secondary lung ca code to show that is the secondary site for the primary malignancy and then use the breast code as the 174.9 or the V10.3 whichever meets to show the primary site.

Thanks so much.. That is what I have been doing for years but recently someone questioned my coding and then in turn had me questioning myself....Thanks again
