Asymmetric breast tissue is usually benign and secondary to variations in normal breast tissue, postoperative change, or hormone replacement therapy. However, an asymmetric area may indicate a developing mass or an underlying cancer.
N64. 89 - Other specified disorders of breast. ICD-10-CM.
For example, Z12. 31 (Encounter for screening mammogram for malignant neoplasm of breast) is the correct code to use when you are ordering a routine mammogram for a patient.
Significant breast asymmetry has several possible causes: it may be linked to a breast disease, a developmental problem, a hormonal problem, an unknown syndrome, an injury or periods of significant bodily change such as pregnancy or breastfeeding. One of the diseases linked to breast asymmetry is breast cancer.
Other specified disorders of breast N64. 89 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 N64. 89 became effective on October 1, 2021.
A mammogram is an X-ray of the breast, which can test for any abnormalities, including lumps. A mammogram might reveal that the breasts have different densities. This is referred to as breast asymmetry or focal asymmetry. Focal asymmetry does not always mean that breasts look or feel any different.
Z12. 31 (Encounter for screening mammogram for malignant neoplasm of breast) is reported for screening mammograms while Z12. 39 (Encounter for other screening for malignant neoplasm of breast) has been established for reporting screening studies for breast cancer outside the scope of mammograms.
A screening colonoscopy should be reported with the following International Classification of Diseases, 10th edition (ICD-10) codes: Z12. 11: Encounter for screening for malignant neoplasm of the colon. Z80. 0: Family history of malignant neoplasm of digestive organs.
ICD-10 code R92. 8 for Other abnormal and inconclusive findings on diagnostic imaging of breast is a medical classification as listed by WHO under the range - Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified .
The likelihood of malignancy with focal asymmetry is less than 1%. Follow-up procedures will, to some degree, depend upon whether or not this is a first or subsequent screening. If there are previous mammograms and the focal asymmetry seems to be stable, then a radiologist will consider this mass to be benign.
When age at menopause was included in the model for the subgroup of post-menopausal women, absolute breast fluctuating asymmetry (FA) and relative breast FA remained significant effects. Conclusion: Breast asymmetry was greater in healthy women who later developed breast cancer than in women who did not.
Prepubescent injury: Injury to breast tissue before it has fully developed can lead to breast asymmetry. Trauma, infection, or radiation to one side of the chest are possible injuries that might lead to asymmetric breast growth.
A galactocele (also: lacteal cyst or milk cyst) is a retention cyst containing milk or a milky substance that is usually located in the mammary glands. It is caused by a protein plug that blocks off the outlet. It is seen in lactating women on cessation of lactation. Once lactation has ended the cyst should resolve on its own without intervention.
Inclusion Terms are a list of concepts for which a specific code is used. The list of Inclusion Terms is useful for determining the correct code in some cases, but the list is not necessarily exhaustive.

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code N64.89 and a single ICD9 code, 611.89 is an approximate match for comparison and conversion purposes.
