| Code Classification: |
N64.9 is a billable ICD-10 code used to specify a medical diagnosis of disorder of breast, unspecified. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The code is commonly used in ob/gyn medical specialties to specify clinical concepts such as lump in breast and other disorders of the breast.
Unspecified diagnosis codes like N64.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Patient Education
Breast Diseases
Most women experience breast changes at some time. Your age, hormone levels, and medicines you take may cause lumps, bumps, and discharges (fluids that are not breast milk).
If you have a breast lump, pain, discharge or skin irritation, see your health care provider. Minor and serious breast problems have similar symptoms. Although many women fear cancer, most breast problems are not cancer.
Some common breast changes are:
- Fibrocystic breast changes - lumpiness, thickening and swelling, often just before a woman's period
- Cysts - fluid-filled lumps
- Fibroadenomas - solid, round, rubbery lumps that move easily when pushed, occurring most in younger women
- Intraductal papillomas - growths similar to warts near the nipple
- Blocked milk ducts
- Milk production when a woman is not breastfeeding
