ICD Code N63.0

ICD code N63.0 is an unspecified lump in an unspecified breast.

1. Presence of a palpable lump or mass detected in the breast during physical examination

2. Lump is not associated with any specific quadrant or region of the breast

3. No clear clinical features to suggest malignancy or benign etiology

4. No accompanying symptoms such as nipple discharge, skin changes, or pain that would specify a more precise diagnosis

5. Imaging studies (e.g., mammogram, ultrasound) are inconclusive or do not provide further specification

6. Patient history does not indicate prior breast conditions or surgeries that would clarify the nature of the lump

7. The lump cannot be attributed to trauma, infection, or other identifiable causes

8. Documentation is insufficient to assign a more specific diagnosis code for the breast lump
