What are Left Breast Mass ICD-10-CM Codes?
A left breast mass refers to an abnormal lump, swelling, or growth detected in the left breast tissue. This finding can indicate a variety of conditions, ranging from non-malignant breast disorders like cysts or fibroadenomas to malignant neoplasms requiring urgent attention.
Codes for left breast mass or lumps typically fall under N63.2, the category for unspecified lump in left breast. Here are said codes:
- N63.20 Unspecified lump in the left breast, unspecified quadrant
- N63.21 Unspecified lump in the left breast, upper outer quadrant
- N63.22 Unspecified lump in the left breast, upper inner quadrant
- N63.23 Unspecified lump in the left breast, lower outer quadrant
- N63.24 Unspecified lump in the left breast, lower inner quadrant
- N63.25 Unspecified lump in the left breast, overlapping quadrants
For lump in right breast, refer to codes under N63.1.
