0.000What This Code Means
Early-stage melanoma confined to the skin surface of the breast area, including both the skin and superficial soft tissue.
Coding Tips
- •Specify whether the melanoma is on the breast skin itself versus other chest wall locations
- •Document laterality (right vs. left breast) in the medical record for complete clinical information
Clinical Significance
Melanoma in situ of the breast skin and soft tissue represents early melanocytic malignancy confined to the epidermal layer of the breast skin, without invasion into the dermis. This must be distinguished from breast carcinoma in situ (ductal or lobular), which is an entirely different entity arising from breast glandular tissue. Cutaneous melanoma of the breast skin has the same prognostic implications as melanoma in situ at other truncal sites.
Documentation Requirements
- ✓Biopsy-confirmed melanoma in situ with pathology clearly specifying the breast skin as the site.
- ✓Laterality (right vs.
- ✓left) should be documented.
- ✓The distinction between cutaneous melanoma of the breast skin and breast carcinoma must be explicit in the pathology report.
- ✓Document margin status and surveillance plan.
Commonly Confused Codes
D05.10-D05.92 (carcinoma in situ of breast) are completely different entities arising from breast glandular tissueD03.59 (melanoma in situ of other part of trunk) covers other trunk locationsC43.52 (invasive melanoma of breast skin) indicates dermal invasionC50 series codes are for breast parenchymal malignancies.
