Malig neoplm of upper-outer quadrant of right female breast

This code signifies a primary cancerous tumor located in the upper-outer quadrant of the right breast in a female patient. This specific quadrant is a common site for breast malignancies.

Apply this code when documentation clearly indicates a confirmed diagnosis of a primary malignant neoplasm originating in the upper-outer quadrant of the right female breast. This diagnosis is typically supported by pathology reports from biopsy or surgical excision.

• Ensure laterality (right) and specific quadrant (upper-outer) are explicitly documented.
• Distinguish from secondary malignancies or carcinoma in situ, which have different codes.
• Sequence as the primary diagnosis when it is the reason for the encounter or treatment.
