Malig neoplm of lower-outer quadrant of right female breast

This code signifies a primary cancerous tumor located in the lower-outer quadrant of the right breast in a female patient. This specific quadrant refers to the area of the breast inferior and lateral to the nipple. The malignancy originates within the breast tissue itself.

Apply this code when documentation clearly indicates a confirmed diagnosis of primary malignant neoplasm situated in the lower-outer quadrant of the right female breast. This diagnosis is typically established through biopsy and pathology reports. Use this code for initial encounters, active treatment, or surveillance following treatment for this specific cancer.

• Ensure laterality (right breast) and specific quadrant (lower-outer) are explicitly documented.
• Confirm the patient's sex is female, as this code is sex-specific.
• Do not use for metastatic disease; this code is for the primary site.
