Malig neoplm of upper-inner quadrant of right female breast

This code signifies a primary cancerous tumor located in the upper-inner quadrant of the right breast in a female patient. It indicates the specific anatomical site and laterality of the malignancy.

Apply this code when documentation clearly states a primary malignant neoplasm originating in the upper-inner quadrant of the right breast. This is typically supported by pathology reports, imaging findings (mammogram, MRI), and physician's notes confirming the tumor's location.

• Ensure the documentation specifies "primary" malignancy; secondary or metastatic lesions to the breast are coded differently.
• Verify the laterality (right) and specific quadrant (upper-inner) are explicitly stated to avoid miscoding.
• Do not use this code for male breast cancer; specific codes exist for male breast malignancies.
