Unspecified lump in the right breast, upper outer quadrant

This code signifies the presence of an uncharacterized mass or palpable abnormality located specifically in the upper outer quadrant of the patient's right breast. It indicates that further diagnostic workup is required to determine the nature (e.g., benign, malignant, cystic) of the lump.

Use this code when a patient presents with a newly discovered or previously noted lump in the specified breast quadrant, and the clinical documentation does not yet provide sufficient detail for a more specific diagnosis. This is appropriate when initial imaging (e.g., mammogram, ultrasound) has identified a lesion but its definitive characterization is pending or unknown.

• Do not use this code if the documentation specifies the lump's etiology (e.g., cyst, fibroadenoma, malignancy); instead, code to the specific diagnosis.
• Always seek clarification from the provider if the documentation indicates a specific characteristic of the lump that could lead to a more precise code.
• This code is often a temporary diagnosis, pending further diagnostic results (e.g., biopsy, advanced imaging).
