Unspecified lump in the left breast, lower inner quadrant

This code signifies the presence of a palpable mass or thickening in the lower inner quadrant of the patient's left breast, where the specific nature or etiology of the lump has not yet been determined through diagnostic workup. It indicates an abnormal finding requiring further investigation to establish a definitive diagnosis.

This code is appropriate for initial encounters when a patient presents with a newly discovered or reported lump in the specified breast quadrant, and diagnostic imaging (e.g., mammogram, ultrasound, MRI) or biopsy results are pending or inconclusive. It should be used when the provider's documentation clearly identifies the lump's location as the left breast, lower inner quadrant, and its specific characteristics remain undiagnosed.

• Do not use this code if a more specific diagnosis (e.g., fibroadenoma, cyst, malignancy) has been established.
• Ensure documentation specifies "left breast" and "lower inner quadrant" for accurate coding.
• Sequence this code as the primary diagnosis when the lump is the reason for the encounter, followed by any relevant signs or symptoms.
