Unspecified lump in right breast, subareolar

This code signifies the presence of a palpable, undefined mass located beneath the nipple and areola of the right breast. It indicates that further diagnostic workup is needed to determine the nature of the lump, as its specific characteristics (e.g., benign, malignant, cystic) are not yet known.

This code is appropriate when a clinician identifies a new or existing lump in the subareolar region of the right breast, and the medical record lacks definitive information regarding its etiology or specific characteristics. Documentation supporting its use would include physical exam findings describing a right subareolar mass without further specification, or imaging reports (e.g., mammogram, ultrasound) that identify a lesion in this area but are inconclusive or pending further evaluation.

• Do not use this code if the lump's specific nature (e.g., fibroadenoma, cyst, malignancy) is known; instead, code to the highest level of specificity.
• Always review subsequent documentation for definitive diagnoses that would supersede this unspecified code.
• This code is often a temporary diagnosis while a patient undergoes diagnostic imaging or biopsy.
