Oth abn and inconclusive findings on dx imaging of breast

This code signifies an abnormal or inconclusive finding detected during a diagnostic imaging study of the breast (e.g., mammogram, ultrasound, MRI) that does not have a more specific ICD-10-CM code. These findings are not definitively benign or malignant and require further investigation or monitoring.

Use this code when imaging reports indicate a finding such as an ill-defined mass, architectural distortion without a clear mass, or an indeterminate lesion that cannot be classified with a more specific code. Documentation should clearly state an abnormal or inconclusive imaging result that warrants further workup or follow-up.

• Do not use this code if a more specific diagnosis, such as a benign neoplasm or a specific type of cyst, is identified.
• Always sequence this code after any definitive diagnosis if one is eventually established.
• Ensure the imaging report explicitly states an "abnormal" or "inconclusive" finding without a more precise characterization.
