Unspecified dysplasia of prostate

This code describes an abnormal, but not yet cancerous, cellular development within the prostate gland where the specific type or grade of dysplasia has not been determined. It indicates a precancerous condition or an atypical cellular change requiring further investigation.

Use this code when documentation indicates prostatic dysplasia without further specification of its grade (e.g., low-grade, high-grade) or type. This often occurs when initial biopsy results show atypical cells, but a definitive diagnosis of a specific dysplasia or malignancy is pending or not yet established.

• Do not use this code if the specific grade of prostatic dysplasia (e.g., low-grade, high-grade) is documented; use the more specific codes in the N42.3- series.
• This code should not be used for benign prostatic hyperplasia (BPH) or prostate cancer.
• Ensure documentation clearly states "dysplasia" or "atypical cells concerning for dysplasia" of the prostate without further specificity.
