Dysplasia of prostate

This code signifies abnormal cellular development within the prostate gland, specifically prostatic dysplasia. It represents a precancerous condition where prostatic cells exhibit atypical changes but have not yet invaded surrounding tissue. This is distinct from benign prostatic hyperplasia (BPH) or prostate cancer.

Apply this code when documentation explicitly states "prostatic dysplasia," "atypical adenomatous hyperplasia (AAH)," or "prostatic intraepithelial neoplasia (PIN)" without evidence of malignancy. This diagnosis is typically made following a prostate biopsy.

• Do not use this code if a definitive diagnosis of prostate cancer (malignant neoplasm) is made; instead, code to the appropriate malignancy code.
• Distinguish carefully from benign prostatic hyperplasia (BPH), which involves glandular enlargement but not necessarily dysplastic changes.
• Ensure the pathology report clearly indicates dysplasia and not just inflammation or reactive atypia.
