Personal history of prostatic dysplasia

This code indicates a patient's past medical history of prostatic dysplasia, which refers to abnormal, but not yet cancerous, cell growth within the prostate gland. It signifies that the patient has previously been diagnosed with and treated for or monitored for this precancerous condition.

Use this code when documenting a patient's history of prostatic intraepithelial neoplasia (PIN) or other forms of prostatic dysplasia, particularly when it's relevant to ongoing care, screening, or risk assessment. This code is appropriate for follow-up visits after a diagnosis of dysplasia has been made and managed.

• Do not use this code if the patient has a current diagnosis of prostatic dysplasia; instead, use the appropriate code from the N42 category.
• Ensure to differentiate between a history of dysplasia and a history of malignant prostate cancer, as there is an Excludes1 note for the latter.
• This code is typically a secondary diagnosis, supporting the medical necessity of continued monitoring or specific preventive measures.
