Malignant neoplasm of penis, part unspecified

This code signifies a primary cancerous tumor originating in the penis, where the specific anatomical location within the organ (e.g., glans, shaft, prepuce) is not documented. It represents an invasive malignant process affecting penile tissue.

This code is appropriate when a definitive diagnosis of penile malignancy is established, but the medical record lacks specificity regarding the exact site of the tumor within the penis. Documentation supporting its use would include pathology reports confirming malignancy and physician notes indicating "penile cancer, site unspecified" or similar.

• Only use this code when the specific anatomical site of the penile malignancy is truly unknown or unstated in the documentation.
• Prioritize more specific codes (e.g., glans penis, shaft of penis) if available in the documentation.
• This code represents a primary malignancy; do not use for metastatic disease to the penis.
