Malignant neoplasm of body of penis

This diagnosis code signifies the presence of a cancerous tumor originating in the main shaft of the penis. It indicates a primary malignancy, meaning the cancer began in the penile body rather than spreading there from another site. This condition typically involves abnormal cell growth within the penile tissues.

This code is appropriate for documenting a confirmed diagnosis of primary malignant neoplasm affecting the body of the penis. It should be used when pathology reports or physician documentation clearly specify the location of the malignancy as the penile shaft. Clinical scenarios include initial diagnosis, staging, and treatment planning for this specific cancer.

• Ensure documentation specifies "body of penis" to differentiate from other penile anatomical sites.
• Do not use for secondary malignancies or carcinoma in situ; specific codes exist for those conditions.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, unless a more definitive treatment-related code takes precedence.
