ICD-10 Code D29.0 – Benign neoplasm of penis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D29.0 – Benign neoplasm of penis
What it is
D29.0 identifies a noncancerous growth arising in the penis. Use it when the record documents a benign neoplasm and not a malignant or uncertain lesion.
Clinical signs
Findings may include a localized penile mass, plaque, or lump that is described as benign on exam or pathology. Clinical features vary; refer to documentation.
When to use this code
Use D29.0 when the provider documents a benign tumor of the penis, whether based on clinical assessment, imaging, or biopsy. It also fits cases with a pathology report confirming benign neoplasm. If the note only says “lesion” or “growth,” you should check documentation for the exact diagnosis.
Do not use for
Do not use this code for malignant penile tumors, dysplasia, or lesions of uncertain behavior. Also avoid it when the diagnosis is nonspecific and the record does not confirm a benign neoplasm.
Coding tip
Code from the final documented diagnosis; if pathology is available, it should support the benign nature of the lesion.
