ICD-10 Code D29.1 – Benign neoplasm of prostate (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D29.1 – Benign neoplasm of prostate
What it is
D29.1 identifies a noncancerous growth in the prostate gland. Use it when documentation clearly states a benign prostate neoplasm, not inflammation or malignancy.
Clinical signs
Clinical features vary; refer to documentation. Patients may have urinary symptoms or an enlarged prostate, but these findings are not specific to this code.
When to use this code
Use D29.1 when the provider documents a benign tumor of the prostate, such as a benign neoplasm or adenoma. It may also apply when pathology confirms a nonmalignant prostatic mass. If the record only notes prostate enlargement or urinary obstruction without a neoplasm, check documentation.
Do not use for
Do not use D29.1 for prostate cancer, prostatitis, or benign prostatic hyperplasia without a documented neoplasm. If the diagnosis is unclear, check documentation.
Coding tip
Code D29.1 only when the record explicitly supports a benign prostate neoplasm.
