ICD-10 Code D29.20 – Benign neoplasm of unspecified testis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D29.20 – Benign neoplasm of unspecified testis
What it is
This code identifies a noncancerous tumor of the testis when the record does not specify the exact testicular site. Use it for benign testicular growths documented without evidence of malignancy.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include a painless testicular mass, swelling, or an incidental imaging finding, but diagnosis should be supported by the provider’s assessment.
When to use this code
Use D29.20 when the provider documents a benign neoplasm of the testis and does not name the side or a more specific testicular structure. It also fits cases where pathology or imaging confirms a benign testicular tumor, but the note remains nonspecific. If the record later identifies a more exact site, code that specific diagnosis instead.
Do not use for
Do not use this code for malignant testicular tumors, germ cell cancer, or unspecified scrotal masses without a documented benign neoplasm. Check documentation if the lesion is described only as cystic, inflammatory, or uncertain.
Coding tip
Query the provider when the chart says “testicular mass” but does not clearly state benign neoplasm or specify the testis.
