ICD-10 Code D29.22 – Benign neoplasm of left testis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D29.22 – Benign neoplasm of left testis
What it is
D29.22 identifies a noncancerous growth in the left testis. Use it when documentation clearly states a benign testicular neoplasm on the left side.
Clinical signs
Clinical features vary; refer to documentation. Findings may include a testicular mass or swelling, but diagnosis should be supported by the provider’s assessment and side-specific notation.
When to use this code
Use this code when the record documents a benign tumor of the left testis, including pathology or specialist assessment confirming nonmalignant behavior. It is appropriate for encounters focused on evaluation, follow-up, or management of that left-sided lesion.
Do not use for
Do not use D29.22 for malignant testicular tumors, unspecified testicular masses, or lesions in the right testis. Check documentation if the side or behavior is not clearly stated.
Coding tip
Verify both laterality and benign behavior in the note before assigning D29.22.
