ICD-10 Code D29.30 – Benign neoplasm of unspecified epididymis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D29.30 – Benign neoplasm of unspecified epididymis
What it is
D29.30 identifies a noncancerous growth arising in the epididymis when the exact side is not documented. Use it for a benign mass or tumor of epididymal tissue, not for malignant disease.
Clinical signs
Clinical features vary; refer to documentation. Patients may have a palpable scrotal or paratesticular mass, local swelling, or incidental imaging findings, but the diagnosis should be supported by clinician assessment.
When to use this code
Use this code when the record clearly states a benign neoplasm of the epididymis and does not specify right or left side. It is appropriate for pathology, imaging, or operative documentation confirming a benign epididymal lesion. If the site is documented as one side, choose the laterality-specific code instead.
Do not use for
Do not use this code for malignant neoplasms, inflammatory epididymal conditions, or nonspecific scrotal masses without a confirmed benign epididymal diagnosis. Check documentation if the lesion is testicular or paratesticular rather than epididymal.
Coding tip
Confirm both benign behavior and epididymal origin before assigning D29.30.
