ICD-10 Code D29.31 – Benign neoplasm of right epididymis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D29.31 – Benign neoplasm of right epididymis
What it is
D29.31 identifies a noncancerous growth arising in the right epididymis, the coiled tube behind the testis. Use it when documentation clearly states a benign epididymal neoplasm on the right side.
Clinical signs
Clinical features vary; refer to documentation. Patients may have a painless scrotal mass, local fullness, or an incidental imaging finding, but diagnosis should be supported by a clinician’s record.
When to use this code
Use this code when the provider documents a benign tumor of the right epididymis, including cases confirmed by imaging, pathology, or operative findings. It also fits when the record specifies a right-sided epididymal neoplasm and clearly states it is benign. If laterality or benign nature is unclear, check documentation.
Do not use for
Do not use D29.31 for malignant epididymal tumors, inflammatory epididymal disease, or nonspecific scrotal complaints. If the lesion is not documented as benign or right-sided, check documentation.
Coding tip
Verify both laterality and benign behavior in the provider’s note before assigning D29.31.
