ICD-10 Code E29.9 – Testicular dysfunction, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E29.9 – Testicular dysfunction, unspecified
What it is
E29.9 identifies a disorder of testicular function when the documentation does not specify the exact type. Use it for a general testicular endocrine or functional problem that is not further defined.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may note abnormal testicular function, infertility concerns, reduced androgen production, or other nonspecific gonadal dysfunction without a clearer diagnosis.
When to use this code
Use E29.9 when the provider documents testicular dysfunction but does not name a specific cause or subtype. It also fits when the chart supports impaired testicular function, yet the documentation remains nonspecific. Check documentation if the note suggests a more precise endocrine disorder.
Do not use for
Do not use this code for clearly documented conditions such as testicular hypofunction, congenital anomalies, or infertility without testicular dysfunction. If the record identifies a more specific diagnosis, code that instead.
Coding tip
Query for specificity whenever possible, because E29.9 is a nonspecific fallback code.
