ICD-10 Code E29 – Testicular dysfunction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E29 – Testicular dysfunction
What it is
E29 identifies disorders of testicular function, including problems with hormone production or other testicular dysfunction. Use it when the record documents impaired testicular activity rather than a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may note hypogonadism, infertility, reduced secondary sexual characteristics, or abnormal testicular hormone function.
When to use this code
Use E29 when the provider documents testicular dysfunction, testicular hypofunction, or a similar nonspecific disorder of testicular function. It is appropriate when the chart does not identify a more precise cause or subtype. Check documentation if the note only describes symptoms without a confirmed diagnosis.
Do not use for
Do not use E29 for infertility alone, sexual dysfunction, or conditions clearly due to another endocrine disorder. If the record specifies a different diagnosis, code that condition instead.
Coding tip
Look for the provider’s exact wording and code the most specific testicular disorder documented, not just the presenting complaint.
