ICD-10 Code E89.5 – Postprocedural Testicular Hypofunction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E89.5 – Postprocedural testicular hypofunction
What it is
E89.5 identifies testicular underfunction that develops after a procedure or surgery. Use it when documentation links reduced testicular function to a prior intervention, not to a congenital or primary endocrine disorder.
Clinical signs
Clinical features may include reduced testosterone production, infertility, decreased libido, or testicular atrophy after treatment. Clinical features vary; refer to documentation.
When to use this code
Use E89.5 when the record states postprocedural hypofunction of the testes, such as after orchiectomy, testicular surgery, or another documented procedure affecting testicular function. You should code it only when the provider clearly connects the condition to the procedure.
If the note describes hypogonadism without a postprocedural cause, check documentation before assigning this code. It may also be used alongside other aftercare or complication codes when the postoperative relationship is documented.
Do not use for
Do not use this code for congenital testicular disorders, primary hypogonadism, or nonspecific endocrine complaints. Do not assume a postoperative cause unless the chart says so.
Coding tip
Look for explicit wording such as “postprocedural” or “following surgery” before assigning E89.5.
