What This Code Means
E89.5 is the ICD-10-CM diagnosis code for postprocedural testicular hypofunction. Reduced testosterone production and testicular function that develops after a surgical procedure or medical treatment. E89.5 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering postprocedural endocrine and metabolic complications and disorders, not elsewhere classified (e89).
E89.5 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Link to the specific procedure causing the hypofunction (surgery, chemotherapy, or radiation).
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for E89.5 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Link to the specific procedure causing the hypofunction (surgery, chemotherapy, or radiation)
- •Document testosterone levels if available to support the diagnosis
