What This Code Means

E29.9 is the ICD-10-CM diagnosis code for testicular dysfunction, unspecified. A general diagnosis of testicular dysfunction when the specific type or cause has not been determined or documented. E29.9 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering disorders of other endocrine glands (e20-e35).

E29.9 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.

Use only when the specific type of testicular dysfunction cannot be determined from documentation.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for E29.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
