What This Code Means
E65 is the ICD-10-CM diagnosis code for localized adiposity. Excessive fat deposits in specific areas of the body, such as the abdomen or neck. E65 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering overweight, obesity and other hyperalimentation (e65-e68).
E65 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.
This code is for localized fat accumulation, not generalized obesity.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for E65 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
