What This Code Means
E36.8 is the ICD-10-CM diagnosis code for other intraoperative complications of endocrine system. Other unexpected complications involving the endocrine system that occur during surgery, not classified elsewhere. E36.8 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering intraoperative complications of endocrine system (e36).
E36.8 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, 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 this code only when the complication doesn't fit into the more specific E36 subcategories (hemorrhage, puncture, etc.).
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for E36.8 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when the complication doesn't fit into the more specific E36 subcategories (hemorrhage, puncture, etc.)
- •Always document the specific nature of the complication and which endocrine organ is involved
