Intraoperative complications of endocrine system (E36) ICD-10-CM
The E36 code range covers intraoperative complications of endocrine system with 8 ICD-10-CM diagnosis codes. 5 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the E36 Code Range
ICD-10 codes starting with E36 are used specifically to identify complications that occur during surgery involving the endocrine system. These codes help document issues such as bleeding, accidental injury, or other problems that arise while operating on endocrine organs.
The E36 code range covers various intraoperative problems in endocrine procedures. For instance, E36.0, E36.01, and E36.02 describe hemorrhages or hematomas complicating surgery on endocrine structures, whether during endocrine-specific or other types of operations. Codes E36.1, E36.11, and E36.12 cover accidental punctures or lacerations that may occur during these procedures. The E36.8 category accounts for other less common intraoperative complications affecting the endocrine system. These codes assist healthcare providers and coders in accurately reporting surgical risks and complications related to glands and organs such as the thyroid, adrenal glands, or pancreas during medical procedures, supporting precise clinical documentation and billing for endocrine system surgeries.
