Postprocedural endocrine and metabolic complications and disorders, not elsewhere classified (E89) ICD-10-CM
The E89 code range covers postprocedural endocrine and metabolic complications and disorders, not elsewhere classified with 23 ICD-10-CM diagnosis codes. 17 of them are billable and valid for claim submission in fiscal year 2027, 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 E89 Code Range
These conditions arise after a procedure and affect the endocrine system or involve metabolic complications.
The codes separate thyroid (E89.0), low insulin (E89.1), parathyroid (E89.2) and pituitary (E89.3) conditions. They also separate ovarian failure (E89.4), reduced testicular function (E89.5) and reduced adrenal function (E89.6). Ovarian failure splits by whether symptoms are present.
Other complications (E89.8) include bleeding, blood or fluid collections in endocrine organs or structures, and low blood sugar. Bleeding and collections split by whether the preceding procedure involved the endocrine system. Low blood sugar separates cases after bariatric procedures from other cases.
FY 2027 changes: The FY 2027 ICD-10-CM update, effective October 1, 2026, added E89.830 and E89.838.
