In simple words: This code refers to problems with hormone-producing organs or metabolism after a medical procedure, that are not covered by other codes.

This code encompasses complications and disorders affecting the endocrine system that arise following a procedure, but are not classified under other, more specific codes within the ICD-10-CM.

Example 1: A patient develops hypothyroidism following a thyroidectomy. This would be coded as E89.0., A patient experiences adrenal insufficiency after removal of an adrenal gland tumor. This would be coded as E89.1., A patient develops persistent hyperparathyroidism following a parathyroidectomy. This would be coded as E89.89, as it's not otherwise specified in the E89 subcategory.

Detailed documentation of the postprocedural endocrine or metabolic disorder, including the type of procedure performed, the affected organ or system, the specific signs and symptoms, and any diagnostic testing or treatment provided, is essential for accurate coding.

** All neoplasms, whether functionally active or not, are classified in Chapter 2. Specific codes within Chapter 4 (E00-E89) may be used as additional codes to indicate functional activity or dysfunction associated with neoplasms.
