ICD-10 Code E89.6 – Postprocedural adrenocortical (-medullary) hypofunction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E89.6 – Postprocedural adrenocortical (-medullary) hypofunction
What it is
This code identifies decreased adrenal cortex or medulla function that develops after a procedure, usually surgery. Use it when documentation links the hormonal deficiency to the postprocedural state.
Clinical signs
Clinical features vary; refer to documentation. Findings may include symptoms of adrenal insufficiency, but the record should show that the hypofunction is postprocedural rather than due to another cause.
When to use this code
Use E89.6 when the provider documents adrenocortical or adrenomedullary hypofunction as a complication of a prior procedure. It may apply after adrenal surgery or other interventions affecting adrenal function. Code it only when the postoperative relationship is clear in the chart.
Do not use for
Do not use this code for primary adrenal disease, congenital adrenal disorders, or unspecified fatigue without documented adrenal hypofunction. Check documentation if the cause is not explicitly postprocedural.
Coding tip
Confirm the procedure link and the exact adrenal term used in the note before assigning E89.6.
