What This Code Means

Overproduction of hormones by the adrenal glands, causing excessive cortisol or other adrenal hormones in the body.

Coding Tips

• •Verify the underlying cause (e.g., adrenal tumor, pituitary disorder) and code separately if documented
• •Distinguish from Cushing's syndrome which may have a more specific code depending on etiology

Clinical Significance

Other adrenocortical overactivity encompasses excess production of adrenal cortical hormones not classified under Cushing syndrome or hyperaldosteronism specifically. This may include isolated cortisol or androgen excess from adrenal hyperplasia or functional adrenal masses that do not meet full Cushing syndrome criteria.

Documentation Requirements

• ✓Document which adrenal hormone is elevated, underlying cause (adrenal hyperplasia, adrenal mass, adrenocorticotropic hormone-independent causes), hormone levels, imaging findings, clinical manifestations, and treatment approach.
