E27.40 is a billable ICD code used to specify a diagnosis of unspecified adrenocortical insufficiency. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code E274 is used to code Adrenal insufficiency

Adrenal insufficiency is a condition in which the adrenal glands do not produce adequate amounts of steroid hormones, primarily cortisol; but may also include impaired production of aldosterone (a mineralocorticoid), which regulates sodium conservation, potassium secretion, and water retention. Craving for salt or salty foods due to the urinary losses of sodium is common.
