About E27

E27 is the ICD-10-CM diagnosis code for other disorders of adrenal gland. It belongs to block E20-E35 (disorders of other endocrine glands) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: E27.0 (overactivity), E27.1 (insufficiency), E27.2 (crisis), E27.3 (insufficiency), E27.4 (insufficiency), E27.5 (hyperfunction), E27.8 (gland) and E27.9 (unspecified).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
