About E34

E34 is the ICD-10-CM diagnosis code for other endocrine disorders. 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: E34.0 (syndrome), E34.1 (hormones), E34.2 (classified), E34.3 (disorder), E34.4 (stature), E34.5 (syndrome), E34.8 (disorders) and E34.9 (unspecified).

Don't report E34 together with the conditions in its Excludes1 note: pseudohypoparathyroidism (E20.1).

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