About E04

E04 is the ICD-10-CM diagnosis code for other nontoxic goiter. It belongs to block E00-E07 (disorders of thyroid gland) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: E04.0 (goiter), E04.1 (nodule), E04.2 (goiter), E04.8 (goiter) and E04.9 (unspecified).

Don't report E04 together with the conditions in its Excludes1 note: congenital goiter (NOS) (diffuse) (parenchymatous) (E03.0) and iodine-deficiency related goiter (E00-E02).

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