About E50

E50 is the ICD-10-CM diagnosis code for vitamin A deficiency. It belongs to block E50-E64 (other nutritional deficiencies) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: E50.0 (with conjunctival xerosis), E50.1 (with Bitot's spot and conjunctival xerosis), E50.2 (with corneal xerosis), E50.3 (with corneal ulceration and xerosis), E50.4 (with keratomalacia), E50.5 (with night blindness), E50.6 (with xerophthalmic scars of cornea), E50.7 (deficiency) and 2 more.

Don't report E50 together with the conditions in its Excludes1 note: sequelae of vitamin A deficiency (E64.1).

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