Other vitamin deficiencies (E56) ICD-10-CM
The E56 code range covers other vitamin deficiencies with 5 ICD-10-CM diagnosis codes. 4 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Definitions from the National Library of Medicine for conditions coded in the E56 range.
Vitamin E Deficiency
A nutritional condition produced by a deficiency of VITAMIN E in the diet, characterized by posterior column and spinocerebellar tract abnormalities, areflexia, ophthalmoplegia, and disturbances of gait, proprioception, and vibration. In premature infants vitamin E deficiency is associated with hemolytic anemia, thrombocytosis, edema, intraventricular hemorrhage, and increasing risk of retrolental fibroplasia and bronchopulmonary dysplasia. An apparent inborn error of vitamin E metabolism, named familial isolated vitamin E deficiency, has recently been identified. (Cecil Textbook of Medicine, 19th ed, p1181)
Vitamin K Deficiency
A nutritional condition produced by a deficiency of VITAMIN K in the diet, characterized by an increased tendency to hemorrhage (HEMORRHAGIC DISORDERS). Such bleeding episodes may be particularly severe in newborn infants. (From Cecil Textbook of Medicine, 19th ed, p1182)
Vitamin K Deficiency Bleeding
Hemorrhage caused by vitamin K deficiency.
Vitamins
Organic substances that are required in small amounts for maintenance and growth, but which cannot be manufactured by the human body.
About the E56 Code Range
ICD-10 codes E56 through E56.9 are used to identify various specific and unspecified vitamin deficiencies beyond the common ones like vitamins A, D, or B-complex. These codes help document conditions linked to insufficient levels of vitamins such as E and K, as well as other less commonly coded vitamin shortages.
For example, E56.0 is assigned for a deficiency of vitamin E, which may present with symptoms like spinocerebellar ataxia, sensory polyneuropathy, or dementia caused by nutritional lack of vitamin E. Common synonyms including "Vitamin E deficiency" or "Nutritional ataxic neuropathy" connect these clinical presentations directly to this code. Similarly, E56.1 covers vitamin K deficiency, critical for blood clotting, with terms like "Vitamin K1 below reference range" or simply "Vitamin K deficiency" linked to this diagnosis. The code E56.8 captures deficiencies of other less common vitamins, such as "Vitamin P deficiency," while E56.9 is used when the specific vitamin deficiency isn’t determined but symptoms like acquired ataxia or encephalopathy due to vitamin insufficiency are present. These ICD-10 codes facilitate precise recording and billing for nutritional disorders related to vitamin deficits beyond the more common types, aiding both healthcare providers and medical coders in accurate diagnosis classification.
