Other vitamin deficiencies (E56)
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.
Instructional Notations
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.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
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
