Deficiency of other nutrient elements (E61) ICD-10-CM
The E61 code range covers deficiency of other nutrient elements with 11 ICD-10-CM diagnosis codes. 10 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
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 in This Code Range
Definitions from the National Library of Medicine for conditions coded in the E61 range.
Iron Deficiencies
Deficient amounts of iron in the body as a result of blood loss, diets deficient in iron, or an iron uptake or storage disorder.
Magnesium Deficiency
A nutritional condition produced by a deficiency of magnesium in the diet, characterized by anorexia, nausea, vomiting, lethargy, and weakness. Symptoms are paresthesias, muscle cramps, irritability, decreased attention span, and mental confusion, possibly requiring months to appear. Deficiency of body magnesium can exist even when serum values are normal. In addition, magnesium deficiency may be organ-selective, since certain tissues become deficient before others. (Harrison's Principles of Internal Medicine, 12th ed, p1936)
About the E61 Code Range
These conditions involve too little of a nutrient element, such as copper, iron, or magnesium.
The subdivisions name the element: E61.0 for copper, E61.1 for iron, E61.2 for magnesium, E61.3 for manganese, E61.4 for chromium, E61.5 for molybdenum, and E61.6 for vanadium. The remaining subdivisions distinguish deficiencies of multiple elements (E61.7), other specified elements (E61.8), and an unspecified element (E61.9).
