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 2026, 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.
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
The ICD-10 code section E61 covers deficiencies of various nutrient elements essential for bodily function. These codes are used to identify and document conditions caused by insufficient levels of specific minerals like copper, iron, magnesium, and others.
This section is vital for coding different types of mineral deficiencies, such as E61.0 for copper deficiency, commonly linked to conditions like leukoencephalopathy or myelopathy due to copper deficiency. E61.1 captures various forms of iron deficiency, including non-anemic disorders and symptoms like alopecia or glossitis. Other specific codes address lesser-known deficiencies: magnesium (E61.2), manganese (E61.3), chromium (E61.4), molybdenum (E61.5), and vanadium deficiencies (E61.6). The section also includes codes for multiple nutrient element deficiencies (E61.7) and other specified nutrient shortages (E61.8), encompassing conditions related to minerals like iodine and fluoride. When the specific nutrient is unclear, E61.9 covers unspecified nutrient element deficiencies. Understanding these codes helps medical coders accurately map varied nutrient-related disorders to their correct ICD-10 code for deficiency of nutrient elements.
