About coding nutrient element deficiency
The ICD-10-CM code for nutrient element deficiency is E61.9 (Deficiency of nutrient element, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on E61.9.
Within E61, choose E61.9 (Deficiency of nutrient element, unspecified) only when documentation doesn't support a more specific option: copper deficiency (E61.0), iron deficiency (E61.1), magnesium deficiency (E61.2), manganese deficiency (E61.3), chromium deficiency (E61.4), Molybdenum deficiency (E61.5), Vanadium deficiency (E61.6), deficiency of multiple nutrient elements (E61.7) and 1 more.
Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
