About coding Iodine deficiency
The ICD-10-CM code for Iodine deficiency is E61.8 (Deficiency of other specified nutrient elements).
Within E61, choose E61.8 (Deficiency of other specified nutrient elements) 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.
