About coding hemosiderosis
The ICD-10-CM code for hemosiderosis is E83.19 (Other disorders of iron metabolism). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on E83.19.
Within E83.1, choose E83.19 (Other disorders of iron metabolism) only when documentation doesn't support a more specific option: disorder of iron metabolism, unspecified (E83.10) and hemochromatosis (E83.11).
Use an additional code, if applicable, for idiopathic pulmonary hemosiderosis (J84.03).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
