Other hemochromatosis

This code represents forms of hemochromatosis that are not hereditary (primary) or secondary to chronic blood transfusions or other specified causes. It encompasses various less common or atypical presentations of iron overload disorders that lead to tissue damage. This includes conditions like neonatal hemochromatosis or aceruloplasminemia, where iron accumulation is a primary feature.

Use this code when documentation specifies a diagnosis of hemochromatosis that does not fit the criteria for hereditary hemochromatosis (e.g., C28.0) or secondary hemochromatosis due to transfusions (e.g., D63.0). This code is appropriate for cases where the etiology of iron overload is clearly identified as a form of hemochromatosis but falls outside the more common categories. Supporting documentation should clearly state the specific type of hemochromatosis or indicate that it is "other specified" or "atypical."

• Do not use this code for hereditary hemochromatosis; refer to codes in the E83.11- series for specific genetic types.
• Distinguish carefully between hemochromatosis and hemosiderosis; this code is specifically for hemochromatosis.
• Always review the medical record for the specific type of hemochromatosis to ensure the most precise code is selected.
