What This Code Means

A metabolic disorder affecting iron levels in the body where the specific type or cause has not been identified.

Coding Tips

•This is a non-specific code; attempt to identify whether the disorder is hemochromatosis, iron deficiency, or another specific iron metabolism condition
•Review for more specific iron metabolism codes (E83.11 for hemochromatosis) before using this unspecified code

Clinical Significance

Disorder of iron metabolism, unspecified covers confirmed iron metabolism disorders without specification of the type. This may represent hemochromatosis, iron loading disorders, or other iron metabolism abnormalities pending further diagnostic characterization. Iron overload can cause liver disease, cardiomyopathy, diabetes, and endocrine dysfunction if untreated.

Documentation Requirements

✓Provider documentation confirming an iron metabolism disorder
✓Iron studies: serum ferritin, transferrin saturation, serum iron
✓Hepatic assessment if iron overload suspected
✓Reason for lack of specificity (workup in progress, ambiguous results)
✓Genetic testing status for hereditary hemochromatosis (HFE gene)
✓Plan for further diagnostic evaluation or therapeutic phlebotomy

Commonly Confused Codes

E83.110 — Hereditary hemochromatosis: specific genetic iron overload with HFE mutation (most common: C282Y homozygosity)E83.111 — Hemochromatosis due to repeated red blood cell transfusions: secondary/transfusional iron overload E83.119 — Hemochromatosis, unspecified: more specific than E83.10 when hemochromatosis is confirmed but type unknown D50.9 — Iron deficiency anemia, unspecified: LOW iron, opposite of iron overload E61.1 — Iron deficiency: nutritional iron deficiency, not a metabolism disorder
