What is the ICD-10 code for iron deficiency anemia?

The ICD-10 code for iron deficiency anemia is D50.9, used when anemia is present with low ferritin levels and no specific cause is identified.

How is hereditary hemochromatosis coded?

Hereditary hemochromatosis is coded as E75.22, requiring genetic confirmation and high ferritin and transferrin saturation levels.

Code	Description	When to Use	Key Documentation
D50.9	Iron deficiency anemia, unspecified	Use when anemia is present with low ferritin levels and no specific cause is identified.	Ferritin <30 ng/mL Low hemoglobin levels
E61.1	Iron deficiency	Use for isolated iron deficiency without anemia.	Ferritin <30 ng/mL without anemia
E75.22	Hereditary hemochromatosis	Use when genetic testing confirms hereditary hemochromatosis.	Ferritin >300 ng/mL Transferrin saturation >45% Genetic confirmation (C282Y homozygosity)

Documentation & Coding Risks

Avoid these common issues when documenting Ferritin.

Failing to document genetic testing for hemochromatosis.

Impact

Clinical: Misdiagnosis of hereditary conditions., Regulatory: Non-compliance with coding standards., Financial: Potential claim denials.

Mitigation

Verify genetic test results before coding., Include genetic test documentation in patient records.

Using R79.89 alone for iron deficiency anemia.

Impact

Reimbursement: Claims may be denied if not paired correctly., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate representation of patient condition.

Mitigation

Always pair with D50.9 for iron deficiency anemia.

Coding E75.2 without genetic confirmation.

Impact

Reimbursement: Potential denial of claims without genetic proof., Compliance: Non-compliance with diagnostic criteria., Data Quality: Misleading data on hereditary conditions.

Mitigation

Ensure genetic testing confirms diagnosis before coding.

Improper coding of iron deficiency anemia

Impact

Coding iron deficiency anemia without proper lab documentation.

Mitigation

Ensure all lab results are documented and reviewed before coding.
