Deficiency of other nutrients
Includes iron deficiency without anemia, relevant for isolated low ferritin.
Disorders of sphingolipid metabolism and other lipid storage disorders
Includes hereditary hemochromatosis, related to high ferritin 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. |
|
| E61.1 | Iron deficiency | Use for isolated iron deficiency without anemia. |
|
| E75.22 | Hereditary hemochromatosis | Use when genetic testing confirms hereditary hemochromatosis. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

- Low hemoglobin levels
Code-Specific Risks
- Misclassification if underlying cause is known but not documented.
Coding Notes
- Ensure documentation specifies iron deficiency as the cause of anemia.
E61.1 - Iron deficiency
Use for isolated iron deficiency without anemia.
Applicable To
- Iron deficiency NOS
Excludes
- Iron deficiency anemia (D50.-)
Clinical Validation Requirements
- Ferritin <30 ng/mL without anemia
Coding Notes
Ensure documentation clearly states iron deficiency without anemia.
E75.22 - Hereditary hemochromatosis
Use when genetic testing confirms hereditary hemochromatosis.
Applicable To
- HFE-associated hemochromatosis
Excludes
- Secondary hemochromatosis (E83.1)
Clinical Validation Requirements
- Ferritin >300 ng/mL
- Transferrin saturation >45%
- Genetic confirmation (C282Y homozygosity)
Coding Notes
Document genetic test results and clinical findings.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Ferritin to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D50.9.
Impact
Clinical: Misdiagnosis of hereditary conditions., Regulatory: Non-compliance with coding standards., Financial: Potential claim denials.
Mitigation Strategy
Verify genetic test results before coding., Include genetic test documentation in patient records.
Impact
Reimbursement: Claims may be denied if not paired correctly., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate representation of patient condition.
Mitigation Strategy
Always pair with D50.9 for iron deficiency anemia.
Impact
Reimbursement: Potential denial of claims without genetic proof., Compliance: Non-compliance with diagnostic criteria., Data Quality: Misleading data on hereditary conditions.
Mitigation Strategy
Ensure genetic testing confirms diagnosis before coding.
Impact
Coding iron deficiency anemia without proper lab documentation.
Mitigation Strategy
Ensure all lab results are documented and reviewed before coding.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
