Code Description

ICD-10 E61.1 is a billable code used to indicate a diagnosis of iron deficiency.

Key Diagnostic Point:

Iron deficiency is a common nutritional disorder characterized by insufficient iron levels in the body, leading to decreased hemoglobin production and potentially resulting in iron deficiency anemia. This condition can arise from inadequate dietary intake, malabsorption syndromes, chronic blood loss, or increased physiological demands such as during pregnancy or growth spurts in children. Clinically, patients may present with symptoms such as fatigue, pallor, shortness of breath, and dizziness. Diagnosis typically involves laboratory tests including serum ferritin, hemoglobin levels, and complete blood count (CBC). Treatment focuses on dietary modifications to increase iron intake, such as incorporating iron-rich foods (e.g., red meat, leafy greens, legumes) and may include oral or intravenous iron supplementation depending on the severity of the deficiency and the patient's overall health status. Monitoring and follow-up are essential to ensure effective treatment and to prevent recurrence.

  • Understanding the underlying causes of iron deficiency.
  • Documenting dietary history and supplementation accurately.
  • Interpreting laboratory results correctly to support the diagnosis.

Audit Risk Factors

  • Inadequate documentation of dietary history.
  • Failure to document the cause of iron deficiency.
  • Lack of follow-up on treatment efficacy.
  • Misclassification of the severity of deficiency.

Coding Guidelines

Inclusion Criteria

Use E61.1 When
  • According to ICD
  • 10 guidelines, E61
  • 1 should be used when there is clear documentation of iron deficiency without anemia
  • If anemia is present, additional codes may be required to specify the type and cause of anemia
  • It is crucial to document the underlying cause of the deficiency to ensure accurate coding

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of nutritional deficiencies, including iron deficiency, which aids in better tracking and management of these conditions. It emphasizes the importance of documenting the cause and treatment of deficiencies.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of nutritional deficiencies, including iron deficiency, which aids in better tracking and management of these conditions. It emphasizes the importance of documenting the cause and treatment of deficiencies.
