Code Description

ICD-10 D63.8 is a billable code used to indicate a diagnosis of anemia in other chronic diseases classified elsewhere.

Key Diagnostic Point:

D63.8 refers to anemia that occurs as a complication of other chronic diseases that are classified in different categories. This includes conditions such as aplastic anemia, which is characterized by the failure of the bone marrow to produce sufficient blood cells, leading to a deficiency in red blood cells, white blood cells, and platelets. Bone marrow failure syndromes can be acquired due to various factors, including autoimmune diseases, infections, or exposure to certain drugs or toxins. Acquired anemias can also arise from chronic diseases such as chronic kidney disease, malignancies, or inflammatory disorders. These conditions often lead to a complex interplay of factors that contribute to anemia, including reduced erythropoietin production, iron deficiency, and the effects of chronic inflammation on iron metabolism. Accurate coding for D63.8 requires a thorough understanding of the underlying chronic disease and its relationship to the anemia, as well as careful documentation of the patient's clinical status and treatment plan.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying chronic diseases that can cause anemia
  • Need for detailed documentation of the primary disease
  • Differentiation between types of anemia (e.g., aplastic vs. iron deficiency)
  • Potential for overlapping symptoms with other conditions

Audit Risk Factors

  • Inadequate documentation of the underlying chronic disease
  • Failure to specify the type of anemia
  • Lack of clarity on the relationship between the chronic disease and anemia
  • Inconsistent coding practices among different providers

Specialty Focus

Medical Specialties

Hematology

Documentation Requirements

Detailed lab results, patient history, and treatment plans must be documented to support the diagnosis of anemia and its underlying cause.

Common Clinical Scenarios

Patients with chronic kidney disease presenting with anemia, patients with autoimmune disorders leading to aplastic anemia.

Billing Considerations

Hematologists must ensure that the relationship between the chronic disease and anemia is clearly articulated in the medical record.

Internal Medicine

Documentation Requirements

Comprehensive assessment of the patient's chronic conditions and their management, including any treatments for anemia.

Common Clinical Scenarios

Patients with multiple chronic conditions such as diabetes and chronic lung disease presenting with anemia.

Billing Considerations

Internal medicine providers should document the impact of chronic diseases on anemia and any interventions undertaken.

Coding Guidelines

Inclusion Criteria

Use D63.8 When
  • According to ICD
  • 10 coding guidelines, D63
  • 8 should be used when anemia is a direct result of a chronic disease classified elsewhere
  • Coders must ensure that the primary disease is documented and coded appropriately, and that D63
  • 8 is used as a secondary code to reflect the anemia

Exclusion Criteria

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of anemia related to chronic diseases, improving the accuracy of data collection and reimbursement processes. D63.8 provides a means to capture the complexity of anemia in patients with multiple chronic conditions.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of anemia related to chronic diseases, improving the accuracy of data collection and reimbursement processes. D63.8 provides a means to capture the complexity of anemia in patients with multiple chronic conditions.

Reimbursement & Billing Impact

reimbursement processes. D63.8 provides a means to capture the complexity of anemia in patients with multiple chronic conditions.
