Code Description

ICD-10 D75 is a billable code used to indicate a diagnosis of other and unspecified diseases of blood and blood-forming organs.

Key Diagnostic Point:

D75 encompasses a variety of conditions affecting the blood and blood-forming organs that do not fall under more specific categories. This includes disorders such as neutropenia, which is characterized by an abnormally low level of neutrophils, a type of white blood cell essential for fighting infections. Neutropenia can arise from various causes, including bone marrow disorders, autoimmune diseases, and certain medications. Additionally, this code covers other white blood cell disorders, which may involve abnormalities in the production or function of leukocytes, leading to increased susceptibility to infections or hematological malignancies. Spleen disorders, such as splenomegaly or hyposplenism, can also be included, as they impact the body's ability to filter blood and produce immune responses. Immunodeficiencies, whether primary (genetic) or secondary (acquired), are also relevant, as they compromise the immune system's ability to respond to pathogens. Accurate coding for D75 requires a thorough understanding of the underlying conditions and their implications for patient management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying conditions that can be coded under D75
  • Need for detailed clinical documentation to support the diagnosis
  • Potential overlap with other hematological codes
  • Variability in clinical presentation and management of conditions

Audit Risk Factors

  • Insufficient documentation to support the diagnosis
  • Inconsistent use of terminology in clinical notes
  • Failure to specify the underlying cause of the disorder
  • Inadequate linkage between diagnosis and treatment provided

Specialty Focus

Medical Specialties

Hematology

Documentation Requirements

Detailed lab results, patient history, and treatment plans must be documented.

Common Clinical Scenarios

Patients presenting with unexplained anemia, leukopenia, or splenic disorders.

Billing Considerations

Ensure that all relevant lab tests and their interpretations are included in the documentation.

Immunology

Documentation Requirements

Comprehensive immunological assessments and patient history of infections.

Common Clinical Scenarios

Patients with recurrent infections or known immunodeficiencies.

Billing Considerations

Document the specific type of immunodeficiency and any related treatments.

Coding Guidelines

Inclusion Criteria

Use D75 When
  • According to ICD
  • 10 coding guidelines, D75 should be used when the specific disease of the blood or blood
  • forming organs is not classified elsewhere
  • Coders must ensure that the diagnosis is supported by clinical documentation and that no more specific code is applicable

Exclusion Criteria

Do NOT use D75 When
No specific exclusions found.

Used to evaluate blood disorders including neutropenia.

Documentation Requirements

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of blood disorders, improving the ability to capture the complexity of conditions like those classified under D75. This has implications for reimbursement and quality reporting.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of blood disorders, improving the ability to capture the complexity of conditions like those classified under D75. This has implications for reimbursement and quality reporting.

Frequently Asked Questions

What conditions are included under D75?

D75 includes various unspecified diseases of blood and blood-forming organs, such as neutropenia, white blood cell disorders, spleen disorders, and immunodeficiencies.

When should I use D75 instead of a more specific code?

D75 should be used when the specific condition affecting the blood or blood-forming organs is not classified elsewhere and when there is insufficient information to assign a more specific code.
