Code Description

ICD-10 D47.9 is a billable code used to indicate a diagnosis of neoplasm of uncertain behavior of lymphoid, hematopoietic and related tissue, unspecified.

Key Diagnostic Point:

D47.9 refers to neoplasms of uncertain behavior that arise from lymphoid, hematopoietic, and related tissues. These neoplasms are characterized by their ambiguous nature, where the potential for malignancy is not clearly defined. Clinically, these neoplasms may present with symptoms such as lymphadenopathy, splenomegaly, or other hematological abnormalities. The uncertainty in behavior necessitates careful monitoring and evaluation, as some neoplasms may progress to malignancy while others may remain indolent. Diagnosis typically involves a combination of imaging studies, laboratory tests, and histopathological examination. The management of patients with D47.9 often includes regular surveillance to detect any changes in the neoplasm's behavior, as well as potential interventions based on clinical findings. Accurate coding is crucial for appropriate treatment planning and resource allocation in healthcare settings.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Ambiguity in clinical presentation and behavior of the neoplasm
  • Need for comprehensive documentation to support diagnosis
  • Variability in treatment approaches based on individual patient factors
  • Potential for progression to malignancy requiring ongoing surveillance

Audit Risk Factors

  • Inadequate documentation of clinical findings
  • Failure to document surveillance plans or follow-up
  • Misclassification of neoplasm behavior
  • Inconsistent coding practices among different providers

Specialty Focus

Medical Specialties

Hematology/Oncology

Documentation Requirements

Detailed pathology reports, imaging studies, and treatment plans must be documented to support the diagnosis.

Common Clinical Scenarios

Patients presenting with lymphadenopathy or unexplained cytopenias requiring further evaluation.

Billing Considerations

Close monitoring and documentation of any changes in the neoplasm's behavior are essential for accurate coding.

Pathology

Documentation Requirements

Comprehensive histopathological reports that detail the characteristics of the neoplasm.

Common Clinical Scenarios

Biopsy specimens from lymph nodes or bone marrow showing atypical lymphoid cells.

Billing Considerations

Pathologists must clearly indicate the behavior of the neoplasm to assist coders in accurate coding.

Coding Guidelines

Inclusion Criteria

Use D47.9 When
  • According to ICD
  • 10 coding guidelines, D47
  • 9 should be used when the neoplasm's behavior is uncertain and cannot be classified more specifically
  • Coders should ensure that the documentation supports the diagnosis and that the neoplasm is not better classified under a more specific code

Exclusion Criteria

Do NOT use D47.9 When
No specific exclusions found.
