Code Description

ICD-10 D38.2 is a billable code used to indicate a diagnosis of neoplasm of uncertain behavior of pleura.

Key Diagnostic Point:

Neoplasms of uncertain behavior of the pleura are abnormal growths that arise from the pleural tissue, which lines the thoracic cavity and surrounds the lungs. These neoplasms can be benign or malignant, but their uncertain behavior indicates that their potential for progression or metastasis is not clearly defined. Clinically, these neoplasms may present with symptoms such as chest pain, dyspnea, or pleuritic pain, and they may be discovered incidentally on imaging studies. Diagnosis typically involves imaging modalities such as chest X-rays, CT scans, or MRI, followed by histopathological examination through biopsy to ascertain the nature of the neoplasm. Surveillance is crucial, as these neoplasms may require monitoring for changes in size or behavior, which could indicate malignant transformation. The management of patients with pleural neoplasms of uncertain behavior often involves a multidisciplinary approach, including oncologists, pulmonologists, and thoracic surgeons, to determine the best course of action based on individual patient factors and the characteristics of the neoplasm.

Complexity Factors

  • Variability in clinical presentation and symptoms
  • Need for comprehensive diagnostic workup including imaging and biopsy
  • Potential for misclassification between benign and malignant neoplasms
  • Documentation of surveillance and follow-up care

Audit Risk Factors

  • Inadequate documentation of diagnostic imaging results
  • Failure to document the rationale for surveillance
  • Misclassification of neoplasm behavior
  • Lack of follow-up documentation

Coding Guidelines

Inclusion Criteria

Use D38.2 When
  • According to ICD
  • 10 coding guidelines, D38
  • 2 should be used when the neoplasm's behavior is uncertain and cannot be classified as benign or malignant
  • Coders should ensure that the documentation supports the diagnosis and reflects the uncertainty of behavior

Thoracentesis, needle drainage of pleural effusion

Clinical Scenario

Used when a pleural effusion is present and needs to be drained for diagnostic or therapeutic purposes.

Documentation Requirements

Document the indication for the procedure, the amount of fluid removed, and any cytological analysis performed.

Specialty Considerations

Pulmonologists should ensure that the procedure is justified based on clinical findings.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of neoplasms, including those of uncertain behavior. This specificity aids in better tracking of patient outcomes and resource allocation for surveillance and treatment.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of neoplasms, including those of uncertain behavior. This specificity aids in better tracking of patient outcomes and resource allocation for surveillance and treatment.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of neoplasms, including those of uncertain behavior. This specificity aids in better tracking of patient outcomes and resource allocation for surveillance and treatment.
