Code Description

ICD-10 D48.112 is a billable code used to indicate a diagnosis of desmoid tumor, intrathoracic.

Key Diagnostic Point:

Desmoid tumors, also known as aggressive fibromatosis, are benign neoplasms that arise from connective tissue and are characterized by their infiltrative growth pattern. Intrathoracic desmoid tumors specifically occur within the thoracic cavity, which can include the pleura, mediastinum, or chest wall. These tumors are classified under neoplasms of uncertain behavior, meaning they do not metastasize like malignant tumors but can exhibit aggressive local behavior, leading to significant morbidity. The etiology of desmoid tumors is often associated with genetic predispositions, particularly in patients with familial adenomatous polyposis (FAP). Clinically, patients may present with chest pain, respiratory symptoms, or incidental findings on imaging studies. Surveillance is critical due to the potential for local recurrence after surgical excision, and management may include observation, surgical resection, or systemic therapies. The unpredictable nature of desmoid tumors necessitates careful monitoring and a multidisciplinary approach to treatment, particularly in the context of their uncertain behavior and potential for progression.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Uncertain behavior classification complicates coding.
  • Variability in clinical presentation and management.
  • Need for precise documentation of tumor location and characteristics.
  • Potential for recurrence requires ongoing surveillance coding.

Audit Risk Factors

  • Inadequate documentation of tumor characteristics.
  • Failure to note the benign nature of the tumor.
  • Misclassification as malignant due to aggressive behavior.
  • Lack of follow-up documentation for surveillance.

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 desmoid tumors, which were previously less clearly defined in ICD-9. This specificity aids in better tracking and management of these tumors.

Frequently Asked Questions

What is the prognosis for patients with desmoid tumors?

Desmoid tumors are benign but can be locally aggressive. Prognosis varies based on tumor location and treatment response, with a risk of recurrence after treatment.
