Benign neoplasm of mediastinum

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A benign (non-cancerous) tumor that grows in the mediastinum, which is the space in the chest between the lungs that contains the heart, esophagus, and major blood vessels. These tumors are not life-threatening but may require monitoring or removal if they cause symptoms or compress nearby structures.

Coding Tips

  • •Verify the location is specifically the mediastinum and confirm the tumor is benign before assigning this code; malignant mediastinal tumors require different coding
  • •Document whether the neoplasm is causing any complications or symptoms (such as chest pain, cough, or breathing difficulty) as these may warrant additional codes for the manifestations
