- •Query the provider if more specific anatomical information is available to use a more precise code
Clinical Significance
Malignant neoplasm of connective and soft tissue of trunk, unspecified is a non-specific code used when the trunk location of a soft tissue sarcoma cannot be determined. More specific codes for thorax (C49.3), abdomen (C49.4), or pelvis (C49.5) should be used when the specific trunk region is documented.
Documentation Requirements
- ✓Pathology confirming malignant soft tissue neoplasm in the trunk
- ✓Query provider for specific trunk region (thorax, abdomen, pelvis)
- ✓Documentation explaining why specific trunk site cannot be determined
- ✓Treatment status and disease monitoring plan
- ✓Imaging that may contain more specific site information
