Clinical Significance
Malignant neoplasm of the left upper limb is the left-sided counterpart for ill-defined upper extremity malignancies. As with the right-sided code, the specific tissue of origin cannot be determined from available documentation. Provider query and pathology review should be pursued to assign a more tissue-specific code when possible.
Documentation Requirements
- ✓Documentation confirming left upper limb malignancy
- ✓Pathology with tissue typing
- ✓Imaging documenting location and extent within the left upper extremity
- ✓Functional assessment and neurovascular status
- ✓Treatment plan
