0.000What This Code Means
A malignant (cancerous) tumor in the soft tissues or connective tissues of the right lower leg, thigh, or hip.
Coding Tips
- •Ensure documentation clearly indicates the tumor is on the right side; if left side is documented, use C49.22 instead
- •This code includes soft tissue sarcomas and other malignant connective tissue tumors of the right lower extremity
Clinical Significance
Malignant neoplasm of connective and soft tissue of the right lower limb including hip. The thigh is the single most common site for soft tissue sarcomas in the body, making laterality-specific coding particularly important for tracking and research purposes in this high-volume anatomical region.
Documentation Requirements
- ✓Right-sided laterality documented in medical record
- ✓Pathology confirming malignant soft tissue neoplasm with histological subtype
- ✓Specific location within the right lower limb (thigh, leg, foot)
- ✓Tumor size (greatest dimension), grade, and depth relative to fascia
- ✓Surgical margins and reconstruction details if resected
