0.000What This Code Means
Death of bone tissue in the right thighbone (femur) caused by medication side effects, commonly seen with corticosteroid use and affecting weight-bearing.
Coding Tips
- •Femoral head osteonecrosis is a common complication of long-term corticosteroid therapy; document steroid use history
- •Specify right femur to distinguish from left femur or bilateral involvement which would require separate coding
Clinical Significance
Drug-induced osteonecrosis of the right femur represents a serious medication-related complication affecting the primary weight-bearing bone, often involving the femoral head and potentially requiring joint replacement. This condition significantly impacts mobility and quality of life, necessitating comprehensive orthopedic care.
Documentation Requirements
- ✓Specific documentation of right femur involvement in osteonecrosis
- ✓Causative medication identification with exposure timeline
- ✓Imaging studies confirming femoral osteonecrosis (MRI preferred)
- ✓Assessment of hip joint function and weight-bearing capacity
- ✓Documentation of pain severity and mobility limitations
- ✓Drug exposure duration and correlation with symptom onset
- ✓Treatment plan including conservative vs surgical management
- ✓Provider assessment linking drug use to osteonecrosis development
