0.000What This Code Means
Death of bone tissue in the right foot caused by medication side effects, potentially affecting multiple foot bones and walking ability.
Coding Tips
- •Specify which foot bone(s) are involved (metatarsals, tarsals, etc.) if documented for greater specificity
- •Document the timeline of medication use relative to osteonecrosis onset to establish causality
Clinical Significance
Drug-induced osteonecrosis of the right foot represents medication-related bone death affecting multiple foot structures, potentially causing severe functional impairment and mobility limitations. This condition may require specialized podiatric and orthopedic care to preserve foot function and prevent amputation.
Documentation Requirements
- ✓Clear documentation of right foot involvement in osteonecrosis
- ✓Specific causative medication identification with exposure details
- ✓Comprehensive imaging showing extent of foot bone necrosis
- ✓Assessment of weight-bearing capacity and gait abnormalities
- ✓Documentation of impact on mobility and daily activities
- ✓Drug therapy timeline and correlation with symptom development
- ✓Multidisciplinary treatment plan including podiatric care
- ✓Provider statement establishing drug-induced etiology
