0.000What This Code Means
Death of bone tissue in the right foot due to causes other than trauma or radiation.
Coding Tips
- •Verify right foot is documented; foot osteonecrosis may involve tarsal bones, metatarsals, or other foot structures
- •Document which specific foot bone is affected if the clinical record provides this detail
Clinical Significance
Right foot osteonecrosis involves avascular bone death in the complex foot architecture, potentially affecting multiple bones and compromising weight-bearing function. This condition can significantly impact mobility and may require specialized orthopedic foot and ankle management.
Documentation Requirements
- ✓Specific identification of right foot involvement
- ✓Detailed imaging identifying affected foot bones
- ✓Documentation excluding trauma, infection, or radiation causes
- ✓Weight-bearing capacity and gait analysis
- ✓Pain assessment and functional limitations
- ✓Evaluation for underlying systemic conditions
- ✓Podiatric or orthopedic consultation documentation
- ✓Treatment plan including offloading strategies
