0.000What This Code Means
Death of bone tissue in the left toe(s) caused by a previous injury or trauma.
Coding Tips
- •Confirm laterality is documented as 'left' and identify if single or multiple toes are involved
- •Distinguish toe osteonecrosis from metatarsal or other foot bone involvement
Clinical Significance
Left toe osteonecrosis secondary to trauma affects the terminal weight-bearing structures important for normal gait and balance. This condition can impact push-off mechanics during ambulation and may require specialized foot care to prevent further complications and preserve function.
Documentation Requirements
- ✓Clear identification of left toe(s) involvement
- ✓Documentation of previous trauma to left toe(s)
- ✓Evidence of bone necrosis in left toe bone structures
- ✓Specification of affected toes when documented
- ✓Assessment of gait mechanics and balance impact
- ✓Current pain evaluation and functional capacity
- ✓Treatment modalities attempted and effectiveness
- ✓Impact on ambulation and weight-bearing activities
