0.000What This Code Means
Death of bone tissue in the forearm bone (radius) due to previous trauma when the specific side is not identified.
Coding Tips
- •Use only when the medical record does not specify right or left radius
- •Request clarification from the provider regarding laterality when possible
Clinical Significance
Unspecified radius osteonecrosis due to trauma indicates compromised bone viability following injury when laterality cannot be determined. This condition requires careful evaluation for potential surgical intervention and monitoring for functional decline in forearm mechanics.
Documentation Requirements
- ✓Clear documentation of previous radius trauma without specified side
- ✓Imaging confirmation of osteonecrosis in radius bone
- ✓Clinical evidence of forearm dysfunction or pain
- ✓Exclusion of non-traumatic etiologies for osteonecrosis
- ✓Documentation explaining why laterality is unspecified
- ✓Provider assessment linking trauma history to current necrosis
- ✓Evidence of bone death through appropriate diagnostic studies
- ✓Assessment of functional impact on upper extremity
