0.000What This Code Means
Death of bone tissue in the left radius (larger forearm bone) due to causes other than trauma or infection, leading to bone deterioration and potential collapse.
Coding Tips
- •Confirm left side is clearly documented in the medical record to avoid coding errors
- •Document any associated conditions or risk factors that may have contributed to the osteonecrosis
Clinical Significance
Osteonecrosis of the left radius is a chronic bone condition that can significantly impact wrist and hand function, leading to disability and reduced quality of life. This diagnosis carries important risk adjustment implications as it indicates a complex orthopedic condition requiring ongoing specialist care and potential surgical intervention.
Documentation Requirements
- ✓Clear specification of the left radius as the affected bone
- ✓Documentation that osteonecrosis is from causes other than idiopathic or drug-induced
- ✓Radiological evidence (MRI, CT, X-ray) confirming bone necrosis
- ✓Clinical presentation including pain, functional limitation, or joint stiffness
- ✓Exclusion of infectious causes or trauma as primary etiology
- ✓Assessment of impact on activities of daily living and work function
- ✓Documentation of any predisposing factors or underlying conditions
- ✓Provider evaluation of treatment needs and prognosis
