What This Code Means

Death of bone tissue in the left forearm bone (radius) caused by a secondary condition or factor.

Coding Tips

• •Verify laterality is documented as 'left' and the affected bone is the radius
• •Consider impact on pronation/supination function when documenting clinical significance

Clinical Significance

Left radius secondary osteonecrosis represents bone death from identifiable non-traumatic causes affecting the dominant forearm in most patients. This condition significantly impacts wrist function and grip strength, requiring comprehensive management to prevent progression and preserve hand function.

Documentation Requirements

• ✓Clear documentation of secondary cause of osteonecrosis
• ✓Radiological evidence of bone necrosis in left radius
• ✓Clinical assessment demonstrating left forearm/wrist impairment
• ✓History of predisposing conditions or medications
• ✓Exclusion of trauma and idiopathic causes
• ✓Documentation of functional impact on daily activities
• ✓Provider correlation of secondary etiology
• ✓Evidence of bone death through appropriate imaging
