What This Code Means

Death of bone tissue without infection in the right forearm bone (radius), occurring without a known cause.

Coding Tips

• •The radius is the larger forearm bone on the thumb side; distinguish from ulna
• •Ensure right side is documented to use this specific laterality code

Clinical Significance

Idiopathic aseptic necrosis of the right radius represents bone death in the forearm without identifiable cause, potentially affecting wrist function and grip strength. This condition can significantly impact hand and wrist mobility, requiring specialized orthopedic care and potentially surgical intervention to prevent further bone collapse.

Documentation Requirements

• ✓Documentation of aseptic necrosis specifically affecting right radius bone
• ✓Confirmation of idiopathic etiology with no underlying cause identified
• ✓Imaging evidence demonstrating bone necrosis in right radial structures
• ✓Clear laterality documentation specifying right side involvement
• ✓Clinical exclusion of infectious processes
• ✓Assessment of wrist and forearm function and range of motion
• ✓Treatment plan documentation including therapeutic approaches
• ✓Documentation of pain and functional limitations in daily activities
