What This Code Means

Death of bone tissue in the forearm bone (ulna) due to previous trauma when the specific side is not identified.

Coding Tips

• •Use only when laterality is not documented or cannot be determined
• •Query the provider for clarification on which ulna is affected when documentation is ambiguous

Clinical Significance

Post-traumatic osteonecrosis of the ulna represents a serious long-term complication that can significantly impact forearm function and require complex orthopedic management. This condition indicates compromised bone healing and vascular supply following trauma, often necessitating ongoing monitoring and potential surgical intervention.

Documentation Requirements

• ✓Clear identification of ulna bone involvement
• ✓Documentation of previous trauma or injury to the area
• ✓Clinical evidence of bone necrosis (imaging, physical findings)
• ✓Unspecified laterality explicitly stated or bilaterality documented
• ✓Timeline relationship between trauma and osteonecrosis development
• ✓Current functional status and symptoms
• ✓Any related complications or secondary conditions
• ✓Treatment history and response to interventions
