0.000What This Code Means
Death of bone tissue in the right radius (larger forearm bone) due to causes other than trauma or infection, leading to bone deterioration and potential collapse.
Coding Tips
- •Verify laterality is documented as right; if not specified, use M87.833 for unspecified side
- •Investigate and document the underlying cause (idiopathic, radiation, corticosteroid use, etc.) as this may affect treatment decisions
Clinical Significance
Osteonecrosis of the right radius represents a chronic condition affecting the primary weight-bearing bone of the forearm, potentially leading to wrist dysfunction and disability. This diagnosis is clinically significant for risk adjustment as it indicates ongoing orthopedic management needs and potential complications requiring specialized care.
Documentation Requirements
- ✓Specific identification of the right radius as the affected bone
- ✓Documentation of osteonecrosis from causes other than trauma or infection
- ✓Imaging confirmation (MRI, X-ray, bone scan) showing bone necrosis
- ✓Clinical symptoms such as wrist pain, stiffness, or limited range of motion
- ✓Evidence ruling out idiopathic or drug-induced causes
- ✓Assessment of functional impact on wrist and hand mobility
- ✓Documentation of any underlying risk factors or contributing conditions
- ✓Provider evaluation of disease progression and treatment response
