What This Code Means

Death of bone tissue in the pelvis caused by an underlying condition or treatment, which can affect mobility and cause chronic pain.

Coding Tips

• •Pelvic osteonecrosis is less common than femoral involvement; ensure documentation supports this location
• •Always identify and code the underlying etiology separately

Clinical Significance

This diagnosis represents secondary osteonecrosis of the pelvis caused by underlying conditions, which can severely impact mobility and weight-bearing capacity. It requires aggressive management of the underlying cause and monitoring for potential complications including hip joint involvement.

Documentation Requirements

• ✓Documentation of osteonecrosis affecting pelvis
• ✓Identification of underlying cause (e.g., corticosteroid use, radiation therapy, sickle cell disease)
• ✓Imaging findings confirming pelvic bone necrosis (MRI, X-ray, CT)
• ✓Clinical symptoms such as groin pain, hip pain, or difficulty walking
• ✓Specific pelvic bones affected (ilium, ischium, pubis)
• ✓Functional limitations and mobility issues
• ✓Duration and progression of condition
• ✓Treatment history and response
