Chronic multifocal osteomyelitis, right tibia and fibula

This code signifies a persistent, long-term infection of multiple areas within the right tibia and fibula bones. This chronic inflammation and destruction of bone tissue is typically caused by bacteria and can lead to significant pain, swelling, and functional impairment.

Apply this code when documentation clearly indicates a chronic, ongoing osteomyelitis affecting more than one distinct site within the right lower leg bones. Supporting documentation should include imaging reports (X-ray, MRI, bone scan) confirming multifocal involvement and clinical notes detailing the chronic nature of the infection.

• Ensure the documentation specifies "chronic" and "multifocal" to differentiate from acute or localized osteomyelitis.
• Verify the laterality is explicitly stated as "right" to avoid laterality errors.
• Do not use this code for osteomyelitis affecting only one bone or a single site within the tibia or fibula.
