Acute hematogenous osteomyelitis, right tibia and fibula

This diagnosis code signifies an acute bone infection originating from the bloodstream, specifically affecting the right lower leg bones (tibia and fibula). It indicates a sudden onset inflammatory process within the bone marrow and cortical bone, typically caused by bacterial dissemination.

Apply this code when documentation confirms a new, rapidly developing osteomyelitis in the right tibia and fibula, with a clear indication of hematogenous spread. This is often supported by positive blood cultures, imaging (e.g., MRI showing bone edema and periosteal elevation), and clinical signs of acute infection.

• Ensure documentation specifies "acute" and "hematogenous" to differentiate from chronic or other forms of osteomyelitis.
• Verify laterality (right) and the specific bones involved (tibia and fibula) are clearly stated in the medical record.
• Code any associated infectious organism (e.g., Staphylococcus aureus) as an additional diagnosis, if identified.
