Acute hematogenous osteomyelitis, right femur

This code signifies an acute infection of the bone marrow and surrounding bone tissue in the right femur, caused by bacteria or other microorganisms spread through the bloodstream. It represents a rapidly developing inflammatory process within the bone.

Apply this code when documentation clearly indicates a new onset, hematogenously spread osteomyelitis affecting the right femur. Supporting documentation should include clinical signs of acute infection (e.g., fever, pain, swelling), laboratory findings (e.g., elevated WBC, ESR, CRP), and imaging results (e.g., MRI, X-ray) confirming bone involvement.

• Ensure documentation specifies "acute" and "hematogenous" to differentiate from chronic or other forms of osteomyelitis.
• Verify the laterality (right femur) is explicitly stated in the medical record.
• Code any associated infectious organism (e.g., Staphylococcus aureus) as an additional diagnosis.
