Acute hematogenous osteomyelitis, right ankle and foot

This code signifies an acute bone infection originating from a bloodstream infection, specifically affecting the bones of the right ankle and/or foot. It indicates a rapid onset inflammatory process within the bone marrow and cortical bone, typically caused by bacteria.

Apply this code when documentation clearly states a diagnosis of acute hematogenous osteomyelitis localized to the right ankle or foot. This diagnosis is often supported by positive blood cultures, imaging findings (e.g., MRI showing bone edema and marrow changes), and clinical signs of acute infection such as fever, pain, and swelling.

• Ensure documentation specifies "acute" and "hematogenous" to differentiate from chronic or other forms of osteomyelitis.
• Verify the laterality and specific anatomical site (ankle and/or foot) are clearly stated.
• Consider sequencing this code after the underlying systemic infection (e.g., bacteremia) if applicable and still active.
