Acute hematogenous osteomyelitis, left hand

This code signifies an acute bone infection originating from the bloodstream, specifically affecting the bones of the left hand. It indicates a sudden onset inflammatory process within the bone marrow and cortical bone, caused by bacteria or other microorganisms disseminated via the circulatory system.

Apply this code for patients presenting with a new, rapidly developing infection of the left hand bones, confirmed by clinical signs (e.g., pain, swelling, fever), laboratory findings (e.g., elevated inflammatory markers), and imaging (e.g., X-ray, MRI showing bone changes). Documentation should clearly state "acute hematogenous osteomyelitis" and specify the "left hand" as the affected site.

• Ensure the documentation specifies "acute" and "hematogenous" to differentiate from chronic or other forms of osteomyelitis.
• Verify the laterality is clearly documented as "left hand"; do not assume.
• Code any associated infectious organism (e.g., Staphylococcus aureus) as an additional diagnosis, if identified.
