Acute hematogenous osteomyelitis, left radius and ulna

This code signifies an acute bone infection originating from a bloodstream infection, specifically affecting the left radius and ulna. It indicates a sudden onset inflammatory process within the bone marrow and surrounding bone tissue of the forearm, caused by bacteria or other microorganisms disseminated through the blood.

Apply this code for patients presenting with a new onset of osteomyelitis in the left forearm bones, where the infection is attributed to hematogenous spread. Documentation should clearly state "acute hematogenous osteomyelitis" and specify the left radius and ulna as the affected sites, often supported by imaging and laboratory findings (e.g., elevated inflammatory markers, positive blood cultures).

• Ensure documentation specifies "acute" and "hematogenous" to differentiate from chronic or other forms of osteomyelitis.
• Verify the laterality (left) and specific bones (radius and ulna) are clearly documented; do not use if only one bone is affected or if the laterality is unspecified.
• Code any underlying systemic infection (e.g., bacteremia, sepsis) as a primary diagnosis when applicable, following sequencing guidelines.
