Acute hematogenous osteomyelitis, other sites

This code signifies an acute bone infection caused by bacteria or other microorganisms spread through the bloodstream, affecting skeletal sites other than those specifically classified elsewhere (e.g., vertebrae, pelvis, tibia, fibula, femur, humerus, radius, ulna, ankle, foot, hand). It represents a sudden onset inflammatory process within the bone marrow and cortical bone due to systemic dissemination of pathogens.

Apply this code when documentation clearly indicates acute hematogenous osteomyelitis in an unspecified or "other" bone location, such as the clavicle, scapula, or sternum. Supporting documentation should include physician notes detailing the acute nature of the infection, the hematogenous origin, and the specific non-specified bone involved.

• Ensure the documentation specifies "acute" and "hematogenous" to differentiate from chronic or other forms of osteomyelitis.
• Always attempt to code to a more specific anatomical site if documented; this code is for residual "other sites."
• Sequence this code first if it is the primary reason for the encounter, followed by codes for the causative organism if known and documented.
