Other chronic hematogenous osteomyelitis, right femur

This code signifies a persistent, long-term infection of the right femur bone that originated from a bloodstream infection (hematogenous spread), but is not classified as acute or subacute. It indicates a chronic inflammatory process within the bone marrow and cortical bone of the right thigh bone due to bacterial or fungal pathogens.

Apply this code when documentation clearly states "chronic hematogenous osteomyelitis" affecting the right femur. This typically follows an initial acute infection that was not fully eradicated and has transitioned into a chronic state. Supporting documentation includes imaging (X-ray, MRI, bone scan) showing chronic osteomyelitis changes, positive bone cultures, and a history of prior bacteremia or sepsis.

• Ensure documentation specifies "chronic" and "hematogenous" to differentiate from acute or direct inoculation osteomyelitis.
• Laterality (right femur) is crucial; do not use for left or unspecified femur.
• Sequence this code after any underlying systemic infection (e.g., sepsis) if still active and contributing to the osteomyelitis.
