Other chronic hematogenous osteomyelitis, left femur

This code signifies a persistent, long-term infection of the bone marrow and bone tissue in the left femur, caused by pathogens spread through the bloodstream. This condition is characterized by ongoing inflammation and bone destruction, often leading to sequestra formation and involucrum.

Use this code when documentation explicitly states chronic hematogenous osteomyelitis affecting the left femur. This diagnosis typically follows an initial acute infection that was not fully resolved or has recurred. Supporting documentation should include imaging reports (X-ray, MRI, CT) showing chronic changes, culture results confirming hematogenous spread, and physician notes detailing the chronicity and specific anatomical site.

• Ensure the documentation specifies "chronic" and "hematogenous" to differentiate from acute or other forms of osteomyelitis.
• Verify the laterality and specific bone (femur) are clearly stated in the medical record.
• Consider sequencing this code after any underlying systemic infection that led to the hematogenous spread, if applicable.
