Other chronic hematogenous osteomyelitis, right humerus

This code signifies a persistent, long-term infection of the bone marrow and bone tissue in the right upper arm, specifically caused by pathogens spread through the bloodstream. It indicates a non-acute inflammatory process within the humerus resulting from hematogenous dissemination of bacteria or other microorganisms.

Apply this code when documentation confirms a chronic osteomyelitis affecting the right humerus, where the infection originated from a systemic source (e.g., bacteremia, distant infection). Supporting documentation should detail the chronicity of the infection, the specific bone involved, and evidence or strong suspicion of hematogenous spread.

• Differentiate from acute osteomyelitis; look for terms like "chronic," "long-standing," or evidence of prolonged treatment.
• Ensure laterality is clearly documented as "right humerus"; avoid using for unspecified or left-sided infections.
• Code also any associated infectious organism (e.g., B95-B97) if identified and documented.
