Other chronic hematogenous osteomyelitis, right shoulder

This code signifies a persistent, long-standing infection of the bone and bone marrow in the right shoulder, specifically caused by pathogens spread through the bloodstream, but not classified as acute or subacute. It indicates an ongoing inflammatory process affecting the osseous structures of the right shoulder joint.

Apply this code when documentation confirms a chronic osteomyelitis of hematogenous origin affecting the right shoulder. This typically involves a history of infection, persistent symptoms, and imaging (e.g., X-ray, MRI) or biopsy findings consistent with chronic bone infection in this specific anatomical location.

• Ensure documentation clearly specifies "chronic" and "hematogenous" etiology, as well as the "right shoulder" laterality.
• Distinguish from acute (M86.1-) or subacute (M86.2-) osteomyelitis, which have different code assignments.
• Code any associated infectious organism (e.g., B95-B97) as an additional diagnosis, if identified.
