Chronic multifocal osteomyelitis, right shoulder

This code signifies a persistent, widespread infection of the bone and bone marrow affecting multiple sites, specifically in the right shoulder. It indicates a long-standing inflammatory process that has spread beyond a single focal point within the bone.

Apply this code when documentation confirms a chronic osteomyelitis with evidence of multifocal involvement, explicitly located in the right shoulder. This typically involves persistent pain, swelling, and imaging findings (e.g., MRI, bone scan) consistent with widespread bone infection in this anatomical area.

• Ensure documentation clearly specifies "chronic" and "multifocal" to differentiate from acute or localized osteomyelitis.
• Verify the laterality (right shoulder) is explicitly stated in the medical record.
• Do not use for acute osteomyelitis or if the infection is localized to a single area within the shoulder.
