What This Code Means

A long-standing bone infection affecting multiple bones with shoulder involvement, but the specific shoulder (right or left) is not specified.

Coding Tips

• •Use this code only when laterality cannot be determined; attempt to obtain clarification from the provider for more specific coding.
• •Document that the shoulder is involved but laterality is unspecified.

Clinical Significance

Chronic multifocal osteomyelitis with unspecified shoulder laterality indicates a serious systemic bone infection requiring aggressive treatment protocols. While anatomically less specific than lateralized codes, it still represents significant morbidity and healthcare resource demands characteristic of chronic multifocal bone infections.
