Other osteomyelitis, shoulder

This code represents an infection of the bone and bone marrow within the shoulder region, not specifically classified as acute, chronic, or due to a prosthetic joint. It encompasses various forms of osteomyelitis affecting the humerus, scapula, or clavicle at or near the shoulder joint.

This code is appropriate for documented cases of osteomyelitis affecting the shoulder when the specific type (e.g., acute hematogenous, chronic multifocal) is not further specified or when the etiology is unusual and not covered by more specific codes. Documentation should clearly indicate osteomyelitis of the shoulder and rule out prosthetic joint involvement.

• Ensure documentation specifies "shoulder" as the anatomical site; avoid using for osteomyelitis of other upper limb bones.
• Distinguish from osteomyelitis due to prosthetic joint, which has specific T84.6 or T84.7 codes.
• Always sequence a code for the infectious agent (e.g., B95-B97) as an additional diagnosis, if known.
