What This Code Means

A sudden bacterial bone infection in the left shoulder that is not blood-borne in origin, often resulting from trauma, surgery, or local spread of infection.

Coding Tips

• •Verify laterality is documented as left; if not specified, use M86.119
• •Distinguish from hematogenous osteomyelitis (M86.07x) which spreads through bloodstream

Clinical Significance

Other acute osteomyelitis of the left shoulder represents non-hematogenous bone infection that can severely compromise shoulder function and quality of life if not treated aggressively. This condition typically results from direct inoculation through trauma or surgery and requires prompt antibiotic therapy to prevent chronic infection and joint destruction.

• ✓Confirmation of non-hematogenous infection origin
• ✓Clinical signs of shoulder bone infection with pain and inflammation
• ✓Radiological evidence of osteomyelitis in left shoulder bones
• ✓Laboratory findings consistent with acute bacterial infection
