What This Code Means

A bone infection of unspecified type (not specifically chronic or acute) that is affecting multiple sites in the body.

Coding Tips

•Clarify with the provider whether this is acute or chronic osteomyelitis, as more specific codes may be appropriate
•Document all affected anatomical sites to support the multiple sites designation

Clinical Significance

Other osteomyelitis affecting multiple sites represents bone infections that don't fit standard acute or chronic classifications but involve multiple anatomical locations. This indicates complex infectious processes requiring specialized evaluation and treatment, with potential for significant morbidity and healthcare resource utilization across multiple body systems.

Documentation Requirements

✓Documentation of osteomyelitis diagnosis with multiple site involvement
✓Specification of affected anatomical locations
✓Clinical justification for 'other' classification rather than acute or chronic
✓Supporting diagnostic imaging for each affected site
✓Laboratory studies confirming infection
✓Treatment plan addressing multiple site involvement
✓Assessment of functional impact across affected areas
✓Documentation of any unique characteristics justifying 'other' classification

Commonly Confused Codes

M86.69 — Chronic osteomyelitis multiple sites has established chronicity M86.19 — Acute osteomyelitis multiple sites has acute presentation M86.9 — Unspecified osteomyelitis doesn't specify multiple site involvement M87.09 — Aseptic necrosis multiple sites lacks infectious component
