What This Code Means

A bone infection in the left upper arm bone (humerus) that develops gradually over weeks to months, causing inflammation and potential bone damage.

Coding Tips

  • Ensure documentation clearly identifies the humerus as the affected bone on the left side
  • Note any associated complications such as abscess formation or sequestrum in the medical record

Clinical Significance

Subacute osteomyelitis of the left humerus represents a bone infection with gradual onset affecting the major upper arm bone over weeks to months. This intermediate phase infection requires monitoring to prevent progression to chronic osteomyelitis and preserve upper extremity function.

Documentation Requirements

  • Specific identification of left humerus involvement
  • Documentation of subacute infection timeline
  • Clinical evidence of humeral bone infection
  • Imaging confirmation of osteomyelitis in left humerus
  • Laboratory evidence of ongoing bone infection
  • Assessment of arm function and range of motion
  • Documentation of symptom progression
  • Treatment plan to prevent chronic conversion
