What This Code Means

A bone infection (osteomyelitis) affecting the upper arm that doesn't fit into other specific osteomyelitis categories.

Coding Tips

  • Verify whether the infection is in the humerus or surrounding bone tissue to ensure accurate coding
  • Confirm this is not acute or chronic osteomyelitis, which would require different codes

Clinical Significance

Other osteomyelitis of the upper arm indicates bone infection of the humerus that doesn't fit standard acute or chronic patterns. This condition affects a major weight-bearing bone of the upper extremity and can significantly impact arm function, requiring comprehensive evaluation and treatment to prevent complications such as pathological fracture or chronic disability.

Documentation Requirements

  • Clear osteomyelitis diagnosis involving upper arm/humerus
  • Documentation justifying 'other' versus acute or chronic classification
  • Specification of humerus involvement and extent
  • Imaging studies confirming bone infection
  • Microbiological studies or tissue sampling when performed
  • Treatment regimen including antibiotic selection and duration
  • Functional assessment of upper extremity
  • Documentation of unique clinical features supporting 'other' designation
