Other acute osteomyelitis, unspecified radius and ulna

This code signifies an acute inflammatory process of the bone and bone marrow, specifically affecting the radius and ulna, that is not further specified as to its cause. It indicates a sudden onset infection within these forearm bones, without detailing the infectious agent or specific location within the radius or ulna.

Use this code when documentation confirms acute osteomyelitis involving the radius and ulna, but the specific bone (radius or ulna) is not clearly identified, and the laterality (left or right) is also unspecified. This code is appropriate when the physician's notes indicate "acute osteomyelitis of the forearm" or "acute osteomyelitis of radius/ulna" without further anatomical or etiological detail.

• Ensure documentation explicitly states "acute" osteomyelitis; chronic osteomyelitis codes are distinct.
• Avoid using this code if the specific radius or ulna is identified, or if laterality is documented (e.g., right radius, left ulna).
• Always attempt to query the provider for more specific anatomical location and laterality to allow for a more precise code selection.
