What This Code Means

A bone infection in the radius and ulna (forearm bones) caused by bacteria spreading through the bloodstream, with the specific side not documented.

Coding Tips

• •Use this code only when laterality (left/right) cannot be determined from documentation
• •Verify if the infection is truly hematogenous (blood-borne) versus other routes of infection

Clinical Significance

Acute hematogenous osteomyelitis of unspecified radius and ulna represents serious bloodstream-spread infection to forearm bones when laterality is not documented, requiring immediate aggressive treatment. This dual bone involvement creates high risk for compartment syndrome and functional impairment, though optimal care planning may benefit from laterality clarification.

Documentation Requirements

• ✓Documentation of acute osteomyelitis affecting radius and ulna
• ✓Evidence of hematogenous spread without laterality specification
• ✓Clinical findings of forearm bone infection
• ✓Imaging studies showing dual bone involvement
• ✓Blood and bone cultures when available
• ✓Treatment with IV antibiotics and surgical consideration
• ✓Assessment for compartment syndrome risk
