What This Code Means

A chronic bone infection in the right forearm bones (radius and ulna) that has persisted over time with ongoing bone inflammation.

Coding Tips

• •Confirm documentation specifies 'right' side and involves both radius and ulna or either bone
• •Document whether this is a recurrent infection or a continuation of a previous osteomyelitis episode

Clinical Significance

Chronic osteomyelitis of the right radius and ulna represents a complex bone infection affecting both forearm bones, significantly impacting arm function and hand use. This condition often requires prolonged treatment and may result in permanent functional limitations, particularly affecting grip strength and fine motor activities.

Documentation Requirements

• ✓Documentation of chronic nature (>6 weeks duration or recurrent)
• ✓Specific involvement of right radius and/or ulna bones
• ✓Non-hematogenous etiology (contiguous spread or direct inoculation)
• ✓Imaging studies showing bone infection in forearm bones
• ✓Laboratory evidence of infection or inflammatory markers
• ✓Assessment of right forearm and hand function
• ✓Documentation of treatment regimen and surgical interventions
• ✓Evaluation of impact on activities requiring fine motor control
