What This Code Means

A chronic bone infection affecting multiple areas of the left shin bone and smaller bone next to it, characterized by persistent inflammation and potential drainage.

Coding Tips

  • Verify laterality is documented as 'left' in the medical record before assigning this code
  • Confirm the infection is multifocal (multiple sites) and chronic (long-standing) rather than acute

Clinical Significance

This diagnosis captures chronic multifocal osteomyelitis of the left tibia and fibula, a serious condition affecting both bones of the lower leg with significant implications for mobility and function. The multifocal nature indicates extensive disease requiring aggressive treatment and monitoring.

Documentation Requirements

  • Clear documentation of left tibia and fibula involvement
  • Evidence supporting chronic nature (duration >6 weeks or recurrent)
  • Confirmation of multifocal pattern in both bones
  • Imaging studies demonstrating chronic osteomyelitic changes
  • Functional assessment of left lower extremity
  • Laboratory markers consistent with chronic infection
  • Treatment history including medical and surgical approaches
  • Clinical correlation with chronic multifocal osteomyelitis
