What This Code Means

A rapidly developing bone infection affecting the right ankle and foot bones.

Coding Tips

  • Verify that the infection involves the ankle and/or foot structures, not the tibia/fibula
  • Document which specific foot bones are involved if possible for clinical clarity

Clinical Significance

Acute osteomyelitis of the right ankle and foot represents a complex infection affecting multiple small bones critical for weight-bearing and mobility. This condition poses significant risks for chronic disability and requires immediate intervention to preserve foot function and prevent systemic complications.

Documentation Requirements

  • Specific identification of right ankle and foot involvement
  • Documentation of acute onset bone infection
  • Clinical evidence of ankle/foot bone infection
  • Imaging confirmation of osteomyelitis in ankle/foot bones
  • Laboratory support for active infection
  • Assessment of weight-bearing capacity and gait
  • Documentation of pain and functional limitations
  • Treatment plan addressing complex foot anatomy
