What This Code Means

A chronic bone infection affecting multiple areas of the right forearm bones (radius and ulna), characterized by persistent inflammation and bone damage.

Coding Tips

  • Verify laterality is documented as right in the medical record before assigning this code
  • Confirm the infection is multifocal (affecting multiple sites) and chronic in nature, not acute

Clinical Significance

This code represents a severe chronic bone infection specifically affecting both forearm bones of the right arm, indicating significant functional impairment and treatment complexity. The multifocal nature suggests extensive disease requiring prolonged antibiotic therapy and potential surgical intervention.

Documentation Requirements

  • Confirmation of right-sided radius and ulna involvement
  • Evidence of chronicity (>6 weeks duration or recurrent episodes)
  • Documentation of multifocal pattern (multiple areas within bones)
  • Radiographic evidence of osteomyelitic changes on imaging
  • Clinical symptoms (pain, swelling, decreased range of motion)
  • Laboratory markers (elevated inflammatory markers, culture results)
  • Treatment response documentation (antibiotic therapy outcomes)
  • Provider assessment confirming chronic multifocal osteomyelitis
