What This Code Means

Death of bone tissue in the radius (forearm bone) caused by medication side effects when the specific side is not specified.

Coding Tips

  • Use only when laterality cannot be determined from documentation; query provider if possible to obtain specific side
  • This code is less specific and may affect reimbursement; bilateral involvement requires separate codes for each side

Clinical Significance

Drug-induced osteonecrosis of unspecified radius indicates medication-related bone death when laterality cannot be determined from documentation. This diagnosis still carries significant implications for forearm function and requires comprehensive management despite the lack of side specification.

Documentation Requirements

  • Clear documentation that radius bone is affected by osteonecrosis
  • Specific drug or medication class identified as causative agent
  • Imaging evidence supporting osteonecrosis diagnosis
  • Clinical presentation including pain and functional limitations
  • Documentation explaining why laterality cannot be determined
  • Treatment approach regardless of side specification
  • Drug exposure history and temporal relationship to symptoms
  • Provider statement confirming drug-induced etiology
