  • Use Q07.00 for Arnold-Chiari syndrome without spina bifida or hydrocephalus - BILLABLE CODE

  • Use Q07.01 for Arnold-Chiari syndrome with spina bifida - BILLABLE CODE

  • Use Q07.02 for Arnold-Chiari syndrome with hydrocephalus - BILLABLE CODE

Patient Education


Chiari Malformation

Chiari malformations (CMs) are structural defects in the cerebellum. The cerebellum is the part of the brain that controls balance. With CM, brain tissue extends into the spinal canal. It can happen when part of the skull is too small, which pushes the brain tissue down. There are several types of CM. One type often happens in children who have neural tube defects. Some types cause no symptoms and don't need treatment. If you have symptoms, they may include:

  • Neck pain
  • Balance problems
  • Numbness or other abnormal feelings in the arms or legs
  • Dizziness
  • Vision problems
  • Difficulty swallowing
  • Poor hand coordination

Doctors diagnose CM using imaging tests. Medicines may ease some symptoms, such as pain. Surgery is the only treatment available to correct or stop the progression of nerve damage.
