Gives specialists in the clinical neurosciences a detailed and authoritative instrument for coding virtually all recognized neurological conditions. Both neurological diseases and neurological manifestations of general diseases and injuries are included in this comprehensive coding tool. The volume is part of a growing family of specialty-based adaptations of ICD-10 which retain the "core" codes of the parent classification while providing extended detail at the fifth character and beyond. Now in its second edition, ICD-NA has been revised to reflect current clinical concepts in the neurosciences as well as the new coding system introduced with ICD-10. The classification was finalized following extensive consultation with numerous professional organizations and international experts, thus ensuring the representation of as many viewpoints as are practical and consistent.
