Type 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as G36.0. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Information
  • A syndrome characterized by acute optic neuritis in combination with acute myelitis, transverse. Demyelinating and/or necrotizing lesions form in one or both optic nerves and in the spinal cord. The onset of optic neuritis and myelitis may be simultaneous or separated by several months. (j neurol neurosurg psychiatry 1996 apr;60(4):382-387)
  • An autoimmune inflammatory syndrome characterized by optic neuritis and myelitis. Signs and symptoms include loss of vision, weakness and paralysis of the extremities, and loss of sensation.
