Clinical notes

Excludes2 (not included here)

An Excludes2 note means the excluded condition is not part of this one, but a patient can have both at the same time — in that case both codes may be reported together.

  • obsessive-compulsive personality (disorder) (F60.5)
  • obsessive-compulsive symptoms occurring in depression (F32.-, F33.-)
  • obsessive-compulsive symptoms occurring in schizophrenia (F20.-)
