Excludes1 — never code together

The conditions below can never be reported together with G25.5 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • chorea NOS with heart involvement (I02.0)
  • Huntington's chorea (G10)
  • rheumatic chorea (I02.-)
  • Sydenham's chorea (I02.-)
