Excludes1 — never code together

The conditions below can never be reported together with R11 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • cyclical vomiting associated with migraine (G43.A-)
  • excessive vomiting in pregnancy (O21.-)
  • hematemesis (K92.0)
  • neonatal hematemesis (P54.0)
  • newborn vomiting (P92.0-)
  • psychogenic vomiting (F50.89)
  • vomiting associated with bulimia nervosa (F50.2-)
  • vomiting following gastrointestinal surgery (K91.0)

Excludes2 — not included here — inherited from Chapter 18

  • signs and symptoms of breast (N63, N64.5)

Excludes2 — not included here — inherited from R10-R19
