R11: Nausea and vomiting

Non-billable headerICD-10-CM

R11 is a non-billable header ICD-10-CM code for nausea and vomiting. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

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)

Other codes that can never be billed with R11

Their own Excludes1 notes name this code, so the conflict is not listed above.
