A05: Other bacterial foodborne intoxications, not elsewhere classified

Non-billable headerICD-10-CM

A05 is a non-billable header ICD-10-CM code for other bacterial foodborne intoxications, not elsewhere classified. 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.

Clostridium difficile foodborne intoxication and infection (A04.7-)
Escherichia coli infection (A04.0-A04.4)
listeriosis (A32.-)
salmonella foodborne intoxication and infection (A02.-)
toxic effect of noxious foodstuffs (T61-T62)

Other codes that can never be billed with A05

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

G70Myasthenia gravis and other myoneural disorders
A04Other bacterial intestinal infections
A48.5Other specified botulism
T61Toxic effect of noxious substances eaten as seafood
T62Toxic effect of other noxious substances eaten as food
