About A48.5

A48.5 is the ICD-10-CM diagnosis code for other specified botulism. It belongs to category A48 (other bacterial diseases, not elsewhere classified), block A30-A49 (other bacterial diseases) and chapter 1 (certain infectious and parasitic diseases). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within A48, choose A48.5 (Other specified botulism) only when documentation doesn't support a more specific option: gas gangrene (A48.0), Legionnaires' disease (A48.1), Nonpneumonic Legionnaires' disease [Pontiac fever] (A48.2), toxic shock syndrome (A48.3), Brazilian purpuric fever (A48.4) and other specified bacterial diseases (A48.8).

To report this condition, pick the subcode that matches the documentation: A48.51 (botulism) and A48.52 (botulism).

Don't report A48.5 together with the conditions in its Excludes1 note: food poisoning due to toxins of Clostridium botulinum (A05.1).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
