T78.0 — Anaphylactic reaction due to food
Not billable
Is T78.0 billable?
No — T78.0 is a non-billable header code. T78.0 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 42 billable codes beneath T78.0.

Use additional code — inherited from Chapter 19
Report an additional code alongside T78.0 to fully describe the condition. T78.0 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of T78.0, but a patient may have both at the same time. When documentation supports it, T78.0 and the excluded code may both be reported.
Excludes2 — not included here — inherited from T78
The conditions below are not part of T78.0, but a patient may have both at the same time. When documentation supports it, T78.0 and the excluded code may both be reported.
- complications of surgical and medical care NEC (T80-T88)
Code also — inherited from T66-T78
Two codes may be needed to describe the condition fully. Whether T78.0 is sequenced first depends on the reason for the encounter.
- , if applicable, place of occurrence, such as:
- highway rest stop (Y92.523)

- service areas as the place of occurrence of the external cause (Y92.52-)
- single-family non-institutional (private) house as the place of occurrence of the external cause (Y92.01-)
- transport vehicle as the place of occurrence of the external cause (Y92.81-)

How long has T78.0 existed?
T78.0 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
