Excludes1 — never code together
The conditions below can never be reported together with T75 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- adverse effects NEC (T78.-)
Excludes2 — not included here
The conditions below are not part of T75, but a patient may have both at the same time. When documentation supports it, T75 and the excluded code may both be reported.
- burns (electric) (T20-T31)
Use additional code — inherited from Chapter 19
Report an additional code alongside T75 to fully describe the condition. T75 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 T75, but a patient may have both at the same time. When documentation supports it, T75 and the excluded code may both be reported.
Code also — inherited from T66-T78
Two codes may be needed to describe the condition fully. Whether T75 is sequenced first depends on the reason for the encounter.
- , if applicable, place of occurrence, such as:
- highway rest stop (Y92.523)
- school (private) (public) (state) as the place of occurrence of the external cause (Y92.21-)
- 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-)
