Excludes1 — never code together — inherited from T36-T50
The conditions below can never be reported together with T38.8 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

Excludes1 — never code together — inherited from T38
The conditions below can never be reported together with T38.8 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Code first — inherited from T36-T50
The underlying condition below must be sequenced before T38.8. T38.8 describes a manifestation and cannot be the principal or first-listed diagnosis.
Use additional code — inherited from Chapter 19
Report an additional code alongside T38.8 to fully describe the condition. T38.8 is sequenced first.

Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of T38.8, but a patient may have both at the same time. When documentation supports it, T38.8 and the excluded code may both be reported.
