Excludes1 — never code together
The conditions below can never be reported together with T41 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

- toxic reaction to local anesthesia in pregnancy (O29.3-)
Code first — inherited from T36-T50
The underlying condition below must be sequenced before T41. T41 describes a manifestation and cannot be the principal or first-listed diagnosis.
Use additional code — inherited from Chapter 19
Report an additional code alongside T41 to fully describe the condition. T41 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 T41, but a patient may have both at the same time. When documentation supports it, T41 and the excluded code may both be reported.
