Excludes1 — never code together — inherited from T36-T50
The conditions below can never be reported together with T43.2 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 T43.2. T43.2 describes a manifestation and cannot be the principal or first-listed diagnosis.
Use additional code — inherited from Chapter 19
Report an additional code alongside T43.2 to fully describe the condition. T43.2 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 T43.2, but a patient may have both at the same time. When documentation supports it, T43.2 and the excluded code may both be reported.
