Use additional code
Report an additional code alongside T63.4 to fully describe the condition. T63.4 is sequenced first.
- code, if applicable, for anaphylactic shock (T78.2)
Excludes1 — never code together — inherited from T51-T65
The conditions below can never be reported together with T63.4 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- contact with and (suspected) exposure to toxic substances (Z77.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside T63.4 to fully describe the condition. T63.4 is sequenced first.
