Not coded here — these two are mutually exclusive.

“halogen derivatives of aliphatic and aromatic hydrocarbons (T53.-)”

An Excludes1 note means the two conditions cannot occur together, so the pair should not be reported for the same encounter. The sole exception is when the conditions are documented as unrelated to each other.
