I would think the chemical injected into a wart would be inclusive in the lesion destruction procedure. J9040 is used for chemotherapy treatment.

You need to calculate the total number of units you injected. How many units was in the 0.1CC?
J9040 is for 15 units of belo administered.
Lets say you injected only 3 units, but since the J-code J9040 is for 15 units administered You still round up to to J9040 x 1. You cannot bill for a partial J9040. You always round up to the nearest.
Also, use 11900 series for warts. Bleo is used for wart injections quite frequently in dermatology.
