What is the correct way to code a pt diagnosed with allergic reaction to insect bite?
Would you use just use 995.3 and E906.4, or also add the insect superficial injury code? I am asking specifically for insects (mosquitos and ticks), not for bees, wasps, and hornets.

I would also add the bite from insect 919.4 which is an unspecified site. If you know the site you can be more specific. :)
